Date: August 1, 2016 – Toroidal Core Process Change

TDK Corp has officially announced a process change in the epoxy coating of the ferrite toroid cores. The location of the epoxy coating of the toroidal ferrite cores is changing as of August 1, 2016. Before this date, the epoxy coating of the toroidal ferrite cores was done in Japan. After August 1, 2016, the epoxy coating of the toroidal ferrite cores will be in China. The technical specifications of the epoxy coating have not changed.

The manufacture of the toroid ferrite cores as to the electrical and mechanical specifications before coating has not changed. Samples of the process as it pertains to the epoxy coating in the China locations will be available as required.

Date: September 1, 2012 – Process Change Update

In March/April TDK announced they would be moving the Powder process facility from Japan to Xiamen. At the time the estimated timeframe was sometime the end of Summer to Autumn. TDK has updated the dates for this move.

The powder process facility will stop processing powder towards the end of September once it has made all the powder needed to fulfill current orders through December. The movement of the facility is estimated to take two months ( October – November). The estimated time for Powder production to start up in Xiamen, China is sometime in December with resulting new core orders using the new facility to be January (x-factory).

TDK has a supply of raw material in all of the material grades, however the availability of the powder will depend on new order entry from across the world. The worst case scenario for new Core orders requiring a plant order will be a ship date to our customer of mid-February. The material most affected is:

H5A
H5B2
H5C2
HS52
PC50
DN70
Others

Secondly, PC90 and PC95 will be affected however the factory has quite a large inventory of this material. So far we continue to receive Nov – Dec deliveries for PC95 & PC90 ( about 14 week lead time)

Third: The manufacture of the large cores will be moving to China in the same time frame. This includes the large toroids (above 18mm) and large cut cores as the EC70 and EC90. The tools and presses will be dismantled, packed and shipped to China with an estimated install date of early December with production estimated to be early January.

Fourth: It has been announced that while the manufacture of toroids requiring Epoxy coating is being moved to China, the Epoxy coating process is not being moved. Toroids requiring Epoxy coating will be manufactured in China and shipped to japan for final process of Epoxy coating. This effectively adds abour four weeks to the lead time for manufacture.

PC40/PC44/PC47 is already produced in Xiamen. Lead time on this material is only affected by the rate of incoming orders on the factory and resulting factory scheduling and remains about 13 weeks.

Date: March 1, 2012 – Notification of large Size Ferrite Cores to be Discontinued

TDK has made the announcement that the large sized ferrite cores are to be discontinued. Please see the attached list:

Large Size Ferrite Cores for High Power_Discontinue List 030112

The cores on the list designated as “Discontinue” will be discontinued with a last time buy of June 30,2012. The cores on the list designated as “No New Design” are scheduled to be discontinued at some time in the future, no yet determined.

In addition to the indicated cores being discontinued, the manufacturing of the following cores are being moved from Japan to China:

All Toroids in the sizes of 18mm and above
EC70 cores
EC90 cores

Date: March 1, 2012 – Notification of Ferrite Core Shape EE5 to be Discontinued

TDK has made the announcement that the EE5 core shape will be Discontinued. The last date for the acceptance of orders for the EE5 will be June 1, 2012. This affects the MH&W International custom core PC44 EE05-Z A220 min.

MH&W International, in cooperation with China Manufacturing Technology (CMT), has released a suitable replacement for the EE5 core such that our customers can continue to design in and purchase the EE5 core. The power material that we are purchasing will be the FP3H material. The material specifications are here: Power Ferrite FP3H The FP3H material is equivalent to the TDK PC95 material. The EE5 core specification has a minimum Al value of 270. The replacement core that MH&W is offering is a better core in terms of core loss and inductance. The core spec is here: CMT FP3H EE5 A270M

Update: February 1, 2012 – Movement of Ferrite Manufacturing to Xiamen, China:

2007 – TDK made the announcement of a process change whereas the manufacturing of ferrite would move from Japan to China. This movement would be accomplished in three (3) phases.

Phase one -2008: The Grinding and Gapping subprocess in Narita, Japan would be moved to Xiamen, China.

Phase two – 2009 – 2010: The Pressing and Sintering subprocess at Narita, Japan would be moved to Xiamen, China.

Phase three : The Powder Preparation subprocess would be moved to China. TDK has now announced the timeframe for the completion of this process which includes moving the powder preparation subprocess of certain materials from the Anakura Plant in Japan to the Xiamen Plant in China. The powder preparation subprocess of the ferrite materials that are moving are: DN50, DN70, H5A, H5B2, H5C2, H5C3, H5C4, PC33, PC50, PC90 & PC95. There is no change or alteration of the process nor the specification of the materials or cores.

Effective timeframe for the movement of the powder preparation process: July 1 – September 30, 2012

Date: June 1, 2011 – Notification Of Reduced Material Availability

TDK corporation has introduced the PC47 Power Material as the next generation power material to replace both PC40 and PC44 power materials. The greatest advantage of PC47 is the lowest possible core losses (250 KW/M3) at 100°C, 100KHz and 200mT. The saturation is also improved to be greater than 420mT at 100°C. This is the material for new designs and to replace PC40/PC44 for greater efficiency.

TDK now offers a three-pack of power for new power magnetics design, PC47 for the lowest core losses at 100°C, PC90 for the highest possible saturation and PC95 for the lowest core losses from -40°C – 120°C. TDK will continue to support older designs in PC40 and PC44 for an undetermined period of time.

Date: April 1, 2011 – Update – TDK Ceases Supplying Bobbins/Accessories

April 1, 2010, TDK announced their intension to cease supplying the bobbin and accessories that go with their ferrite cores. At that time, TDK accepted last time orders. MH&W notified all our customers of the last time buy and that MH&W would accept delivery requirements until March, 2011. As of today, TDK has ceased supplying bobbin and accessories and MH&W can only accept purchase orders for that product that is in our inventory.

MH&W International has purchased inventory on the active parts to continue supplying these active parts for a period of approximately three (3) years. during that time we will be attempting to find alternate sources of supply for close equivalents of the bobbins and accessories that TDK no longer supplies.

Date: April 1, 2010 – Notification Of Process Change

TDK-EPC (magnetic group of TDK Corporation) has announced the intention to discontinue the manufacture of all TDK Proprietary bobbins and mounting hardware currently being supplied by MH&W International Corp. The bobbins and mounting hardware produced by Epcos Corp are not affected and in many cases MH&W will offer Epcos bobbins and mounting hardware as the alternative product.

MH&W International will continue to support the product for a period of 12 months from the announcement date above by giving our customers a last time buy and allowing the delivery of the product to be scheduled. TDK Corp has agreed to allow MH&W International a last time buy on all active products. In order to consolidate orders and transmit purchase orders to the factory, MH&W Int’l needs from our customers their last time buy by June 10, 2010. MH&W Int’l will then allow delivery of that product over the time frame to complete the purchase orders by March 31, 2011.
