TDK Power Ferrite: PC95 versus PC50
TDK Corporation has announced the intention to discontinue the PC50 power material. The factory is replacing the PC50 material with PC95 material on all quotations. Therefore it is imperative that we understand the differences between the PC50 and PC95.
PC50 History – The PC50 material was announced in 1988 after years of developing new processes for powder preparation and Sintering. The PC50 material was the first ferrite material design for the operating frequency of 500 KHz – 1MHz. A review of the power material can be found in the paper entitled Ferrite power material for high-frequency applications by Tadashi Mitsui and Gary Van Schaick. This document can be found at:
