Cores for High-frequency Tube Welding – ZR-configured Impeder Cores

Cores for high-frequency tube welding – ZR-configured Impeder cores made by TDK.

Impeder cores of ZR type have a truncated round cross section and are usually used for making large-size impeders when it is necessary to use a large number of ferrite cores simultaneously. It permits to reduce a cost of finished impeders but a cooling level is in this case significantly less effective than in impeders that are made on basis of ZRS- and ZRSH-configured cores.

On producing impeders, a correct choice of inner diameter of protective casing for ZR-configured Impeder cores should be carefully traced. Decrease of casing’s inner diameter down to a value that is lesser than a recommended value may hinder a correct insertion of ZR cores.
