FP412D250中文资料西门子数据手册PDF规格书

The differential magneto resistor FP 412 D 250 is a magnetically variable resistor in D-type InSb/NiSb semiconductor material. The MR is glued onto a ferrite substrate and is supplied in a MICROPACK copper/polyimide film package. The basic resistance of each of the magneto resistors is 250 Ω. The series coupled MRs are actuated by an external magnetic field or can be biased by a permanent magnet and actuated by a soft iron target.
