MS412PJB Series
High-Reliability Power Inductors
MS412PJB Series offers high temperature materials allowing operation in ambient temperatures up to 155°C.
- Special construction allows it to pass vibration testing to 80 G and shock testing to 1000 G.
- Tin-lead (Sn-Pb) termination for the best possible board adhesion.
- Tin-lead (63/37) over tin over nickel terminations.

Notes
- When ordering, please specify screening code: e.g. MS412PJB333MSZ.
- Inductance tested at 100 kHz, 0.1 Vrms using an Agilent/HP 4192A. Inductance at 1 MHz is the same for parts with SRF ≥10 MHz.
- DCR measured on a micro-ohmmeter.
- SRF measured using an Agilent/HP 8753ES or equivalent.
- DC current at 25°C that causes the specified inductance drop from its value without current.
- Current that causes the specified temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings.
Screening:
- Z = Unscreened
