Power Inductors

Coilcraft CPS High-Reliability Power Inductors span a very wide range of low-power applications. Each is designed to perform under harsh conditions for critical product applications. Select a data sheet below or search for a device that meets your design requirements with our inductor finder.

All power inductors are constructed with high temperature material that allows operation in extended ambient temperatures.
MS class power inductors feature tin-lead (Sn-Pb) terminations that ensure the best possible board adhesion.
PJB family passes typical vibration testing to 80 G and shock testing to 1000 G.
