Document MS198-1 Revised 07/13/12

This 0402 size chip inductor series shares all of the

characteristics of Coilcraft’s other ceramic inductors: ex-

ceptionally high Q factors, especially at use frequencies;

outstanding self-resonant frequency; tight inductance

tolerance; and excellent batch-to-batch consistency.

This robust version of Coilcraft’s standard 0402CS series

features high temperature materials that allow operation

in ambient temperatures up to 155°C and a leach-resis-

tant base metalization with tin-lead (Sn-Pb) terminations

that ensures the best possible board adhesion.
