0402 CHIP INDUCTORS
Aerospace Grade Chip Inductors
AE235RAM
■
Higher inductance values than other 0402 inductors
■
Ferrite construction for high current handling
■
23 inductance values from 20 nH to 560 nH
This robust version of Coilcraft’s standard 0402AF series
features high temperature materials that pass NASA low
outgassing specifications and allow operation in ambient
temperatures up to 155°C. The leach-resistant base
metalization with tin-lead (Sn-Pb) terminations ensures the
best possible board adhesion.
