Chip Inductors – M1206CS Series (3216)
The M1206CS inductors feature high SRF and excel-
lent Q values. Their ceramic cores make 1% tolerances
practical and economical and ensure the utmost in
thermal stability, predictability and consistency.
This robust version of Coilcraft’s standard 1206CS series
features a high temperature encapsulant that allows op-
eration in ambient temperatures up to 155°C and a leach-
resistant base metalization with 63/37 tin-lead terminations
that ensures the best possible board adhesion.
