Air Core Inductors (Springs)

Coilcraft CPS Air Core Inductors are designed for VHF-UHF RF applications requiring aerospace / military-level performance. Inductance linearity of the coil is not affected by changes in current, so that performance is maintained and unwanted harmonics are minimized. Eight series are available to ensure a match for your application.

AE Outgassing Compliant parts pass NASA low outgassing specifications, have high temperature construction (up to 155°C ambient) and feature tin-lead terminations.
AT Ultra High Temperature parts feature an extended temperature range (–60°C to +200°C or +240°C), pass NASA low outgassing specifications, and have tin-lead terminations.
MS High-Reliability parts feature high temperature construction (up to 155°C ambient) and tin-lead terminations.
ML High-Reliability parts feature high temperature construction (up to 155°C ambient) and are RoHS compliant.
ST Class parts offer extended qualification and are available with tin-lead or tin-silver-copper terminations.
