  • Complies with AEC-Q200
  • Unique metal composite core material leads to special benefits (e.g. low saturation, low loss at high frequency, stable over temperature)
  • Designed for harsh environments up to 180°C and 50G vibration
  • Line-up ranges from 0.33μH to 100μH in case sizes from 5x5mm to 12x12mm
  • Recommended for filter and DC/DC applications

Line-up of automotive power inductors

Panasonic metal composite SMD power choke coils (PCC) are specially designed for automotive use and feature superior robustness and high reliability. Performance attributes include non-saturation behavior, low losses and stability over a wide temperature range. This results in downsized components.
