AE338PWA Series
Outgassing Compliant Power Inductors
The AE338PWA Series is not recommended for new designs, but existing customers will continue to be supported. As an alternative, we recommend the AE338PZA Series which is a drop-in replacement.
AE338PWA Series features very low DCR and excellent current handling.
- High temperature materials allow operation in ambient temperatures up to 155°C.
- Passes NASA low outgassing specifications.
- Soft saturation makes them ideal for VRM/VRD applications.
- Tin-lead (Sn-Pb) termination for the best possible board adhesion.
- Special construction allows it to pass vibration testing to 30 G and shock testing to 500 G.
- Tin-lead (63/37) over tin over nickel over silver terminations.
