Coilcraft MS338PWA501MSZ High reliability power inductor Datasheet

2010 POWER INDUCTORS
High Reliability Power Inductors MS338PWA
■ High temperature materials allow operation in ambient
temperatures up to 155°C
■ Very low DCR and excellent current handling.
■ 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.
Weight 20 mg
Terminations Tin-lead (63/37) over tin over nickel over silver.
Ambient temperature –55°C to +105°C with Irms current, +105°C
to +155°C with derated current
Storage temperature Component: –55°C to +155°C.
Packaging: –55°C to +80°C
Resistance to soldering heat Max three 40 second reflows at
+260°C, parts cooled to room temperature between cycles
