MS319PZA Series
High-Reliability Power Inductors
MS319PZA Series features soft saturation making them ideal for VRM/VRD applications.
- High temperature material allows operation in ambient temperatures up to 155°C.
- Tin-lead (Sn-Pb) termination for the best possible board adhesion.
- Lowest profile, ultra-miniature, magnetically shielded power inductor; only 0.5 mm high, 2 mm × 2 mm footprint.
- Special construction allows it to pass vibration testing to 80 G and shock testing to 1000 G.
- Tin-lead (63/37) over tin over nickel over silver-platinum terminations.

Notes
- When ordering, please specify screening code: e.g. MS319PZA681MSZ.
- Inductance tested at 100 kHz, 0.1 Vrms, 0 Adc.
- DCR measured on a micro-ohmmeter.
- SRF measured using Agilent/HP 4395A or equivalent.
- DC current at 25°C that causes the specified inductance drop from its value without current.
- Current that causes the specified temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings.
