ST710PGP Series
Power Inductors for Critical Applications
ST710PGP Series is designed for high-efficiency power supplies requiring high current and high inductance.
- Designed for high temperature environments – up to 140°C ambient
- Developed for high current power supply applications with high saturation current requirements
- Four additional mounting pins provides stability and excellent board adhesion in high-vibration environments
- Flat wire windings for extremely low DC and AC resistance

Notes
- When ordering, please specify screening code: e.g. ST710PGP333KLZ.
- Inductance tested at 300 kHz, 0.1 Vrms on Agilent/HP 4192A.
- DCR measured on a Keithley 580 micro-ohmmeter or equivalent.
- SRF measured on an Agilent/HP 4395A network analyzer and an Agilent/HP 16093B test fixture.
- 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.
