•

Temperature rise current and saturation current is less

influenced by environment

•

Shield has solderable tabs for additional mounting stability

Applications: Designed for high current power supply

applications

Operating Temperature: -40°C to 125°C (including temperature

rise)

Inductance Tolerance: ±20%

Packaging: Tray packaging

Samples available. See website for ordering information.
