Product Description
Product Overview
This series of inductors features a metallization on the ferrite core for excellent shock resistance and damage-free durability. The closed magnetic circuit design minimizes leakage flux and Electro Magnetic Interference (EMI), while the Fe base metal material core ensures a large saturation current. Automatic production guarantees high quality and consistency, making these inductors suitable for a wide range of electronic applications including notebooks, desktop computers, servers, graphic cards, set-top boxes, automotive systems, and portable multimedia devices.
Product Attributes
- Core Material: Fe base metal
- Construction: Ferrite core with metallization
- Production: Automatic

Remarks:
- Inductance Tested at 1MHz, 0.25Vrms (20)
- Isat: DC current at which the inductance drops approximate 30% from its value without current.
- Irms: DC current that causes the temperature rise (T =40C) from 25C ambient.
- Operating Temperature: -40 ~ +125
- Absolute maximum voltage: DC 25V.
