Product Description
Product Overview
This series of inductors are designed for surface mounting, offering a compact and ultra-thin profile with high power handling capabilities, high saturation, and low resistance. They feature a magnetic-resin shielded structure that significantly reduces buzz noise and a closed magnetic circuit design to minimize magnetic leakage flux and enhance anti-EMI performance. These inductors provide a rated current over 30% higher than traditional inductors of the same size and operate across a wide frequency range, up to 5MHz and above. They are RoHS and Halogen-free compliant, making them environmentally friendly solutions for various electronic applications.

Specification Remarks
- Inductance Tested at 1MHz, 0.25Vrms (20) for some series, and 100kHz, 1Vrms (20) for others.
- Isat: DC current at which the inductance drops approximately 30% from its value without current.
- Irms: DC current that causes the temperature rise (T = 40C) from 25C ambient.
- Operating Temperature: -25 ~ +125
