Product Overview
This series of surface-mount inductors are designed for high-power applications, offering a compact and ultra-thin profile with high saturation and low resistance. Featuring a magnetic-resin shielded structure, they significantly reduce buzz noise and magnetic leakage, providing strong anti-EMI capabilities. These inductors offer a rated current over 30% higher than traditional inductors of the same size and operate across a wide frequency range, extending beyond 5MHz. They are RoHS and halogen-free compliant, making them an environmentally conscious choice for various electronic systems.

Remarks on Specifications
- 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
