Product Description
Product Overview
This series of surface-mount inductors are designed for high power applications, offering compact and thin profiles with high saturation and low resistance. Featuring a magnetic-resin shielded structure to minimize noise and a closed magnetic circuit design for reduced leakage flux and strong anti-EMI capabilities, these inductors provide up to 30% higher rated current compared to traditional inductors of the same size. They operate across a wide frequency range, extending beyond 5MHz, and are RoHS and Halogen-free compliant.
Product Attributes
- Certifications: RoHS, Halogen-free
Technical Specifications
Structural Drawing Components
- Freeite core: Ni-Zn Ferrite
- Winding wire: Polyurethane-copper wire
- Electrode: External electrode
- Epoxy resin containing ferrite powder

Notes 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
