Product Description
Product Overview
This series of surface-mount, miniature, and ultra-thin inductors are engineered for high power applications, offering high saturation current and low resistance. Featuring a magnetic-resin shielded structure and a closed magnetic circuit design, these inductors significantly reduce buzz noise and magnetic leakage, providing strong anti-EMI capabilities. They deliver over 30% higher rated current compared to traditional inductors of the same size and operate across a wide frequency range, extending beyond 5MHz. These products are RoHS and Halogen-free compliant, making them an environmentally responsible choice for various electronic designs.

- Notebooks, desktop computers, servers, graphic cards
General Specifications:
- Operating Temperature: -25 ~ +125
- Inductance Tested at 1MHz, 0.25Vrms (20) for CKCS201610 series.
- Inductance Tested at 100kHz, 1Vrms (20) for other series unless otherwise noted.
- 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.
