Product Overview
The CKCS Series SMD Power Inductors are designed for surface mounting, offering a compact and ultra-thin form factor with high power handling, high saturation, and low resistance. Featuring a magnetic-resin shielded structure and a closed magnetic circuit, 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. Ideal for applications including PADs, notebooks, servers, audio equipment, networking devices, security systems, mobile phones, smart home devices, and energy storage equipment.

Technical Specifications
General Specifications:
- Operating Temperature: -40 ~ +125 (Including self-temperature rise)
- Absolute Maximum Voltage: DC 50V (for most models, DC 100V for select higher inductance values in CKCS4030, CKCS5040, CKCS6045, CKCS8040, CKCS8060 series)
- All test data is referenced to 25 ambient.
- Isat: DC current at which the inductance drops approximately 30% from its value without current.
- Irms: DC current that causes the temperature rise (T 40) from 25 ambient.
