Product Overview
The CKCS Series SMD Power Inductors are designed for surface mounting applications, offering a compact and ultra-thin profile 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 a rated current over 30% higher than traditional inductors of the same size. Ideal for a wide range of electronic devices including PADs, notebooks, servers, audio equipment, networking devices, security systems, mobile phones, smart home devices, and energy storage equipment.

General Notes:
- All test data is referenced to 25 ambient.
- Inductance Tested at 1MHz, 0.2Vrms (for CKCS201610) or 100kHz, 1Vrms (for other series).
- 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.
- Operating Temperature: -40 ~ +125 (Including self-temperature rise).
- Absolute maximum voltage: DC 50V (except for CKCS4030-150uH~330uH, CKCS5040-330uH~470uH, CKCS6045-470uH~680uH, CKCS8040-470uH~680uH, CKCS8060-470uH~680uH which are DC 100V).
