SMD Power Inductor - CKCS Series
Product Overview
The CKCS Series SMD Power Inductors are designed for high-performance applications, featuring a surface-mount, compact, and ultra-thin form factor. These inductors offer high power handling, high saturation, and low resistance. The magnetic-resin shielded structure significantly reduces buzz noise to ultra-low levels, while the closed magnetic circuit design minimizes magnetic leakage flux and enhances anti-EMI capabilities. Compared to traditional inductors of the same size, the CKCS Series provides over 30% higher rated current. They are ideal for use in PADs, Notebooks, Servers, audio equipment, networking devices, security systems, mobile phones, smart home devices, and energy storage equipment.

General Specifications
- Operating Temperature: -40 to +125 (Including self-temperature rise)
- Absolute Maximum Voltage: DC 50V (for most series), DC 100V (for specific higher inductance ranges in CKCS4030, CKCS5040, CKCS6045, CKCS8040, CKCS8060 series)
- Testing Conditions: All test data is referenced to 25 ambient. Inductance tested at 1MHz, 0.2Vrms (CKCS201610) or 100kHz, 1Vrms (other series).
