Product Overview
The CKCS Series SMD Power Inductors are designed for surface mounting, offering a compact and ultra-thin profile with high power handling capabilities. These inductors feature high saturation and low resistance, making them ideal for demanding applications. Their 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 performance. Compared to traditional inductors of the same size, the CKCS Series offers a rated current that is over 30% higher. They are suitable for a wide range of applications including PADs, notebooks, servers, audio equipment, networking devices, security systems, mobile phones, smart home devices, and energy storage equipment.

Notes:
1. All test data is reference to 25 ambient.
2. Inductance Tested at 1MHz, 0.2Vrms (for CKCS201610) or 100kHz, 1Vrms (for other series).
3. Isat: DC current at which the inductance drops approximate 30% from its value without current.
4. Irms: DC current that causes the temperature rise (T 40 ) from 25 ambient.
5. Operating Temperature: -40 ~ +125 (Including self-temperature rise).
6. Absolute maximum voltage: DC 50V (except where noted).
