SMD Power Inductor - CKCS Series
Product Overview
The CKCS Series SMD Power Inductors are compact, ultra-thin surface-mount components designed for high-power applications. They feature high saturation, low resistance, and a magnetic-resin shielded structure that significantly reduces buzz noise and enhances anti-EMI capabilities due to a closed magnetic circuit design with minimal leakage flux. These inductors offer over 30% higher rated current compared to traditional inductors of the same size, making them ideal for demanding applications in PADs, notebooks, servers, audio systems, networking equipment, security devices, mobile phones, smart home devices, and energy storage systems.

Technical Specifications
General Notes:
1. All test data is referenced to 25 ambient.
2. Inductance Tested at 1MHz, 0.2Vrms or 100kHz, 1Vrms (depending on specific series/part number).
3. Isat: DC current at which the inductance drops approximately 30% from its value without current.
4. Irms: DC current that causes the temperature rise (T 40) from 25 ambient.
5. Absolute maximum voltage: DC 50V (or DC 100V for certain high-voltage parts).
