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. 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 performance. Compared to traditional inductors of the same size, the CKCS series provides over 30% higher rated current. 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.

Note: Test data is referenced to 25 ambient. Inductance is tested at 1MHz, 0.2Vrms or 100kHz, 1Vrms depending on the series. Isat is the DC current at which inductance drops approximately 30% from its value without current. Irms is the DC current that causes a temperature rise (T 40) from 25 ambient. Absolute maximum voltage is DC 50V for most series, with exceptions noted.
