Engineered for demanding power applications, the SQS1918A Series is a comprehensive lineup of high-performance Common Mode Chokes that deliver superior common-mode noise suppression. These robust Power Inductors are designed to handle high currents up to 10A while maintaining exceptionally Low DCR SMD Choke characteristics, ensuring minimal power loss and maximum efficiency in compact designs. Ideal for high-density power supplies, they offer a wide selection of inductance values to meet precise filtering requirements across a broad power spectrum.

Key Features

• High-Current Performance: Uniquely designed to support very high rated currents, from standard 1.0A up to 10.0A, catering to robust power applications.

• Optimized for Efficiency: The Low DCR SMD Choke design, with resistance as low as 20mΩ, significantly reduces copper losses and improves overall system efficiency.

• Superior Noise Suppression: High-permeability material and low stray capacitance provide high impedance and excellent attenuation of electromagnetic interference (EMI).

• Wide Inductance Range: A broad selection of 17 models with nominal inductance from 0.5mH to 30mH allows for precise circuit tuning.

• Robust & Reliable: Constructed with UL94V-0 compliant materials and offering high insulation resistance, ensuring safety and durability in various environments. RoHS and REACH compliant.
