    Product Description

    SQS Family

    SMD High Current Flat Wire Common Mode Choke 

    The ‌SMD Common Mode Chokes SQS‌ series delivers advanced ‌EMI Filter‌ performance through optimized square-core design. These ‌High Frequency Common Mode Chokes‌ combine compact size with superior noise suppression, making them ideal for modern power electronics demanding space efficiency and reliability.

    common-mode choke

    FEATURES:
    ・‌SMD Common Mode Chokes SQS‌ utilize square cores for compact size, low DCR, and minimized leakage.
    ・High permeability material enables high low-frequency impedance – critical for ‌Emi Filter‌ stability.
    ・Low stray capacitance ensures high noise attenuation in ‌High Frequency Common Mode Chokes‌.
    ・UL 94 V-0 flammability compliance | RoHS/REACH/Halogen-Free options.
    ・Automated production guarantees low cost and high consistency.
    ・Robust insulation: 2400VAC/60s withstand voltage | 100MΩ Min@500VDC between windings.
    ・Operating/Storage Temp: -40℃~+125℃ / -40℃~+85℃.

    APPLICATIONS:
    ・‌Emi Filter‌ solutions for power supply circuits and high-density switching-mode devices.
    ・Consumer/Industrial electronics: LCD TVs, battery chargers, power adapters, home appliances.
    ・Upgrade path for legacy ‌High Frequency Common Mode Chokes‌ with space-saving advantages.
    ・Drop-in replacement for existing ‌SMD Common Mode Chokes‌ in EMI-sensitive systems.
