Compact SMD Flat High-Performance Ultra-Low DCR Common Mode Choke for Power Supply Noise Filter

Key Features
Engineered for modern power electronics, the SQS1010A Series represents a line of high-quality SMD inductors specifically designed as common mode chokes for superior electromagnetic interference suppression. Utilizing a square core structure and high-permeability material, these low DCR common mode chokes achieve high impedance at low frequencies with minimal leakage and exceptionally low power loss. Their compact SMD flat design offers significant space savings on PCBs, making them an ideal, cost-effective solution for high-density power circuits requiring reliable noise attenuation and high insulation resistance. Fully compliant with RoHS and REACH standards, they are produced with high consistency through automated manufacturing.

Features:

• Compact SMD flat package for space-constrained PCB designs.

• Square core construction for low leakage and reduced DC resistance (DCR).

• High-permeability material ensures high impedance at low frequencies.

• Excellent noise attenuation due to low stray capacitance.

• High insulation resistance and UL94V-0 flammability rating.

• RoHS and REACH compliant, suitable for global markets.
