Key Features
Engineered for robust power management solutions, the SQS1515A Series comprises high-efficiency SMD inductors designed as premier power supply filters. These low DCR common mode chokes leverage a square core and advanced high-permeability material to deliver superior common-mode noise suppression, characterized by high impedance at low frequencies and minimal core leakage. With an extended power rating up to 200W and an exceptionally high withstanding voltage between windings, this series ensures reliable performance in demanding environments. Its compact, flat SMD package saves valuable PCB space while providing high insulation resistance and compliance with RoHS, REACH, and UL94V-0 standards.

Features:

• Compact SMD flat package for high-density PCB designs.

• Square core structure for low leakage and ultra-low DC resistance (DCR).

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

• Excellent noise attenuation due to low stray capacitance.

• High withstanding voltage and high insulation resistance.

• UL94V-0 flammability rating.

• RoHS and REACH compliant.
