SMD Common Mode Chokes SQS

SQS Family

SMD High Current Flat Wire Common Mode Choke 

The SQS series of SMD Common Mode Chokes represents a breakthrough in electromagnetic interference (EMI) suppression for modern high-density power electronics. Engineered with square-core technology and flat wire winding techniques, these components deliver exceptional noise filtering performance while maintaining an ultra-compact footprint—ideal for space-constrained applications such as consumer devices, industrial power supplies, and automotive systems.

‌KEY FEATURES:‌

•  Compact size without compromising EMI filtering performance
• Low DC resistance (DCR)
• Low-frequency impedance
• Ultra-low stray capacitance delivers exceptional high-frequency noise attenuation—ideal for EMI-sensitive environments such as medical equipment and communication modules.
• Compliant with UL and RoHS
• Insulation resistance ≥100MΩ at 500V DC
• Wide operating temperature range: -40°C to +125°C

‌APPLICATIONS:‌

Our high-performance common-mode chokes are widely used in applications requiring stringent electromagnetic compatibility (EMC).

• They are employed in laptops, smartphones, and smart home devices.
• AC/DC converters for industrial automation equipment.
• Electromagnetic interference (EMI) filtering solutions for DC/DC regulators and power adapters.
• They are also found in consumer electronics such as LCD televisions, gaming consoles, and audio systems.
