The SQ1212 Horizontal Power Common Mode Choke is engineered to effectively suppress electromagnetic interference (EMI) in power supply lines. Featuring a compact, space-saving horizontal design, this component delivers high-performance noise filtering critical for stable power delivery and EMC compliance in demanding applications.

Key Features:

Robust Noise Filtering:

Offers high common-mode impedance to attenuate unwanted high-frequency noise on power lines (input/output), ensuring cleaner DC voltage and preventing interference with sensitive circuitry.

High Current Capacity:

Supports continuous current ratings up to 1A, power common mode chokes are designed for efficient power transfer with minimal voltage drop and core saturation, ideal for switching power supplies, adapters, and industrial power systems.

Wide Temperature Range:

Operational temperature range from -55°C to +125°C, ensuring reliability in harsh environments including automotive, industrial automation, and outdoor equipment.

Low DC Resistance (DCR):

Power common mode choke optimized winding design minimizes DCR to reduce power loss and heat generation, enhancing overall energy efficiency.

Horizontal Design for Space Efficiency:

Low-profile horizontal mounting saves PCB real estate and simplifies layout in densely packed designs.

Electrical characteristics: (at 25℃)

PCB board aperture ≥ Ø1.2mm
