The SQ1212 redefines space constrained EMI filtering with its vertical design and advanced flat wire windings. Engineered for next-generation power supplies, automotive systems, and IoT devices, flat wire inductor cuts copper losses by 40% versus round wire chokes, radically improving thermal stability and current handling in micro-footprint designs.

Advantages

✅ Flat Wire Technology:

Radial Heat Dissipation: Optimized thermal management enables 25% higher continuous current vs. same-size round-wire chokes.

Low Skin Effect Losses: Maintains high Q-factor at MHz frequencies for efficient filtering in GaN/SiC circuits.

✅ Ultra-Low-Profile Vertical Design (2.5mm max height):

70% PCB area savings vs. horizontal mounting

Airflow-optimized for forced convection cooling

Robust SMT solder joints withstand 5,000+ thermal cycles

✅ Reliability:

Triple-insulated flat wire (2000VAC isolation)

Self-damping windings eliminate acoustic noise

-40°C to +150°C operational range

✅ EMC Compliance Accelerator:

Targets conducted EMI from 150kHz to 300MHz

CISPR 32/EN 55032 Class B compliant (with recommended circuit)

Electrical characteristics: (at 25℃)

PCB board aperture ≥ Ø1.2mm
