The SQ1010 horizontal flat wire common mode choke leverages precision flat wire winding technology to deliver exceptional current handling and EMI suppression in an ultra-slim profile. Designed for modern high-density electronics, it optimizes PCB space while minimizing power losses.
Flat Wire Common Mode Choke Advantages
✅ Advanced Flat Wire Construction:
Lower DC resistance (DCR) vs. round wire
Reduced AC losses at high frequencies
Improved thermal dissipation
Higher saturation current ratings
✅ Space-Optimized Horizontal Mounting:
Ultra-low height profile (typically ≤5mm)
10×10mm compact SMD footprint
Common mode choke ideal for height-restricted enclosures
✅ Performance-Driven Design:
Optimized for high-current power lines (5A–15A+)
Superior common-mode noise attenuation (50MHz–1GHz+)
Stable inductance under heavy loads
-40°C to +125°C operating range
