SPDL Ultra-Compact SMD Common Mode Chokes

Signal Transformer / Bel SPDL Ultra-Compact SMD Common Mode Chokes are designed for EMI suppression of differential mode noise. They feature high common-mode impedance in the noise band and low differential mode impedance in the signal band. A low differential mode impedance with a high coupling coefficient ensures virtually no distortion of high-speed signals. The SPDL series offers ultra-thin, compact SMD packages with excellent thermal characteristics and AECQ-200 compliance. Other features include 90Ω to 2200Ω impedance range at 100MHz, 150mA to 400mA current capacity, and -40°C to +125°C operating temperature range.
