This New Product Brief (NPB) is part of a video series highlighting the features, applications, and technical specs of newly-released products.

Bel Group Signal Transformer / Bel SPDL Ultra-Compact SMD Common Mode Chokes

Signal Transformer, a Bel company, is now offering the SPDL ultra-compact common mode chokes 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 common mode chokes come in a number of size codes and have two lines, an impedance range from 90 to 2200 ohms, a current capacity from 150 to 400 milliamps, and an operating temperature range from -40 °C to +125 °C.

These ultra-thin common mode chokes come in compact surface mount packages with excellent thermal characteristics and AECQ-200 compliance.

The SPDL chokes are applicable in the consumer, industrial and automotive interface market.
