## Description

The Wurth Elektronik 750311681 is a high-reliability pulse transformer belonging to the WE-FB Series, engineered for precise signal transmission, isolation, and gate drive applications in power conversion topologies. Operating across a temperature range of -40°C to +125°C (including self-heating), this component provides a 10:1 turns ratio with a nominal primary inductance of 100 µH (measured at 50 kHz, 100 mVAC, 20°C with a ±10% tolerance). The primary winding features a low DC resistance (DCR) of 0.22 ohms (±10% at 20°C), minimizing copper losses and optimizing overall circuit efficiency during high-frequency operation.

Designed for robust electrical isolation, the WE-FB series transformer is rated for 1.5 kVAC dielectric withstand voltage applied between windings for 1 second (Terminals 3-10, with 8+9 tied). It exhibits a tightly controlled interwinding capacitance of 30 pF maximum at 100 kHz, 100 mVAC, reducing common-mode noise coupling and high-frequency transient feedback. The saturation current specification supports a 20% inductance rolloff at a 2ADC primary bias, making this pulse transformer suitable for high-frequency switch-mode power supplies, DC-DC converters, and isolated interface circuitry requiring stable transformation ratios and strict galvanic isolation.
