Bourns Magnetics Product Line is pleased to introduce the Model SM91243L Reinforced Gate Driver Transformer.
The DFM (Design for Manufacturing) overmolding process delivers a compact size with reinforced insulation.
This gate driver transformer provides very low interwinding capacitance (Ciw) and leakage inductance (Lk). Additionally, the Model SM91243L is developed for use with the Allegro Micro Model AHV85000 and AHV85040 GaN FET Isolated Gate Driver Chipsets.
The Model SM91243L is manufactured with a fully automated process to ensure high quality and costeffectiveness. This component offers a working voltage of up to 1000 V and a Hi-Pot isolation voltage up to 5000 VAC with an extended operating temperature range of -40 to +125 °C. The device provides a 10 mm minimum clearance and creepage distance with reinforced insulation.
