Industry-leading low leakage, high voltage resistance, thickness of 5.0mm.
Vehicle-mounted pulse transformer "VHK1550V" (W24.0mm × D15.0mm × H5.0mm) Achieves a low-profile design with a maximum height of 5mm, making it ideal for implementation in space-constrained devices. Furthermore, by aligning the terminal direction parallel to the winding, the wire extraction distance is optimized, successfully minimizing leakage inductance. This supports high-efficiency and stable power conversion. It also boasts excellent insulation performance, with a high voltage specification of AC 3500Vrms, meeting stringent safety standards and noise resistance requirements. It is an optimal product as a pulse transformer for BMS (Battery Management System) for xEVs. Signal transmission transformer High voltage resistance up to AC 3500Vrms Ensures creepage and clearance distances (primary side - secondary side) of 13mm Min. Low profile (5mm MAX.) Low leakage Operating temperature range: -40℃ to +150℃ (including self-heating) AEC-Q200 compliant
