Ultrasonic sensor transformer '5RFH/5RFHB/5RGHB'

The inductance value can be adjusted! It is suitable for driving ultrasonic sensors.

The "5RFH/5RFHB/5RGHB" is a transformer for ultrasonic sensors that achieves an inductance tolerance of 3%. By realizing products with narrow tolerance on L values, it prevents malfunction of the module. It extends the overlapping characteristics compared to our conventional products, making it usable even in modules with larger currents. Additionally, to suppress frequency shifts in LC resonance due to temperature, materials with low temperature coefficients have been selected and used. 【Features】 ■ Achieves an inductance tolerance of 3% ■ Adopts a shielded structure with a case that is less susceptible to external noise ■ Suitable for driving ultrasonic sensors ■ Operating temperature range: -40℃ to +125℃ (including self-heating) *For more details, please refer to the PDF document or feel free to contact us.

Vehicle-mounted pulse transformer "VEPS1313A"

Leakage inductance decreased by 10% compared to our company standard.

Vehicle-mounted pulse transformer "VEPS1313A" (W14.3mm×D17.8mm×H12.8mm) This product is an arrangement of our existing product "VEP1313A" with a GAP of "0," resulting in a 10% reduction in leakage inductance compared to the conventional product. As a result, it becomes easier to insulate parts that are susceptible to external noise, contributing to the overall improvement of the circuit's power efficiency.

Ultra High Voltage Resistance On-Board DC/DC Converter Transformer 'VER9060V'

Improving insulation performance in light of the high voltage of EV systems.

We are pleased to announce the development of the automotive DC/DC converter transformer "VER9060V" (W14.9mm × D10.0mm × H6.2mm), with sample availability starting in February 2025. This product enhances insulation performance in our automotive transformer "VER series," taking into account the recent trend towards higher voltages in xEV systems. The "VER9060V" improves voltage resistance by using FIW wire (fully insulated wire) for both the primary and secondary windings. By adopting a material with a CTI LV.1 rating for the base, we have minimized the required creepage distance (in accordance with IEC 60664). The VER series features a product structure that allows the core to be housed in the dead space of the base, achieving a low profile and compact design while maintaining ultra-high voltage resistance. As a result, this product is suitable for inverters for xEVs and flyback transformers for battery junction boxes. We will continue to expand our lineup to meet further market needs and provide a wide range of solutions.

BMS transformer "VHK1550V"

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
