Coilcraft releases HTX7045C series transformers that feature a chip-style construction – a significant advancement over traditional core and bobbin designs that not only reduces the size of the component, but also streamlines the manufacturing process, resulting in a more cost-effective solution.
It offers low interwinding capacitance (as low as 0.7 pF), making it particularly well-suited for use in isolated gate driver bias supplies employing the open-loop LLC transformer topology to achieve ultra-low EMI noise and high CMTI (Common Mode Transient Immunity).
These characteristics make it especially beneficial for high-frequency switches including SiC, GaN and IGBT technologies.
The HTX7045C is AEC qualified, making it ideal for automotive traction inverters and motor controls, automotive on-board chargers (OBC), EV charging stations, battery management systems (BMS), automotive DC-DC converters and wide range of other automotive and industrial applications.
Features
- Low interwinding capacitance (as low as 0.7 pF) to minimize EMI and achieve high Common Mode Transient Immunity (CMTI)
- Optimized for isolated bias supplies for SiC and GaN gate drivers, such as the UCC25800-Q1 from Texas Instruments
- Ideal for automotive traction inverters and motor controls, automotive OBCs, EV charging stations, battery management systems, and wide range of other automotive and industrial applications
- Highly automated production process reduces cost and results in exceptional quality and reliability
- 2800 Vrms, 4000 VDC, one minute isolation (hipot) between primary and secondary windings in a package measuring just 4.85 x 7.20 x 5.30 mm
- AEC-Q200 (–40°C to +125°C)
