1W Flameproof Cylindrical Cement Wire Wound Resistor for Industrial Power Supplies
- Standard taping package allows for automatic insertion and forming.
- A fully automated process and strict quality control system result in uniform quality and consistent performance in reliability.
- The small and lightweight body style saves considerable PWB space.
- High Dielectric Withstanding Voltage up to 1KV. Flameproof construction in a ceramic tube, resistant to humidity and insulation.
The ROP series cylindrical cement wire-wound resistors are high-reliability power resistors designed specifically for industrial electronic equipment, power systems, automated control equipment, and electronic control boards. The products utilize a flame-retardant ceramic tube structure and wire-wound resistor technology, ensuring stable electrical performance while possessing excellent insulation and moisture resistance.
As a professional wire wound resistor manufacturer providing industrial-grade solutions, this series of products is manufactured through a fully automated production process and a strict quality control system, meeting the stability, consistency, and safety requirements of equipment operating continuously for extended periods.
Its maximum withstand voltage of AC1000V makes it suitable for applications such as power protection, voltage division, current limiting, and industrial control circuits.
