Product Introduction
RX21 series vitreous‑enamel wirewound resistors are compact‑size power wire‑wound resistors. Alloy resistance wire is tightly wound on high‑temperature ceramic core, then covered with high‑performance vitreous enamel insulating protective layer. With small outline dimension, reliable insulation, low temperature drift and stable resistance value, RX21 is widely adopted for current‑limiting, voltage‑dropping, load and bleeder circuits in various electronic and industrial devices.
Key Features
- Compact body, space‑saving installation
- Vitreous enamel coating: moisture‑proof, anti‑vibration, anti‑corrosion
- Stable resistance value, low temperature coefficient
- Good overload capacity and excellent heat dissipation
- Multiple power grades for selection
- Custom resistance values are supported
Applications
- Switching power supply, UPS power units
- Industrial control cabinet
- Electronic instruments & meters
- Household electrical equipment
- Current‑limiting, bleeder and load circuits
