Power Resistor 7W 82Ω
The 7W 82ΩJ power resistor is a cement-coated wirewound resistor designed to safely dissipate high power while maintaining stable resistance. The resistance value of 82 ohms with J tolerance (±5%) makes it ideal for applications requiring accurate current control and heat resistance.
Its ceramic cement body provides excellent insulation and flame resistance, allowing it to operate reliably in high-temperature environments. This resistor is widely used in power supplies, inverters, chargers, motor drivers, LED drivers, and audio amplifiers where heat dissipation and long-term stability are critical.
Features:
- Cement-coated flame-retardant body.
- Wirewound internal construction.
- High thermal stability.
- Strong overload capability.
- Excellent heat dissipation.
- Long service life.
- Moisture-resistant coating.
