3.9K Ohm 5 Watt Wirewound Cement Resistor

This 3.9K ohm 5 watt wirewound cement resistor is engineered for high-power applications that demand exceptional heat dissipation, durability, and safety. Ideal for power supplies, motor control, industrial automation, audio amplifiers, and load testing equipment.

High Power Handling with Flame Proof Safety

With a 5 watt power rating and robust cement housing, this wirewound resistor delivers excellent pulse-withstanding capability and flame proof construction. Its designed for safe, reliable operation in high-current, surge-prone, and safety-critical circuits. Physical size: 0.88″L x 0.38″W x 0.38″H (Approximate).

Wirewound Construction for Maximum Performance

The precision wirewound element ensures consistent resistance values, low noise, and excellent thermal stability. This makes it suitable for AC and DC circuits, surge protection, bleeder circuits, and inrush current limiting applications.

Durable Cement Body for Heat Dissipation

The cement casing improves heat dissipation and mechanical strength, allowing this resistor to operate continuously in demanding environments. Rated for -55C to 155C, it withstands both electrical and thermal stress over long service life.

Axial Lead Mounting

Its through-hole axial lead design allows for easy installation in PCBs, chassis assemblies, and control panels. Commonly used in industrial electronics, load banks, and amplifier output stages.
