Cement Resistor 5W Assortment Kit — Multiple Values, Wirewound
A comprehensive 5W cement wirewound resistor assortment kit in multiple resistance values from 1Ω to 100Ω. Cement resistors are high-power wirewound resistors encased in a ceramic cement body for excellent heat dissipation — capable of handling 5 watts of continuous power without damage. Essential for dummy loads, power supply testing, motor braking resistors, and high-current limiting applications where standard 1/4W or 1/2W resistors would burn out instantly.
Kit Contents
- Resistance values: 1Ω, 2Ω, 3Ω, 4.7Ω, 5Ω, 6.8Ω, 10Ω, 15Ω, 20Ω, 22Ω, 33Ω, 47Ω, 51Ω, 68Ω, 100Ω
- Multiple pieces per value
Key Specifications

Why Cement Resistors?
- ✅ 5W power rating — handles high-current applications that destroy standard resistors
- ✅ Cement encapsulation — excellent heat dissipation, flame-retardant
- ✅ Wirewound construction — stable resistance under high temperature and power
- ✅ Assortment kit — multiple values for different load requirements
Power Dissipation Guide
P = V²/R or P = I²×R. Example: 10Ω at 12V = 14.4W — use three 5W resistors in series or add heatsinking.
Typical Applications
- Battery and power supply dummy load testing
- Motor braking resistor
- High-current limiting resistor
- Electronic load resistor bank
- LED driver current limiting (high power)
- Voltage divider for high-voltage sensing
