Cement Resistor 5W Assortment Kit — Multiple Values, Wirewound

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.

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
