Cement resistance has good heat resistance, low temperature coefficient, low noise, high load power, high insulation, and non flammability. Operating environment temperature: -55 ℃~+275 ℃

Cement resistors are usually used in situations with high power and current, including 2W, 3W, 5W, 10W, 15W, 20W, 25W, 30W, 50W, and even higher power. Cement resistors are commonly used in appliances with power levels above 100 watts, such as air conditioners and televisions.

The disadvantage of cement resistance lies in its large volume, high heat generation during use, difficulty in dissipating, and often insufficient precision to meet usage requirements, stability, etc. When high power, small volume resistors, or high precision and fast heat dissipation are required, cement resistors can be replaced with JEPSUN power resistors, which can achieve power of 3W, 20W, 30W, 50W, 100W, or even higher. TO-220 and TO-247 packaging are used, with high precision, strong stability, and fast heat dissipation.

Its advantages and disadvantages:
 1. Features such as shock resistance, moisture resistance, heat resistance, good heat dissipation, and low price.
 2. Completely insulated, suitable for printed circuit boards.
 3. Wrap wires on the porcelain rod and then weld the joints to produce precise resistance values and extend the lifespan.
 4. High resistance values are made using metal oxide film (MO) instead of wire winding.
 5. Excellent heat resistance, low temperature coefficient of resistance, and linear variation.
 6. Durable to short-term overload, low noise, resistance value remains unchanged over the years.
 7. Good explosion-proof performance, providing protection.
