WEET SQP High Power Rate 30W and 50W Available for Audio Crossover Applications

Ceramic insulated power type wire wound resistors are often referred to as cement resistors. It is widely used in computers, televisions, instruments, meters, and speakers. Cement resistors are made by winding resistance wires, usually with high power and large external dimensions. Therefore, it can be easily distinguished from its appearance combined with power and model. In terms of power, it is divided into specifications such as 2W, 3W, 5W, 7W, 8W, 10W, 15W, 30W, 20W, 40W, 50W, etc. The common models on the market are RX27-1, RX27-3 (3A, 3B, 3C), and RX27-4 (4V, 4H). The model of WEET is SQP. Below is WEET SQP 30W and 50W picture for your kind view, thank you.

The cement resistor adopts an industrial high-frequency electronic ceramic shell, which has good heat dissipation and excellent insulation performance. Its insulation resistance can reach 100MR, and it also has excellent flame retardant and explosion-proof properties. The resistance wire is made of alloy materials such as constantan, manganese copper, nickel chromium, etc., which have good stability and overload capacity. The resistance wire and the solder pin lead are crimped together. In the event of a load short circuit, it can quickly melt at the crimping point, providing protection for the circuit.

Cement resistors have various shapes and installation methods, and can be directly installed on printed circuit boards or independently installed and welded using metal brackets
