Refined with high-performance ceramics, cement and high-quality metals, it ensures excellent anti-vibration, moisture-proof and heat-insulating properties. Its robust structural design, coupled with excellent heat dissipation characteristics, makes the resistor a highly reliable choice as it maintains stable performance and does not deteriorate easily under long-term operation.
Cement resistors provide stable resistance values with tolerances of only +5 per cent or -5 per cent, ensuring accurate current and voltage control. Their temperature coefficient is as low as 250ppm/degree Celsius, which ensures that the resistance value varies very little over the operating temperature range of -55 degrees Celsius to 155 degrees Celsius, guaranteeing the stability and accuracy of equipment operation.
The body size of each resistor is 0.9x0.39x0.37 inch (about 22.8x10x9.4mm). The small size makes it easy to install in a compact space, and accurate resistance values can be obtained directly after soldering without the need for additional calibration, which is extremely convenient for engineers and DIY enthusiasts.
Widely used in all kinds of high-end electronic equipment, such as air-conditioning systems, power adapters, computer motherboards, televisions, automotive electronic systems, audio equipment, measuring instruments and audio systems, etc., as a key electrical protection and signal conditioning components, to enhance the overall performance and stability of the equipment.
Each pack contains 10pcs of ceramic cement resistors to ensure your needs in a large number of applications or spare parts replacement. We insist on using high quality raw materials and paying attention to each production process to ensure that each resistor has a low temperature coefficient and good explosion-proof to cope with sudden overloads, reduce noise and prolong service life.
