Chassis Mount Resistors, UAL25-10RF8 Application Field and Working Principle Chassis Mount Resistors (CMR) are electrical components specifically designed to provide electrical power dissipation in a manageable and regulated form. Unlike regular resistors, CMR’s are designed and constructed to withstand higher temperatures and steady-state currents. CMR’s also provide adequate physical integrity to support the mounting of resistive materials on either side of a chassis or circuit board. The CMR Chassis Mount Resistors include a variety of resistor types including Axial Resistor, Lead-in-Wire, Radial Resistor, Surface Mounted Resistor, and Through-Hole Resistor.The UAL25-10RF8 is a CMR sold under the “Through-Hole Resistor” category. It is a three-terminal THR resistor and as an SMD resistor, it is comprised of a leaded resistor. The resistor has a lead-in-wire make contact with the leads of the THR on two terminals, while the two pins from the leaded resistor connect to the THR leads on the third terminal. The UAL25-10RF8 has a power rating of 0.25W and a resistance range of 10Ω-220kΩ. It is a ±5% tolerance model, with a temperature range of -25°C to +75°C (operating) and 0°C to +75°C (storage). The component is UL recognized, RoHS compliant, and is available in several optional insulation constructions.The UAL25-10RF8 is suitable for use in automotive, HVAC, electronic instrumentation and automation, telecommunications, computer peripherals, and consumer audio equipment. User applications for this CMR resistor include gain and signal level control, LED lighting, line matching, voltage and current regulation, audio input, power supply protection, EMI/RFI interference prevention, and protection against over-voltages in motor control circuits. The most important working principle of the UAL25-10RF8 is that it provides electrical power dissipation in a consistent and accurate manner. By using a combination of heat sink and resistor body, two-dimensional thermal resistance can be achieved, which increases heat dissipation in the whole system. A further advantage of CMR resistors is that the resistor’s decreased overall size will generate less heat, thus allowing for a higher power rating for the application. In addition to the above working principles, the UAL25-10RF8 also includes safety design features including an anti-arcing/flashover protection feature that keeps the resistor case safe from arcing or flashover. This feature is designed to provide more reliable temperature control and higher current-carrying capabilities, as well as lower power consumption levels and extended resistor life. The increased reliability of CMR resistors is achieved by using thicker insulation layers, and special materials like high-temperature ceramic discs or PTC components. Overall, the UAL25-10RF8 CMR resistor provides an efficient way for users to dissipate electrical power in a consistent and accurate manner. With its compact size, combined with its impressive performance and reliability features, the UAL25-10RF8 provides the perfect solution for a wide variety of user applications.
