TTElectronics - Welwyn WRM0204C22RFI MELF Resistor

The WRM Series MELF resistors are high-reliability, Pb-free components designed to handle predictable pulse loads and high thermal stability. These resistors feature TCR values down to 5 ppm/°C and tolerances as tight as 0.1%. They are suited for precision applications requiring stable performance over a wide temperature range, with robust construction including a ceramic body, metal film, and tin-plated termination caps. Their compact size makes them ideal for high-density circuit boards in advanced electronics and industrial equipment.
