Multicomp Pro Wirewound Resistor 47R 5% 3W

The Multicomp Pro MCKNP series is a robust wire-wound, fixed resistor designed for reliability in electronic circuits. It features a rod-type ceramic body for structural integrity and effective heat dissipation, with tin-plated iron surface steel end caps ensuring excellent solderability and corrosion resistance.

The component is constructed with annealed copper leads that are coated with a tin-lead finish, providing a secure and durable connection point. The entire assembly is protected by an insulated, non-flame paint coating, enhancing its safety and longevity. A key feature of this resistor is its non-inductive winding, making it suitable for AC and high-frequency applications where inductance must be minimised.

Applications

Engineered for demanding environments, this flame-proof resistor offers excellent flame resistance, making it a safe choice for power supply circuits, industrial controls, and automotive electronics. Its AEC-Q200 qualification confirms its suitability for automotive applications where component reliability is critical. The 3W power rating allows it to handle significant electrical loads with stability.

For installation, the terminal leads are designed to be bent 90 degrees approximately 6mm from the resistor body and can be rotated 360 degrees about their axis, offering flexibility during the PCB assembly process. This resistor can also be joined by welding, providing an alternative secure mounting method. It operates effectively at an ambient temperature of up to 70°C.
