Ohmite 850F25K Metal Housed Axial Resistor
The OHMITE 850F25K resistor is a robust, axial-lead wirewound resistor encased in an aluminum housing. This construction provides exceptional stability during operation and allows for secure mounting to chassis surfaces. The metal housing also acts as a heat sink, enabling the resistor to exceed power ratings specified in MIL-R-18546. Ideal for applications requiring high reliability and performance in demanding environments, such as industrial equipment, automotive systems, and military applications. The resistor's design ensures consistent performance and longevity, contributing to the overall reliability of the system it serves.
