The OHMITE RX-1M series resistors are precision components engineered for applications requiring exceptional accuracy and stability. These hermetically sealed resistors utilize metal oxide resistive elements and are vacuum sealed in a glass envelope, making them suitable for ultra-high vacuum environments. They offer improved temperature and voltage stability and are designed to maintain high performance over extended periods. Applications include medical instrumentation, current pulse limiters, avionics, and ultra-high vacuum systems. Proper handling and cleaning with isopropyl alcohol are recommended to prevent contamination and maintain resistance value.
