Product Description
Product Overview
The Littelfuse MITI-3V1 is an ultra-miniature, normally open reed switch designed for high-reliability applications. It features a 7mm long glass envelope capable of switching 170Vdc at 10W, with a high insulation resistance of 10 ohms minimum and low contact resistance of less than 150 milliohms. This hermetically sealed switch requires zero operating power and is ideal for space-constrained designs, including reed relays, security systems, metering, and mobile phones. A surface mount version, the MISM-3V1, is also available.
