“MELF”
Surface Mount NTC Thermistors
U.S. Sensor’s NTC LL-31 and LL-41 “MELF” style glass encapsulated
surface mount thermistors are manufactured using super stable NTC chips
which are hermetically sealed in a glass package. The result is an extremely
reliable surface mount package which is capable of withstanding the most
severe environmental conditions. Tape and reeling for use with automatic
insertion equipment is available.
