THIN-FILM THERMISTOR Russian patent published in 1998 - IPC

FIELD: electronic engineering; temperature sensors. SUBSTANCE: thermistor has insulating substrate carrying thin-film structure of two resistors (main and additional ones) covered with shielding material and connected to contact pads. One pad is common for both main and additional resistors built up of meanders whose materials have different resistivity and at least one adjusting section. Thermistor metal leads are located on one side of substrate and fixed by welding or soldering to at least two contact pads. Contact pad common for main and additional resistors is formed by fixed soldered joint of main and additional resistors mounted in direct proximity of contact pads. EFFECT: improved accuracy and stability of thermistor characteristics. 3 dwg
