FEATURES
•Top and bottom surface terminations
•High-density monolithic ceramic construction
•Allows design flexibility for use with hyprid circuitry
•Model W is a thermistor die with silver conductors fired on
the top and bottom surfaces. The bottom surface can be
reflow soldered or conductive epoxied directly to a
substrate bonding pad and the top surface wire bonded to
comlete the circuit connection.
