Vishay Dale
NTC Thermistors, Surface Mount Chip
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
complete the circuit connection.
