NTC Thermistors, Radial Leaded and Coated
FEATURES
• Small size - conformally coated
• Wide resistance range
• Available in 7 different R-T curves
• Available in point matched tolerances down to
1 % and curve tracking precision down to
± 0.2 °C
• Material categorization: for definitions of compliance
please see www.vishay.com/doc?99912
APPLICATIONS
Temperature measurement, sensing and control in
industrial, consumer and telecom applications. For
on-board sensing or for accurate remote sensing in metal
probes or housings.
DESCRIPTION
Models T, M, and C are conformally coated, leaded
thermistors. The coating is baked-on phenolic for durability
and long-term stability. Models M and C have tinned solid
copper leads. Model T has solid nickel wires with Teflon
®
insulation.
