Series 1 BetaCurve Bare leaded Thermistors
Introduction
The BetaCURVE Thermistor Series I are small epoxy coated devices with solid tin plated lead
wires. The series offers a choice of precision temperature tolerance classifications for a wide
variety of customer applications, such as temperature measurements, temperature indication,
temperature control, and thermal compensation.
The BetaCURVE Series history of "long term" stability and reliability performance have been
demonstrated in critical medical, scientific instrumentation, military/aerospace and industrial
applications.
Thermistor interchangeability has become an important factor for cost efficiency in advanced
thermal performance applications. The need for expensive individual thermistor calibration is not
necessary. The BetaCURVE Series interchangeability means that each device will match the
published Resistance−Temperature Characteristics for a given thermistor and will be within the
specified deviation (tolerance, ie. ±0.1°C, ±0.2°C, ±0.5°C and ±1.0°C) limits over the
temperature range 0°C to 70°C.
