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.
