Thermosensitive

Here at Rhopoint Components we offer a range of highly accurate, through-hole and surface-mount thermosensitive resistors from Alpha Electronics. These ultra-precision resistors utilise metal foil technology to achieve resistivity values changing linearly (or almost linearly) as the temperature changes, which makes them a perfect choice for use in cold junction references for thermocouples, temperature compensation and temperature sensing applications. The Alpha thermosensitive resistors are generally available in any resistance value within a given range and with a choice of different tolerances, while the most popular values are available from stock for quick delivery.
