Thermistors deliver R25 Values from 100kΩ to 210kΩ 2014

Description:

Boasting enhanced stability for temperature sensing and compensation circuits, the SMD NTC thermistors from Vishay are optimized for heat counters, body thermometers, and other medical applications.

The thermistors provide precise measurements over a wide temperature range of -40 °C to +125 °C, and feature non-standard R25 values that are adapted to the resistivity of the thermistors' stable ceramic material and case dimensions. This last feature preserves the devices' original electrical properties throughout their lifetime for increased accuracy. The devices have an ultra-low ± 0.5% maximum variation in their initial electrical resistance values at +25 °C (R25) after 10,000 hours of operation over the full temperature range.

The devices provide one R25 value per case in the 0402, 0603, and 0805 case sizes. The devices' high R25values from 100 kΩ to 210 kΩ reduce self-heating effects, which could result in false temperature readings.
