Thermal Resistors FAQ
What is the typical lifespan of thermal resistors?
Our thermal resistors typically last 10+ years under normal operating conditions. The lifespan depends on operating temperature, exposure to harsh environments, and current load. When operated within specified parameters, thermal resistors maintain their accuracy for extended periods with minimal drift.
How do thermal resistors differ from RTDs?
Thermal resistors (thermistors) generally offer higher sensitivity and faster response times than RTDs (Resistance Temperature Detectors), making them ideal for applications requiring precise temperature measurement in small ranges. RTDs typically provide better linearity over wider temperature ranges but have lower sensitivity.
Can thermal resistors be used in high-vibration environments?
Yes, our ruggedized thermal resistor models feature reinforced construction with vibration-resistant designs that maintain stable operation in high-vibration applications up to 10G. Special epoxy coatings and strain-relief terminals prevent micro-fractures that could affect performance in demanding environments.

More Thermal Resistors Questions
What maintenance do thermal resistors require?
Thermal resistors require minimal maintenance. Periodic calibration checks (annually for critical applications) ensure ongoing accuracy. Visual inspections for physical damage or corrosion are recommended, especially in harsh environments. Most thermal resistors function maintenance-free for their entire service life.
Can thermal resistors be customized?
Yes, we offer customization options for thermal resistors including specific resistance values, lead lengths, connector types, housing materials, and special coatings. Custom thermal resistors typically require a minimum order quantity and extended lead time for design and testing.
How accurate are thermal resistors?
Our standard thermal resistors offer ±0.1°C accuracy at 25°C, with precision models achieving ±0.05°C. Accuracy varies with temperature range - typically ±1°C at extremes of the operating range. For maximum accuracy, we recommend characterization over your specific temperature range of interest.
