Thermometrics Type PRE/K PTC Thermistors consist of thin-film platinum resistance elements. A ceramic substrate supports a structured platinum layer covered with glass. The connection lead contacts are shear force resistant. They are especially suited for surface measurment with applications in the automotive and domestic appliance industries with many options for customization.
Applications
- Especially suited for surface measurement
- Installation on printed circuit boards
- Applications in the automotive and domestic appliance industries
- Resistance elements selected in tolerance groups for calorimetry
- Large quantity applications
Features
- Small dimensions available
- High electrical insulation is guaranteed by non-conductive edges and sides
- Short response times
