In this post, we discuss the potential measurement errors in sensitive analysis and measurement equipment caused by a mismatch in resistor TCR and how a thick film resistor network may be one possible solution.

Precision resistors are used in a wide range of measurement and analysis equipment. Voltage dividers and precision references are common in such applications with two (or more) resistors utilised to provide a known reference or input voltage

When trying to select the correct thick film resistor it is important to understand why resistors fail under pulse conditions. High energy pulses may occur in a wide variety of applications. They may be predictable or random events. It is important to understand the nature of the pulse event, the application and environmental conditions and select a resistor accordingly.

Thick film resistors fail under pulse conditions because they are unable to dissipate the heat generated in the resistor device by the electrical energy of the pulse.

Heater resistors are used in a wide variety of applications from simple demisting elements in car windscreens to complex medical applications where demand is increasing for custom heater resistors to satisfy the requirements of demanding and diverse medical applications. In this post, we discuss the information required by a specialist resistor manufacturer to design and deliver an application specific heater resistor.

Two of the most common resistor technologies are thick film and wirewound. In this post we compare thick film high voltage resistors with their wirewound competitors discussing the advantages and disadvantages of each.

Thick film high voltage resistors are manufactured by depositing a resistance film pattern onto a flat substrate (usually Alumina). The assembly is then fired at high temperature. The resistor elements are often applied in spiral patterns and consist of metal alloy or oxide particles, functional elements and a glass particle binder.
