Industrial electronic controls and instrumentation pose challenges to designers. Industrial applications require high power handling and stability in harsh environmental environments, but also may need precision tolerances and TCRs; a difficult combination for film chip resistors. It is difficult to achieve high power ratings with thin film resistor technology normally used for precision requirements. Stackpole’s […]

What you need to know about potentiometers
From analog volume controls to precision measurement devices, potentiometers offer engineers a reliable means of achieving control and precision in electrical systems. Commonly referred to as “pots,” these devices are essentially resistors featuring a mechanical adjustment mechanism that allows for manual change of their resistance. Their basic principles and concept date to the 1800s with […]
Thin film precision resistors offer full capability up to 80°C, operation up to 170°C
Automotive and industrial applications may have harsh environmental requirements for resistors. When those requirements include high-temperature capability and high precision, options are limited. Stackpole’s RNHT thin film precision resistors offer full power capability up to 85 degrees C and operation up to 170 degrees C. The automotive grade RNHT is AEC qualified and offers a […]
CM series carbon matrix resistors
RCD Components, under the iNRCORE Family of Brands, is launching a new line of carbon matrix resistors comparable to the now unavailable Allen Bradley and other aftermarket Carbon Composition parts that have been marked end-of-life. The line enhances stability and reduces the common moisture-related issues of the Carbon Composition line, CC series. Ideal for Hi-Rel, Military, […]
Improved TCR on thin film current sense chip resistors
Power supplies and current sensing circuits have requirements that are as diverse as the end products they serve. Some applications, for example, need low TCR without requiring low values associated with metal alloy resistors. It can be challenging to find such a resistor. Thick film technology is generally used for higher sense resistor values, but they have poor […]
Current sense resistor provides overcurrent protection, monitoring, and control
Littelfuse, Inc. announced the launch of its new Current Sensing Resistor (CSR) family. These new CSRs offer a more cost-effective solution for measuring current within circuits, enabling voltage monitoring, control, and power management of functions such as battery charging and motor speed, while also providing overcurrent protection. The Current Sensing Resistors Series is a game […]
SMD current shunt resistors offer resistance values as low as 0.2 mΩ
Stackpole’s popular HCS series raised element SMD current shunt resistors to offer resistance values as low as 0.2 milliohm and power ratings up to 10W, which allows the HCS to sense currents up to 224 amps. In addition, TCR for the HCS is ±50 ppm for a wide range of values which ensures accurate sensing […]
