Stackpole introduces the RMEA Series, an automotive grade chip resistor that is not only fully lead-free but also AEC-Q200 qualified and anti-sulfur. Automotive grade chip resistors adhere to higher materials and process standards as well as 100% AOI to ensure the consistent performance and long-term reliability that general-purpose chip resistors cannot guarantee. The RMEA is […]

High-power, thin film chip resistors withstand harsh environments
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 […]
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 […]
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 […]
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 […]
Bare element shunt resistors help lower thermal stress of PCBs
Current sensing for motor control applications often requires robust current handling and the lowest possible PCB temperatures. Unfortunately, high current or overload current handling typically means higher PCB temperatures. One cost-effective and popular solution to these requirements is a raised bare element sense resistor. The elevated bare element yields PCB temperatures of 30% to 40% […]
Resistor series tackle surges up to 10 kV
High-voltage applications such as HVAC controls, appliance and white goods controls, metering, automation, medical devices, digital storage, and surge protection devices typically require resistors with a high working voltage that may be challenging to find. If the applications are low current or low energy, film resistors are an ideal technology. The ASR / ASRM series […]
Metal film low-resistance chip resistors available in 0.25 W up to 2 W for power control applications
Applications such as industrial and automotive power control require low resistance values, high power ratings, and resistance to sulfur contamination. Thick film chip resistors are not typically sulfur resistant, especially in higher power ratings, and many high-power resistor series do not offer values below 1 ohm. Stackpole’s CSRT-AS series offers low resistance values, anti-sulfur performance, […]
Precision thin-film resistors offer ±0.01% tolerances, ±2ppm TCRs
With the proliferation of electronics in nearly every market sector, there is an increasing need for precision resistors. For markets such as medical instrumentation and control, industrial and automotive controls, communications, and test & measurement, these precision resistors must maintain electrical and environmental stability long term. Stackpole’s RNCF series of precision thin film resistors meet these […]
Automotive-grade chip resistors excel at handling pulses
High-reliability chip resistors can be more difficult to find and even more so when there are pulse handling requirements. Typically, the manufacturing process for thick film chip resistors allows for variation in the calibration trim, leading to variation in pulse handling performance. Stackpole’s recently released RPCA series addresses all these needs. The RPCA has limited to […]
