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 […]
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, […]
Zero-ohm jumpers handle up to 158 A
Zero-ohm jumpers are commonly used in a wide range of markets and end products. They make circuitry routing easier and simplify manufacturing. Jumper requirements for higher current levels frequently exceed the capability of general-purpose jumpers. The maximum current rating for thick film general-purpose jumpers is only 3 amps and high current thick film jumpers typically […]
Foil-on-ceramic sense resistors feature resistance values to 0.1 milliohm
Current sensing for a wide range of products and applications requires both low and high resistance values with high stability, reliability, and low TCR. For devices that need somewhat higher resistance values, high current handling, low TCR, and high stability, finding cost-effective solutions can be challenging. Film-type resistors will not have high current handling, and […]
High-current SMD shunt resistors sport 0.1 milliohm resistance
Modern electric power systems continue to push the power envelope. Power electronics for electric vehicles often use a high-power low resistance shunt resistor which can be expensive and difficult to find. Stackpole’s HCS high current SMD shunt resistors are now available in a 0.1 milliohm resistance value in a 10W, 5930 chip size. The HCS has an […]
Current-sense shunt resistor offers 0.5 milliohm resistance, 3-W power rating
High-efficiency current sensing requires low resistance values. However, lead resistance may cause inaccuracies in sensing measurement for ultra-low resistance values. Four terminal Kelvin connections with separate sense and current flow connections eliminate the detrimental effects of lead resistance yielding a very accurate measurement of the power delivered. Stackpole’s CSSK3637 is a four-terminal device offering resistance […]
High-power sense resistors feature high temperature stability
For current sensing applications requiring high efficiency, low resistance values are required. Typically, high power sense resistors are very large and have TCR in the 200 to 400 ppm range. Stackpole’s HCSM2818 is rated at 5 watts and now provides a 2 milliohm resistance value with a TCR of 100 ppm. This ensures the HCSM2818 is stable at […]
