Foil-on-ceramic sense resistors feature resistance values to 0.1 milliohm

October 3, 2022 By Redding Traiger

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

August 18, 2022 By Redding Traiger

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

July 14, 2022 By Redding Traiger

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

July 11, 2022 By Redding Traiger

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 […]

Current-sensing 0.2 milliohm resistors handle 3 W

June 28, 2022 By Redding Traiger

High-efficiency current sensing requires low resistance values. Values less than 1 milliohm can be difficult to find and typically have high TCR. Stackpole recently added a 0.2 milliohm resistance value to its CSNL2512-3W series. The CSNL2512-3W handles 3 watts of power while providing TCR from ±50 ppm for a 1 and 2 milliohm to ±175 […]

Four-terminal current-sense shunt resistors sport improved TCR

June 10, 2022 By Redding Traiger

Current sensing resistors must balance the efficiency requirements of low resistance values, and high current handling with the precision and accuracy requirements of the sensing circuit. But the key requirement of most current sensing circuits is stable performance over temperature. Component TCR is the key measurement parameter for the temperature stability of a resistor. Stackpole […]

Current-sensing resistor handles 7 W

May 17, 2022 By Aimee Kalnoskas

Power electronic engineers continue to push for higher power, lower values, and better precision. Most common resistor technologies cannot adequately meet all three requirements, but Stackpole’s CSS/CSSH Series is able meet these demands in a variety of sizes, power ratings and values. Stackpole’s latest addition is its 3637 high-power shunt. The CSSH3637 is a 7W […]

High current metal shunt for hybrid power sources

May 11, 2022 By Redding Traiger

As power electronics evolve, the requirements for high current, low resistance sensing resistors continue to increase. Emerging applications, such as hybrid power systems, may require high power, high accuracy, and low thermal resistance. These are a difficult combination for many traditional sense resistor technologies. Stackpole’s HCS series provides high power, precise sensing, and low thermal […]

Wide terminal thick-film chip resistors handle up to 3 W

May 3, 2022 By Redding Traiger

Applications for surface mount chip resistors with high power requirements typically mean higher circuit temperatures due to thermal resistance limitations. One of the most common and economical options for reducing the effects of high power is wide terminations. By reversing the geometry of the chip resistor and applying the terminations to the long sides of […]
