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 […]

Thin-film resistors excel in high sulfur, high humidity settings
Environmental stability for thin film resistors has become more important with increased electronic content. Sulfur contamination for film resistors, for example, is becoming a more prominent issue for a wide range of end products. Electronic devices and circuitry may encounter sulfur in the presence of oils, lubricants, gaskets, hoses, and atmospheric gasses in highly industrial […]
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 […]
Precision tantalum nitride chip resistors offer anti-sulfur performance
Applications that require resistors with both environmental stability and high precision have limited options. Nichrome-based thin film resistors have excellent electrical performance and stability but can experience corrosion under prolonged exposure to high moisture environments. Many chip resistors, both thick film and thin film, with screen, printed inner terminations may experience resistance shifts and failure due […]
Anti-sulfur thick film chip resistors feature working voltage up to 75 V
Sulfur contamination for thick film resistors is becoming a more prominent issue for a wide range of end products. Electronic devices and circuitry may encounter sulfur in the presence of oils, lubricants, gaskets, hoses, and atmospheric gasses in highly industrial areas. Finding anti-sulfur resistors can be challenging and finding them with the ideal power 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 […]
Automotive grade thick-film chip resistors offer anti-sulfur performance
Many types of electronic products across a variety of market segments require higher reliability components. Automotive grade resistors offer increased reliability and improved performance without the high cost and limited availability of components procured to established reliability military specifications. Stackpole’s RMCA series is AEC-Q200 qualified and provides excellent long-term reliability. This series is produced on […]
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 […]
Current-sensing 0.2 milliohm resistors handle 3 W
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 […]
