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
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
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 […]
Thick-film chip resistors excel at handling high power levels
The RPC-UP from Stackpole offers 0805 and 1206 size chip resistors with excellent pulse withstanding and high-power ratings. The RPC0805-UP is rated at 0.5W and 400V working voltage and the RPC1206-UP is rated at 0.75W and 500V. Resistance values range from 1 ohm to 1Meg ohm with tolerances from 20% to 0.5% available for some resistance values. The […]
Four-terminal shunt resistor provides low-resistance, high-accuracy current sensing
Stackpole’s CSSK3637 is a four-terminal shunt that provides very low resistance values which have been expanded to 0.5 to 6 milliohms, in tolerances as low as 0.5% and TCR of 50 ppm. In addition, this all-metal shunt has an operating temperature up to 170C, providing excellent stability for a wide range of end products. The […]
SMD zero-ohm jumpers handle over 70 A
Zero-ohm jumpers are widely used in all types of electronic circuits for a wide range of markets and end products. They make circuitry routing easier and simplify manufacturability. However, jumper requirements for higher current levels frequently exceed the capability of general-purpose jumpers, and even some jumpers are classified by the manufacturer as “high current.” Stackpole’s […]
High-current shunt resistors offer a 5-W power rating
Modern electronics utilize current sense resistors for portable power management. As larger and more powerful devices become portable, higher currents and higher power ratings become critical, however, space for any portable electrical device must always be conserved. The HCSM2818 from Stackpole offers a 5-watt continuous power rating to maximize power handling in a given PCB […]
Current-sensing foil-on-ceramic resistors sport 2 milliohm resistance
High efficiency in consumer electronics has become increasingly important. For portable electronics, this means lower resistance values on current sense resistors for battery and power management. Stackpole’s CSRF series is a foil on ceramic carrier chip resistor that is designed for these applications. The CSRF2512 is now available in resistance values down to 2 milliohms. […]
Ultra-high power thick-film chip resistors offer PCB space savings
Today’s electronics devices push the envelope for smaller designs and greater functionality. Stackpole’s RMCP-UP is a high-power thick film chip resistor with very high power ratings for each case size, ranging from 0.2W rated 0402 sizes to 3W 2512 size. These elevated power ratings allow design engineers to use smaller chip resistors to free up […]
High-current jumpers handle up to 7 A
Electronic circuits frequently require zero-ohm jumpers for ease of manufacture or to make trace routing easier. Some of these applications require current handling that exceeds the capabilities of general-purpose or high current jumpers. Stackpole’s HCJ series offers more than double the current rating of comparable high current jumpers. The HCJ current ratings range from 5.8A for […]
