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 […]

Current shunt resistors handle 5 W in space-efficient 2818 package
Power management applications for frequency converters, inverters, and hybrid power modules demand high power with environmental and electrical stability. While high power shunt resistors for current sensing are becoming more readily available, there is normally a tradeoff between high power and stable performance to achieve the higher power rating. Stackpole’s HCSM utilizes a metal element and […]
All-metal current-sense chip resistors feature 1-W power rating
IoT and Robotics require high efficiency and small size to maximize functionality. For current sensing, this means high power in small case sizes and low resistance values. The CSSH0805 from Stackpole is an all-metal chip resistor with a 1W power rating, resistance values down to 0.5 milliohms, and TCR ranging from 50 ppm to 100 […]
Ultra-precision current-sense chips feature resistance range to 80 mΩ
The CSSH2512 from Stackpole is an all metal current sense chip resistor capable of precision tolerances as low as 0.5% and TCR as low as 15 ppm. The resistance range for the 3-W 2512 size chip has been expanded and now spans from 0.5 mΩ up to 80 mΩ. The high precision combined with the […]
Keys to understanding resistor specs
The specification process for resistors involves more than just allowing for tolerance bands. Voltage, power, and temperature ratings can interact in ways that can degrade circuit reliability. Kory Schroeder, Stackpole Electronics, Inc. Although not a complex component, resistors have specifications that can be confusing, misleading, and misinterpreted. When specifying performance qualities, it is important to […]

Stackpole’s RV Series of radial leaded metal oxide varistors is available in a wide range of disk sizes and working voltages designed for general purpose overvoltage protection. The RV Series is UL1449 certified and offers disk sizes from 5mm up to 20mm with peak current ratings up to 18,000 amps and energy handling up to […]
RNCF Series Expands 0201 Size Resistance Value Range
Stackpole recently expanded the resistance value ranges of the 0201 chip size of the RNCF Series of precision thin film chip resistors. Resistance values from 49.9 ohm to 33K ohm are now available in tolerances as tight as 0.5% and TCR as low as 25 ppm. With the proliferation of consumer electronics and the desire […]
0201 size chip resistor offers a 0.063W power rating
The RMCP Series from Stackpole is a thick film chip resistor series with high power ratings for a given chip size. Stackpole recently added an 0201 size chip resistor with a power rating of 0.063W while the usual power rating for this size is 0.050W. This high power capability allows the RMCP0201 to be used […]
MELF resistor technology provides cooler operating temperatures at full-rated power
Stackpole’s MLF / MLFM is a series of metal film, surface mount MELF resistors. The MELF technology provides cooler operating temperatures than flat chip resistors at full rated power. For example, the MLFM1 will typically run more than 70 degrees C cooler than the equivalent 1W 2512 size flat chip resistor and has a smaller […]
0603 X 4 chip arrays Now AEC-Q200 qualified
Stackpole has completed AEC-Q200 testing for the RACF and RAVF Series thick film chip resistor arrays in its most popular size, the 0603 by 4 resistors. Per AEC-Q200, these chip resistor arrays must have an operating temperature range of -55 degree C to +150 degree C and survive a wide range of electrical and mechanical […]
