As design engineers continue to push the miniaturization of electronic devices while maintaining or increasing functionality, there is a corresponding need for smaller and more precise electronic components, such as chip resistors. If a precision application requires both small size and high-power handling, finding suitable precision resistors may be challenging. Stackpole recently increased the power […]

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 […]
