Current sensing resistors that operate at high power can experience significant self-heating. This self-heating can cause error in measurement if the sense resistor has high TCR. Stackpole's CSM2512 current sense resistor offers a metal element with TCR now improved to 50 ppm.

Applications requiring power control and monitoring are becoming more demanding. Specifically, added functionality and higher power requirements require higher efficiency, high accuracy, and higher power handling. Stackpole’s five watt current sense chip resistor could be the solution.

Precision chip resistors with tolerances of 0.1% or tighter and TCR of 25 ppm or better have become more common due to the wide range of applications and end products requiring such resistors. However, some of these applications require circuit operation in high humidity environments.

Power supplies and controls face an increasing level of surge requirements from regulatory bodies as well as internal design requirements. Higher power ratings and better pulse withstanding are critical. Discover the RPC2512-HP 2W pulse withstanding chip to help with these challenges.

Applications requiring power control and monitoring are becoming more demanding. High power sensing with low TCR and low thermal resistance are important when power electronics have size constraints.

High voltage applications frequently require high voltage resistors with high accuracy for voltage division, monitoring and control.Some applications with more moderate working voltages may experience high voltage surges which may damage general purpose chip resistors, Stackpole is providing a range of solutions.

There is an on-going trend to smaller, portable and more functional devices in the consumer electronics world. This is particularly true in the current sense chip resistor market where power control architectures are being downsized even as the functionality is being enhanced.

Low resistance values are important for high efficiency current sensing in that lower values mean less wasted power on the current sensing measurement itself. But sensing low resistance values becomes challenging because of lead resistance.Using a four terminal shunt resistor eliminates the detrimental effects of lead resistance on the current sensing measurement operation.

Stackpole has added a two milliohm resistance value to its popular CSS0603 Series. The ultra-precision 0603 metal foil is rated at 0.33W of power and the two milliohm resistance value has a TCR of ±150ppm with tolerance capability as low as one percent.

Stackpole Electronics has announced the release of the CML Series MLCC capacitors. The CML offers a wide capacitance range from 0.1pF up to 100uF in voltage ratings from ten to 100V. Available in C0G dielectric for exceptional stability and accuracy and no ageing effects, X7R and X5R for broad capacitance range and higher capacitance capability, and Y5V for cost effective high capacitance solutions with the best volumetric efficiency.
