Today's high current power supplies demand high efficiency and accuracy. This can be difficult because typically low resistance values cannot offer low TCR. Stackpole’s CSS2725 is a surface mount four watt all-metal current sense resistor that is now available in resistance values down to 0.2mΩ in 100 ppm TCR.

High efficiency current sensing requires low resistance values to minimise wasted power. As applications downsize, engineers are challenged to find lower resistance values in small case sizes. Stackpole has announced that it now offers the CSSH0805. This all-metal 0805 case size is capable of dissipating up to one watt of power at resistance values 0.5mΩ.

As modern electronics evolve, engineers are challenged to expand functionality in smaller packages. To facilitate this these demands, resistors and other components need to be available in small case sizes without sacrificing performance. Chip resistors with smaller sizes and higher performance are critical to the evolution of portable test and measurement equipment, portable medical electronics, diagnostic devices, and high end portable aud...

Electronic devices that require downsizing or increased functionality may utilise high power surface mount resistors to accomplish this. High power surface mount chip resistors utilise materials designed for the higher temperatures associated with higher power levels. Stackpole's RMCP series is a thick film technology providing higher power capability for a given chip size. 

As the varieties of electronics applications have increased, their voltage requirements have changed in multiple ways. Both higher and lower voltage applications have become common. High voltage resistors to handle the high voltage application requirements can be problematic due to the limited types and capability of most resistors currently available. Stackpole's HVAM series offers working voltage ratings from up to 15KV for the HVAM20 to u...

Electronic content has rapidly increased in a wide variety of markets. For applications that reside in humid or unpredictable environmental locations, resistors with robust performance in humidity and under environmental stress is key. Typical anti-moisture resistors are expensive and have limited availability.

As electronics evolve, the power and pulse requirements have changed higher efficiency electronics and motors mean lower power, voltage, and current requirements. As a result, designs which have traditionally required a carbon composition or wirewound resistor may now be able to use a lower cost metal oxide resistor.

Power supplies and power controls have a wide range of sensing requirements. For applications that require high sensing precision, the element TCR is more important than low resistance values. 

Power supplies and current sensing circuits have requirements that are as wide ranging as the end products they serve. For applications that require low TCR sense chip resistors, yet don’t need extremely low resistance values for high current handling, this can be difficult.

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.

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.

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.

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.

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.

Industrial and commercial power electronics demand robust power supply performance. When high stability and low thermal resistance are important, standard chip resistors may not be the best solution. RMCW thick film wide termination chip resistors with reverse geometry provide terminations on the long sides of the chip, as opposed to the short side terminal for standard chips.

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.
