Stackpole's AEC qualified RTAN series utilises tantalum nitride technology to provide moisture proof precision chip resistor performance. The RTAN film passes biased humidity testing at 85oC, 85% relative humidity, and ten percent bias with very little shift in resistance.

As electronic devices continue to evolve, finding resistors that have higher power ratings in a given package size are more and more important. However, higher power resistors can often generate significantly more heat than resistors with standard power ratings.

High efficiency current sensing is commonly done using low resistance value resistors. However, as resistance values are reduced, the measurement error due to lead resistance becomes significant. For applications requiring high efficiency with the best possible temperature accuracy, four terminal metal element current sensing products are the ideal choice.

Stackpole's RMCS series now offers a 2W power rating in a 2512 chip resistor size as the RMCS2512 ... -HP. This option doubles the standard 2512 power rating and allows for the RMCS-HP to be used for higher power applications that may have used a different technology previously.

Applications that experience pulse events require special consideration for selecting resistors. General purpose thick film chip resistors have variable pulse handling depending on calibration trim length. As a result, their pulse performance can be unreliable.

Zero ohm current jumper chip resistors provide an essential function for circuit design. They make trace routing easier for single layer PCB's, are easier to assemble in mass production and less costly than jumper wires. Some designs however require more robust current handling than general purpose thick film chip jumpers.

Current sensing for high efficiency can be done easily and economically using current sense resistors. As resistance values are reduced, the measurement error due to lead resistance becomes more of a problem. For applications desiring high efficiency with the best possible temperature accuracy, four terminal current sensing products are a good choice.

The HCSM2818 from Stackpole is only marginally larger than a standard 2,512 size chip but offers a 5W continuous power rating to maximise power handling in a given PCB area. The AEC compliant HCSM2818 offers one and five percent resistance tolerances in resistance values of four, five, ten, 15, 20, and 25 milliohms. TCR ranges from 200ppm for the four and five milliohm values to 75 ppm for the values 10 ppm and higher.

Stackpole has announced that it offers engineers a solution for these applications with its MLFA Series. The MLFA is an AEC-Q200 compliant MELF resistor that offers exceptional electrical and environmental performance with low thermal resistance.

Applications for thick film chip resistors which are 100% lead free without exemption continue to expand. Finding resistors for those applications can be challenging since there are few options currently available.

Stackpole electronics has announced that it has the CSRF0603 foil on ceramic carrier chip resistors in stock in values as low as 2.5 mΩ, combining small size and low resistance values for maximum electrical and dimensional efficiency.

Engineers face challenges when designing electronics that require a high voltage axial leaded resistor because of limited options and high cost. Stackpole's HVA series axial leaded high voltage resistors provide high voltage handling in a cost effective, compact thru-hole package.

For high pulse voltage, anti-surge axial leaded resistors such as Stackpole’s ASR / ASRM series, offer stable electrical and environmental performance, good pulse handling, and have lower inductance than wirewound resistors. The ASR / ASRM can handle pulse voltage discharges from one to ten kilovolts and are rated for working voltages of up to four kilovolts depending on size and resistance value.

Stackpole’s RMCP is a thick film chip resistor with high power capability and is now available in resistance values up to ten megohm. This expanded resistance range and high power handling make the RMCP useful for a wider range of general purpose application requirements and circuit functions.

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

Stackpole recently enhanced their RNCF0402 size Nichrome precision chip resistor, increasing the power rating to 0.1W for resistance values from 4.7 ohms to 255K for 0.1% tolerances and 25 ppm TCR. This improved power rating allows the RNCF0402 to be used for applications that may normally require an 0603 or 0805 size chip resistor enabling downsizing and making added functionality much easier.

Modern electronics have become more complex and their requirements more precise. For those applications that require low TCR, good pulse handling and low self-heating, a MELF resistor is often the best choice.

Stackpole has released the NWWP series axial leaded wirewounds that provide good anti-surge characteristics in a non-inductively wound design. The Ayrton-Perry winding greatly reduces inductance to a fraction of what a standard winding would provide while the robust wire design maximises element mass for exceptional energy handling.

Power supplies and power controls have a wide range of sensing requirements. For applications that require high sensing precision and high power where the element TCR is more important than low resistance values, the CSRT2512-UP offers a 3.5W rated current sense chip resistor in a package that normally only allows for one or two watts.

Power electronics that utilise current sensing resistors for power control have a wide range of typical requirements. For those applications that require high power handling with low self-heating and high surge currents, the HCS high current SMD shunts from Stackpole are a good choice.
