Power supply designers are constantly faced with thermal challenges, especially as power levels continue to rise. Many methods of heat reduction are impractical from a size, layout, or cost standpoint. Thermal jumpers offer a small size and low-cost option to lower PCB temperatures with simple implementation. Stackpole’s TMJ series is a surface-mounted electrically isolated component […]

Bare element shunt resistors help lower thermal stress of PCBs
Current sensing for motor control applications often requires robust current handling and the lowest possible PCB temperatures. Unfortunately, high current or overload current handling typically means higher PCB temperatures. One cost-effective and popular solution to these requirements is a raised bare element sense resistor. The elevated bare element yields PCB temperatures of 30% to 40% […]
Precision thin-film resistors offer ±0.01% tolerances, ±2ppm TCRs
With the proliferation of electronics in nearly every market sector, there is an increasing need for precision resistors. For markets such as medical instrumentation and control, industrial and automotive controls, communications, and test & measurement, these precision resistors must maintain electrical and environmental stability long term. Stackpole’s RNCF series of precision thin film resistors meet these […]
Automotive-grade chip resistors excel at handling pulses
High-reliability chip resistors can be more difficult to find and even more so when there are pulse handling requirements. Typically, the manufacturing process for thick film chip resistors allows for variation in the calibration trim, leading to variation in pulse handling performance. Stackpole’s recently released RPCA series addresses all these needs. The RPCA has limited to […]
Thin-film resistors excel in high sulfur, high humidity settings
Environmental stability for thin film resistors has become more important with increased electronic content. Sulfur contamination for film resistors, for example, is becoming a more prominent issue for a wide range of end products. Electronic devices and circuitry may encounter sulfur in the presence of oils, lubricants, gaskets, hoses, and atmospheric gasses in highly industrial […]
Precision tantalum nitride chip resistors offer anti-sulfur performance
Applications that require resistors with both environmental stability and high precision have limited options. Nichrome-based thin film resistors have excellent electrical performance and stability but can experience corrosion under prolonged exposure to high moisture environments. Many chip resistors, both thick film and thin film, with screen, printed inner terminations may experience resistance shifts and failure due […]
Anti-sulfur thick film chip resistors feature working voltage up to 75 V
Sulfur contamination for thick film resistors is becoming a more prominent issue for a wide range of end products. Electronic devices and circuitry may encounter sulfur in the presence of oils, lubricants, gaskets, hoses, and atmospheric gasses in highly industrial areas. Finding anti-sulfur resistors can be challenging and finding them with the ideal power and […]
Automotive grade thick-film chip resistors offer anti-sulfur performance
Many types of electronic products across a variety of market segments require higher reliability components. Automotive grade resistors offer increased reliability and improved performance without the high cost and limited availability of components procured to established reliability military specifications.
