(Re)designing resistors with computational fluid dynamics
Here, Damiano Natali, research and development engineer at power resistor manufacturer Cressall, explains how Computational Fluid Dynamics (CFD) improves product designs that have stayed much the same for decades.
High current conductive polymer electrolytic capacitors
Panasonic Industry Europe has introduced the new surface-mount type ZF series of Conductive Polymer Hybrid Aluminium Electrolytic Capacitors. Being able to endure high temperatures of 150°C for up to 1.000 hours, the new capacitors benefit from a high withstand voltage of 25 to 63V and a low leakage current of (0.01 CV or 3µA). The nominal capacitance range is 33 to 270µF.
Chip resistors show durability in harsh environments
Panasonic's ERJ-UP3 series of anti-sulphureted thick-film chip resistors, anti-surge type come in an 0603-inch case size.
CSRF0508 size termination current sense chip resistor
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.
Stackpole launches five watt current sense chip resistor
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.
Mission-critical resistor uses proprietary foil technology
The new VPG Foil Resistors Model 303337 ultra-high precision military-and space-grade resistor is on sale at New Yorker Electronics.
Extended range adds to tantalum capacitors applications
Wet Tantalum Capacitors from Vishay Sprague Capacitors have had their range extended to cover Industrial, AMS and Refinery applications – as indicated by the extended ratings.
Automotive-grade resistors offer TCR down to ± 2 ppm/K
Vishay Intertechnology has extended its TNPU e3 series of Automotive Grade ultra-precision thin film flat chip resistors with lower temperature coefficient of resistance (TCR) down to ± 2 ppm/K in the 0603, 0805, and 1206 case sizes.
RC Networks absorb spark discharges and induced noise
The complete series of Electrocube RC Networks ‘Arc-Suppressing’ Resistor-Capacitor (RC) Circuits is on sale at distributor New Yorker Electronics.
Electrolytic capacitor saves space, weght and costs
New Yorker Electronics is now marketing and selling a new Ultra-Low-Profile Aluminum Electrolytic Capacitor from Cornell Dubilier Electronics (CDE).
