DC current shunt resistor line expanded up to 10,000 A
Riedon, a specialist manufacturer of cutting-edge power and precision resistors, has expanded its portfolio of precision current shunts to provide one of the broadest range of current ratings available today. Responding to increases in the output levels from renewable energy sources, higher capacity batteries that require shorter charging times, and the widespread electrification of heavy […]
All-metal current sense chip resistors offer high efficiency power management
Stackpole offers low-value resistors constructed with metal foil technology. This precision design allows Stackpole to achieve tolerances down to 0.5%, TCR’s of 50 ppm TCR in resistance values down to 0.25 milliohms. These low resistance values are ideal for power management applications where high efficiency is a priority allowing design engineers to dissipate less power […]
Metal-foil-on-ceramic-chip resistors sense 1 to 10 A
TT Electronics launched the MFC series of metal foil chip resistors for current sensing duties in power electronics applications. The resistors’ small size makes them an ideal choice for designers of highly compact power conversion circuits in industrial and medical applications. Providing a combination of high power density, tolerance of surge conditions and stability, the […]

Low-ohm anti-sulfur current sense resistors carry 0.66-W power ratings
KOA Speer Electronics introduces the SR73-RT, a low resistance anti-sulfuration chip resistor. SR73-RT current sense resistors offer excellent anti-sulfuration characteristics due to the use of a special high sulfuration proof inner top electrode material and are designed for use in harsh environments with a high level of sulfur contamination. SR73-RT current sense resistors deliver low […]
2-W fusable wire-wound power resistors save PCB space
TT Electronics, a global provider of engineered electronics for performance critical applications, today launched its ULWP2R range of fusible wirewound resistors. By combining the functions of a fuse and a line input resistor in a single, vertical radial formed component the resistors save valuable PCB space. The UL recognised, 2W rated power resistors are aimed […]
Transparent silver could advance touchscreen technology
Fans of the sci-fi franchise Star Trek may recall a scene in the 1986 film Star Trek IV: The Voyage Home that mentions a make-believe material called transparent aluminum. A real-world version of it eventually emerged from Oxford University where researchers created a ceramic alloy (officially called Aluminum Oxynitride or ALON) by fusing aluminum, oxygen […]
RNCF Series Expands 0201 Size Resistance Value Range
Stackpole recently expanded the resistance value ranges of the 0201 chip size of the RNCF Series of precision thin film chip resistors. Resistance values from 49.9 ohm to 33K ohm are now available in tolerances as tight as 0.5% and TCR as low as 25 ppm. With the proliferation of consumer electronics and the desire […]
