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 […]
Fusible wirewounds offer advanced pulse handling, failsafe operation
The WWF Series from Stackpole is a fusible wirewound technology. Wirewounds typically handle at least 5 times the pulse energy of similar film resistors. Although this attribute is ideal for surge handling, it creates a risk under continuous overloads where the part may continue to generate heat until igniting itself, the PCB, or surrounding components […]
612-size current sense resistors now offered in 2mΩ resistance value
Stackpole has expanded the value range of its CSRF0612 surface mount resistors. The 0612 size features terminations on the long side of the part for improved power handling, heat dissipation, and lower resistance values. The CSRF0612 handles 1.5 watts versus the equivalently sized 1206 chip that is only rated at 1 watt. This lower resistance […]
New catalog covers passive power components
Würth Elektronik eiSos, a leading European manufacturer of electronic and electromechanical components, has published its “Passive Components 2017” product catalog. Numerous products are presented on 776 pages in the categories EMC Components, Power Magnetics, Signal & Communications, and AEC-Q qualified products. The “Passive Components 2017” catalog can now be requested online at www.we-online.com/newcatalog. The same […]
Thick film chip resistor offers tolerance of ±0.25%
KOA Speer Electronics introduces the new high precision (±0.25%) thick film chip resistor RK73G. Compared to KOA’s general purpose RK73 series, the new RK73G has an even better T.C.R. of ±50 ppm/°C and its new tolerance of ±0.25% is ideal for precision designs such as high accuracy sensing or voltage detection circuits in automotive and […]
0201 size chip resistor offers a 0.063W power rating
The RMCP Series from Stackpole is a thick film chip resistor series with high power ratings for a given chip size. Stackpole recently added an 0201 size chip resistor with a power rating of 0.063W while the usual power rating for this size is 0.050W. This high power capability allows the RMCP0201 to be used […]
MELF resistor technology provides cooler operating temperatures at full-rated power
Stackpole’s MLF / MLFM is a series of metal film, surface mount MELF resistors. The MELF technology provides cooler operating temperatures than flat chip resistors at full rated power. For example, the MLFM1 will typically run more than 70 degrees C cooler than the equivalent 1W 2512 size flat chip resistor and has a smaller […]
