The specification process for resistors involves more than just allowing for tolerance bands. Voltage, power, and temperature ratings can interact in ways that can degrade circuit reliability. Kory Schroeder, Stackpole Electronics, Inc. Although not a complex component, resistors have specifications that can be confusing, misleading, and misinterpreted. When specifying performance qualities, it is important to […]

Radial leaded MOV’s for general purpose overvoltage protection
Stackpole’s RV Series of radial leaded metal oxide varistors is available in a wide range of disk sizes and working voltages designed for general purpose overvoltage protection. The RV Series is UL1449 certified and offers disk sizes from 5mm up to 20mm with peak current ratings up to 18,000 amps and energy handling up to […]
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 […]
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 […]
0603 X 4 chip arrays Now AEC-Q200 qualified
Stackpole has completed AEC-Q200 testing for the RACF and RAVF Series thick film chip resistor arrays in its most popular size, the 0603 by 4 resistors. Per AEC-Q200, these chip resistor arrays must have an operating temperature range of -55 degree C to +150 degree C and survive a wide range of electrical and mechanical […]
Stackpole’s ASRM2 2-Watt Resistors
Stackpole’s addition of ASRM2 is a mini 2 W power rating in its ASR series of axial leaded anti-surge resistors. It is the same size as the ASR1, has the same working voltage rating of 4 KV and overload voltage rating of 5 KV, yet rated for 2 W of continuous power. The ASR series […]
High Power to Size Ratio from Super Mini Metal Film Resistors
Stackpole’s flameproof RNS Series is ideal for existing designs that require downsizing or added features. It is also a popular choice for new designs that require the smallest form factor possible for a given power rating. Specifically, the RNS Series 1W has an EIA standard ¼ watt body size, and the RNS 2W has an […]
