High energy double-sided chip resistors handle up to 6.5 kV surges
TT Electronics announced high energy double-sided chip (HDSC) resistors, the latest addition to its range of pulse withstanding chip resistors. HDSC chip resistors are untrimmed for improved pulse performance – the only double-sided untrimmed chip resistors on the market – and are ideal for industrial and medical applications such as power supplies, circuit breakers, and […]
Busbar-mounted shunt resistor measures currents in the hundreds-of-amps range
TT Electronics announced E-Beam Welded Shunt resistors for industrial and automotive applications. EBW8518 is an electron beam welded resistance element, sandwiched between large copper terminals with optional tin plating. Precision applications can make use of its 1% tolerance, 100ppm/°C TCR, 1µV/°C thermal EMF and separate ground pins to reduce errors. The low measurement error of […]
Foil-on-ceramic current-sense resistors offer values down To 2.5 mΩ
The CSRF Series utilizes foil-on-ceramic technology to achieve low values in small chip sizes. The 0.25-W rated CSRF0402 – HP, for example, is available in resistance values from 20 mΩ down to 2.5 mΩ. TCR ranges from ±400 ppm to ±200 ppm are possible depending on resistance value with tolerances as low as 1%. This […]
Ultra-precision current-sense chips feature resistance range to 80 mΩ
The CSSH2512 from Stackpole is an all metal current sense chip resistor capable of precision tolerances as low as 0.5% and TCR as low as 15 ppm. The resistance range for the 3-W 2512 size chip has been expanded and now spans from 0.5 mΩ up to 80 mΩ. The high precision combined with the […]
Keys to understanding resistor specs
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 […]
Current-sense resistors designed for use in high-sulfur environments come in 0402 packages
KOA Speer Electronics has expanded its SR73-RT Series of Low Resistance Anti-Sulfuration Current Sense Resistors with a new 0402 Package size. The SR731E-RT will be available in ±1%, ±2%, and ±5% tolerances with resistance values from 1Ω up to 10 Ω, a power rating of 1/8 Watt and an operating temperature of -55°C to +155°C. […]
UL94V-0-compliant wirewounds offer wide range of power ratings and tolerances
The WW Series high temperature silicone coated wirewound resistors meet UL94V-0 flammability requirements. The all-welded WW is available in power ratings from 0.5 W up to 11 W and tolerances from 5% to 0.1%. Typical TCR for the WW series ranges from 90 ppm or better for resistance values below 1 Ω to 20 ppm […]
