Tantalum nitride-based precision thin-film resistors are impervious to corrosion caused by moisture because they are self-passivating. The RTAN series from Stackpole is a tantalum nitride thin film chip resistor that withstands biased humidity testing at 85oC, 85% relative humidity, ten per cent rated power with very little resistance shift
Stackpole’s CSRF2817 foil on ceramic current sensing chip resistor offers a power rating of up to five watts and resistance values of five, six, eight, ten, 15, 20 and 33 milliohm. TCR for these values is 50 ppm and available tolerances are one and five percent.
Vishay Intertechnology, Inc. (NYSE: VSH) today announced that the company has extended its TNPU e3 series of Automotive Grade ultra precision thin film flat chip resistors with lower temperature coefficients down to ± 2 ppm/K in the 0603, 0805, and 1206 case sizes.
This new chip resistor is made using a thick film element printed onto a ceramic substrate and complements the other circuit conditioning components that Bourns offers such as power inductors and rectifier diodes.
Vishay Extends Resistance Range Of 1206 AT Precision Series Thin Film Chip Resistors. The resistor features an operating voltage of 200 V, the power rating of 400 mW at +70 °C ambient temperature, and operates over a -55 °C to +155 °C temperature range. The device is AEC-Q200 qualified and RoHS-compliant.
Industrial and commercial power electronics demand robust power supply performance. When high stability and low thermal resistance are important, standard chip resistors may not be the best solution. RMCW thick film wide termination chip resistors with reverse geometry provide terminations on the long sides of the chip, as opposed to the short side terminal for standard chips.
