Chip Resistors Deliver TCRs To ±25 ppm/°C

The PHP series high-power thin film chip resistors feature an absolute TCR of ±25 ppm/°C, tolerances down to ± 0.1 %, and power ratings from 1W to 2.5W over a temperature range of -55°C to +125°C. Featuring a high-purity ceramic substrate, the resistors employ enlarged backside terminations to reduce thermal resistance between the topside resistor layer and the solder joint on the PCB. Offered in 1206 and 2512 case sizes, resistance values range from 10Ω to 30 kΩ with non-standard values available. Typical pricing for the 1206 case size with a 0.1 % tolerance and TCR of ± 25 ppm/°C is $0.48 each/1,000. VISHAY INTERTECHNOLOGY, INC., Malvern, PA. (619) 336-0860.
