Precision Thin Film Chip Resistors come in 0603/0805 case sizes.
Press Release Summary:
Along with respective power ratings of 0.375 and 0.675 W, 0603 and 0805 case size resistors of PHP series offer absolute TCR of ±25 ppm/°C and tolerances down to ±0.1% over -55 to +125°C range. Products exhibit stable film and performance characteristics of 1,000 ppm at +70 °C for 2,000 hr. In addition to high-purity ceramic substrate, devices have enlarged backside terminations that reduce thermal resistance between topside resistor layer and solder joint on circuit board.

Vishay Extends PHP Precision, High-Power Thin Film Chip Resistors to 0603 and 0805 Cases
Devices Offer High Power Ratings of 0.375 W in the 0603 Case Size and 0.675 W in the 0805
MALVERN, Pa. — Vishay Intertechnology, Inc. (NYSE: VSH) today announced that it has extended its PHP series of precision high-power thin film chip resistors with new devices in the compact 0603 and 0805 case sizes offering high power ratings of 0.375 W and 0.675 W, respectively. The Vishay Dale Thin Film devices combine their high power with a low absolute TCR of ± 25 ppm/°C and tolerances down to ± 0.1 % over a wide temperature range of -55 °C to +125 °C.
With stable film and performance characteristics of 1000 ppm at +70 °C for 2,000 hours, the resistors released today are optimized for high-precision medical imaging and for industrial, telecommunications, and test and measurement instrumentation and equipment. Featuring a high-purity ceramic substrate, the devices are designed with enlarged backside terminations to reduce the thermal resistance between the topside resistor layer and the solder joint on the end users’ circuit board.
Offered in the 0603, 0805, 1206, and 2512 case sizes, the PHP series offers a resistance range from 10 Ω to 30.1 kΩ, with non-standard values available. With power ratings up to 2.5 W, the resistors feature 2x the power rating over traditional thin film chip resistors in the same case sizes, low noise of < -30 dB, low voltage coefficients of 0.1 ppm/V, and voltage ratings from 75 V to 200 V. Available with lead (Pb)-free or lead terminations, the devices are RoHS-compliant and flame-resistant in accordance to UL 94 V-0.
Samples and production quantities of PHP series devices in the 0603 and 0805 case sizes are available now, with lead times of eight to 10 weeks for standard orders. Pricing for U.S. delivery varies by tolerance and case size. For example, typical pricing for the 0603 case size with a ± 0.1 % tolerance and TCR of ± 25 ppm/°C is $0.50 per piece in 1,000-piece quantities.
