Vishay launches high-power, thin-film chip resistors for automotive industry

By Michelle Froese

Vishay Intertechnology has introduced a new series of AEC-Q200-qualified, high-power, thin-film wraparound chip resistors.

The Vishay Dale Thin Film PHPA series devices combine power ratings of 1.0 and 2.5 W in the 1206 and 2512 case sizes, respectively, with a self-passivated, tantalum-nitride film for high moisture resistance.

The devices are available for automotive power supplies, braking systems, on-board chargers, motor-deflection circuits, and industrial test and measurement equipment.

For precision performance in these applications, the resistors combine their high power ratings with low absolute TCR — down to ± 25 ppm/° C and tolerances down to ± 0.1 %.

PHPA series devices offer a resistance range from 10 Ω to 30.1 kΩ, low noise of less than -30 dB, low-voltage coefficients of < 0.1 ppm/V, and a working voltage of 200 V.

Featuring a high-purity ceramic substrate, the resistors are designed with enlarged backside terminations to reduce the thermal resistance between the topside resistor layer and the solder joint on the PCB.

The devices are RoHS-compliant, halogen-free, and flame-resistant in accordance with UL 94 V-0. They operate over a wide temperature range of -55° to +155° C. Samples of the PHPA series are available now.
