New Vishay Dale Thin Film Wraparound Chip Resistor is released by New Yorker Electronics
Vishay Precision Performance Resistor Series Significantly Reduces Board Space and Component Counts by Replacing Larger Resistors
The AEC-Q200 qualified, high-power thin film resistor series combines power ratings of 1.0W and 2.5W in the 1206 and 2512 case sizes, respectively. They significantly reduce board space and component counts by replacing larger or paralleled resistors. Vishay PHPA resistors are designed with enlarged backside terminations to reduce the thermal resistance between the topside resistor layer and the solder joint on the end user's circuit board.
Most thin film chip resistors have a low power capability so to accommodate higher power applications, several chips must be used. In hazardous or unstable environmental conditions, resistors need to be fabricated with resistive materials that can handle the elements. The Vishay thin film series is fabricated with tantalum nitride (Ta2N), which offers superior moisture resistance and high thermal stability in harsh conditions. In addition, the devices' power capability far exceeds the industry standard.
The 1206 case size offers a resistance range of 12 to 30.1 Ω while the 2512 supplies a range of 10 to 30.1 Ω. The resistors have an ESD rating 5A (HBM) a resistor tolerance to ± 0.1% and TCR to ±25 ppm/°C. These qualities present new product design advantages such as reduced component count, increased design flexibility with higher power capability, reduced assembly costs and improved board-level reliability.
The resistor's actual power-handling capability is limited by the end user mounting process. As with any high power chip resistor the ability to remove the generated heat is critical to the overall performance of the device.
