VSH shares traded at $31.25, down $0.70, or 2.21%, in midday action. The move came as Vishay Intertechnology introduced its new RPWA 650 series of thick film power resistors. These devices deliver 650 W of continuous power inside a low profile package, and Vishay Intertechnology positions the release as a step toward higher power density for demanding applications.
Vishay Intertechnology, Inc., VSH
Vishay Intertechnology designed the series to cut component counts while saving valuable board space. The company also built in customizable cabling and optional temperature sensing, so engineers gain flexibility during integration. As a result, Vishay Intertechnology aims to simplify both design work and final assembly for its customers.
New RPWA 650 Series Resistors Deliver High Power in Compact Form
The RPWA 650 series stands out through its high power capability paired with a compact footprint. Vishay Intertechnology achieved this through a cold system baseplate design that transfers heat efficiently to an external heatsink. Consequently, the resistors maintain stable performance across a wide temperature range, from -55°C to +155°C.
Engineers can rely on the RPWA 650 series to reduce the number of parallel resistors needed in a layout. Vishay Intertechnology embedded an optional NTC temperature sensor directly into the housing alongside the power resistor. This combination trims wiring complexity and shortens the path to plug and play integration.
Because the design uses customizable cabling and self-calibrating pressure mounting, board-level soldering becomes unnecessary. Vishay Intertechnology built this feature specifically to accelerate assembly timelines for power modules. Design teams therefore gain a faster, simpler route from prototype to finished product.
Design Flexibility and Applications Across Harsh Environments
Vishay Intertechnology offers the RPWA 650 series across a resistance range from 6.2 Ω to 1 MΩ. Tolerances go down to ±5%, giving engineers precision where circuits demand it. This range supports functions including precharge, discharge, active discharge, power conversion, and snubber operations.
The resistors handle high voltage duty with a maximum operating voltage of 6000 VDC. Vishay Intertechnology also rated the devices for dielectric strength up to 7000 VRMS. Typical self-inductance stays at or below 40 nH, which limits transient overshoot in fast-switching circuits.
Pulse energy performance rounds out the technical profile, supporting up to 3.5 J per pulse. Vishay Intertechnology built the RPWA 650 series for automotive, energy, industrial, medical, and avionics systems. The resistors are RoHS-compliant and currently pending AEC-Q200 qualification for automotive-grade use.
