PEWM2512 by RESI – High-Performance 0-Ohm Jumper in a Compact SMD Package

High current-carrying capability, compact dimensions and a robust metal alloy: With the PEWM2512 series, RESI offers an interesting solution for applications where PCB traces need to be bridged or high currents need to be reliably carried across the printed circuit board.

With the PEWM2512 series, RESI expands its portfolio with a high-performance 0-ohm SMD resistor / jumper in the established 2512 package size. Unlike conventional thick-film 0-ohm resistors, the component is based on a copper alloy (metal alloy) and is specified for a rated power of up to 3 W.

This makes the series particularly suitable for applications where compact dimensions need to be combined with a robust electrical connection.

Metal Alloy Instead of a Conventional Resistive Layer

A key feature of the PEWM2512 is its copper alloy construction. The specified resistance value is 0 Ω, meaning that the component is primarily used as a high-performance electrical bridge.

In PCB designs, such jumpers can be used, for example, to provide flexible current paths, implement trace crossings or enable different assembly variants using a common PCB layout.

Thanks to its standardized 2512 SMD package, the PEWM2512 can be easily integrated into automated SMT production processes.

Designed for Demanding Temperature Conditions

The PEWM2512 is designed for an operating temperature range of –55 °C to +170 °C. This provides sufficient thermal margin for applications with elevated ambient temperatures or significant self-heating.

AEC-Q200 Qualified

Another important feature is the series' AEC-Q200 qualification. This makes the PEWM2512 suitable for applications with increased requirements regarding reliability and environmental conditions.

RESI lists power tools and consumer electronics among the typical application areas. Beyond these examples, the concept is generally of interest wherever a robust 0-ohm current path is required within a compact SMD package.

More Than Just “0 Ohms”

At first glance, a 0-ohm resistor may appear to be a rather simple component. In power-oriented circuits, however, factors such as current-carrying capability, thermal behavior, connection reliability and long-term stability can be crucial.

The PEWM2512 combines a robust metal alloy construction with the widely used 2512 package size and a specified power rating of 3 W. This makes it an interesting alternative to conventional 0-ohm chip resistors or more complex PCB design solutions.
