RC0402JR-070RL 0 Ohm 0402 Jumper Resistor

ElecSuppliers Part Number GuideSep 06, 2026

RC0402JR-070RL is a YAGEO RC series thick film chip resistor with a nominal resistance of 0 ohms. Rather than being used to provide a conventional resistance value, this component functions primarily as a compact PCB jumper.

The 0402 package allows designers to replace traditional wire links with a surface-mount component that can be placed automatically during PCB assembly. This makes RC0402JR-070RL useful for compact electronic products and high-density circuit boards.

A Zero-Ohm Component for PCB Configuration

A 0 ohm resistor provides a convenient way to electrically connect two PCB nodes while retaining the appearance and assembly process of a conventional chip resistor.

RC0402JR-070RL can be used to configure different circuit paths during PCB development. Designers can populate or omit the component according to a particular product configuration, allowing one PCB layout to support multiple hardware versions.

This approach can reduce the need for separate PCB layouts when only minor routing or configuration changes are required.

Compact 0402 Package

RC0402JR-070RL uses the 0402 imperial package, corresponding to approximately 1.00mm × 0.50mm in metric dimensions. Its compact size is well suited to modern high-density circuit boards.

The small footprint also allows the component to be placed using standard SMT production equipment. Compared with manually installed wire jumpers, a 0402 chip jumper provides a more consistent solution for automated manufacturing.

Its maximum seated height is approximately 0.40mm, which is useful in products where component height is restricted.

Thick Film Construction

The device uses thick film resistor construction and has two terminals. Although the nominal resistance is 0 ohms, it should not be treated as a perfectly lossless electrical connection.

The actual circuit must still account for the component's electrical limitations, including its rated power and maximum voltage. For applications involving significant current, designers should verify the complete specification and operating conditions rather than assuming that every 0 ohm resistor can carry unlimited current.

Temperature Range and Reliability

RC0402JR-070RL is specified for an operating temperature range of -55°C to +155°C. This broad temperature range allows it to be used in a variety of commercial and industrial electronic environments.

The component is also designed as a moisture-resistant chip resistor, providing additional flexibility for PCB applications where environmental conditions need to be considered.

Its 0402 construction combines a small footprint with the manufacturing advantages of a standardized surface-mount component.

Typical Uses of RC0402JR-070RL

One common use is PCB routing. A designer can place a 0 ohm resistor between two points where a direct copper connection may not be convenient because of layout constraints.

It can also be used for circuit option selection, signal-path configuration, component substitution and engineering prototypes. A PCB can contain several jumper positions, allowing different versions of a product to be configured simply by changing which 0 ohm components are installed.

In production, the same component can be assembled using automated pick-and-place equipment alongside ordinary resistors, capacitors and other SMT devices.

RC0402JR-070RL in High-Density PCB Design

As electronic products become smaller, traditional wire jumpers become less practical. A 0402 zero-ohm jumper can provide the same basic electrical connection while occupying very little board space.

For multilayer PCBs, the component can also provide a convenient connection between nearby circuit nodes where routing directly with copper would complicate the board layout.

When selecting RC0402JR-070RL, designers should evaluate the expected current, power dissipation, voltage and temperature conditions. Correct PCB pad design and soldering conditions are also important for reliable SMT assembly.

RC0402JR-070RL provides a simple and space-efficient way to implement electrical jumpers and configurable PCB connections while maintaining compatibility with automated surface-mount manufacturing.
