RWR74S5620FRBSL Vishay Dale 562Ω 5W Wirewound Resistor

ElecSuppliers Part Number GuideAug 22, 2026

RWR74S5620FRBSL is a Vishay Dale wirewound resistor designed for applications requiring higher power handling, stable resistance and reliable operation under demanding environmental conditions. It has a resistance of 562 Ω, a tolerance of ±1% and a rated power of 5 W.

The component belongs to the RWR74S series, a military resistor family associated with MIL-PRF-39007 requirements. Its wirewound construction and rugged axial package make it different from the small surface-mount resistors commonly used in general electronic circuits.

RWR74S5620FRBSL Key Specifications

RWR74S5620FRBSL provides a nominal resistance of 562 Ω with a ±1% tolerance. Its rated power is 5 W and its temperature coefficient is ±20 ppm/°C.

The resistor has an axial through-hole construction with an approximate body diameter of 7.92 mm and length of 22.23 mm. It operates across a temperature range of -55°C to +250°C.

The combination of relatively high power capability and low temperature coefficient makes the component suitable for circuits where both heat dissipation and resistance stability are important.

562Ω 5W Wirewound Resistor

A 562 Ω resistor can be used in a variety of power and control circuits, including current limiting, voltage dropping, load applications, bias networks and power dissipation circuits.

The 5 W rating allows RWR74S5620FRBSL to handle substantially more power than standard low-power chip resistors. This makes it useful in circuit locations where a resistor is expected to dissipate significant energy during normal operation.

The actual operating power should nevertheless be kept within the manufacturer's recommended limits. Thermal conditions, ambient temperature and PCB mounting can all affect the temperature reached by the resistor.

RWR74S Series Military Resistor

RWR74S5620FRBSL is part of Vishay Dale's RWR74S military resistor series. The series is designed for demanding applications and includes moisture-resistant characteristics.

The military-oriented construction makes the series suitable for applications where reliability and environmental resistance are more important than simply minimizing component size.

The RWR74S family includes many resistance values and electrical configurations. The complete part number should therefore be checked carefully when selecting or replacing a component.

RWR74S5620FRBSL Temperature Performance

One of the notable characteristics of RWR74S5620FRBSL is its ±20 ppm/°C temperature coefficient.

A resistor's resistance changes as its temperature changes. A lower temperature coefficient generally means that the resistance remains closer to its nominal value across changes in operating temperature.

This can be useful in power circuits, instrumentation and control systems where resistance changes caused by temperature could affect the circuit's operating point.

The specified operating temperature range of -55°C to +250°C also gives designers considerable flexibility when the resistor is used in harsh-temperature environments.

RWR74S5620FRBSL Power Handling

The 5 W power rating is an important reason to select this component instead of a smaller general-purpose resistor.

When electrical power is dissipated in a resistor, the component converts that energy into heat. As the dissipated power increases, the resistor temperature also rises.

For continuous operation, designers should provide adequate thermal conditions and maintain suitable safety margins. Nearby components should also be positioned far enough away to avoid unwanted heat transfer.

The resistor's axial construction provides a larger physical body than typical SMD resistors, which is appropriate for a component intended to handle higher power.

RWR74S5620FRBSL Applications

RWR74S5620FRBSL can be used in military electronics, industrial equipment, power supplies, control systems, instrumentation and other high-reliability electronic assemblies.

Typical circuit functions include current limiting, load resistance, voltage dropping and power dissipation.

The 562 Ω resistance value can also be useful in circuits that require a specific resistance rather than a commonly rounded value such as 560 Ω. With ±1% tolerance, the component provides tighter resistance accuracy for designs where the nominal value needs to be maintained more closely.

Axial Through-Hole Package

Unlike many modern power resistors that use surface-mount packages, RWR74S5620FRBSL uses an axial through-hole configuration.

The approximate 22.23 mm body length and 7.92 mm diameter should be considered when designing the PCB. The larger body also means that sufficient clearance should be provided around the resistor, especially when it is operated at a significant fraction of its rated power.

Through-hole construction can be advantageous in equipment where mechanical robustness and serviceability are important. It also makes the component suitable for PCB assemblies that continue to use axial power resistors.

RWR74S5620FRBSL Replacement Considerations

When replacing RWR74S5620FRBSL, resistance alone is not enough to determine compatibility.

The replacement should match the 562 Ω resistance, ±1% tolerance, 5 W power rating and required temperature coefficient. The package dimensions and axial lead configuration should also be checked.

For high-reliability or military applications, the qualification and environmental characteristics are particularly important. A standard commercial 562 Ω resistor may have similar resistance and power specifications but may not provide equivalent environmental performance.

The complete RWR74S5620FRBSL part number should therefore be used when searching for an exact replacement.

RWR74S5620FRBSL Availability

RWR74S5620FRBSL is still listed by multiple electronic component distributors as an active Vishay Dale product. Current listings identify the component as a 562 Ω, 5 W, ±1% wirewound axial resistor.

Actual stock levels vary between suppliers and regions, so buyers should verify current inventory and lead time before placing production orders.

For long-term procurement, it is also useful to confirm the exact manufacturer, part number, packaging and required qualification rather than relying solely on a distributor's product description.

RWR74S5620FRBSL for High-Reliability Electronics

RWR74S5620FRBSL combines a 562 Ω resistance value, ±1% tolerance, 5 W power rating and ±20 ppm/°C temperature coefficient in a rugged axial wirewound package.

Its RWR74S series construction makes it particularly relevant to applications where power handling, temperature performance and environmental reliability are important.

For new designs, engineers should evaluate power dissipation, temperature rise, PCB spacing and operating environment together. For replacement applications, matching the complete electrical and mechanical characteristics is the safer approach than selecting another resistor based only on the 562 Ω value.
