RT1206WRC072K4L 2.4KΩ 1% 1206 Thick Film Chip Resistor

ElecSuppliers Part Number GuideAug 22, 2026

RT1206WRC072K4L is a 2.4 KΩ thick film chip resistor designed for general electronic and power-related circuits. It provides a nominal resistance of 2.4 KΩ with a ±1% tolerance and uses a 1206 surface-mount package.

Compared with smaller 0402 and 0603 resistors, the 1206 package provides a larger physical footprint and greater power-handling capability. This makes the component suitable for applications where PCB space is available but a more robust resistor package is preferred.

RT1206WRC072K4L Key Specifications

RT1206WRC072K4L has a resistance value of 2.4 KΩ and a tolerance of ±1%.

The resistor uses thick film technology and a two-terminal surface-mount construction. The 1206 package corresponds to approximately 3.2 mm × 1.6 mm.

The component is designed for general-purpose electronic applications and can be used in voltage-divider, biasing, feedback and signal-conditioning circuits.

2.4KΩ 1206 Chip Resistor

A 2.4 KΩ resistor can be used in many analog and digital circuits.

One common application is a voltage divider. When combined with another resistor, RT1206WRC072K4L can establish a specific voltage for an ADC input, feedback pin, monitoring circuit or control signal.

The 2.4 KΩ value can also be used for transistor biasing and signal pull-up or pull-down functions.

Because the component has a ±1% tolerance, it is suitable for circuits where resistance accuracy is more important than with standard 5% resistors.

1206 Thick Film Resistor

The 1206 package is larger than many miniature chip-resistor formats.

Its larger body provides more physical area for heat dissipation and makes the component easier to handle during PCB assembly and repair.

The package is commonly used in industrial electronics, power supplies, control equipment and other applications where a 0402 or 0603 resistor may be unnecessarily small.

For high-density consumer electronics, designers may prefer smaller packages. For applications where power handling and mechanical robustness are more important, 1206 can be a practical choice.

RT1206WRC072K4L Power Handling

The power capability of a resistor depends on its package, construction, ambient temperature and mounting conditions.

The larger 1206 package provides more thermal area than miniature chip resistors, allowing it to handle greater power under suitable conditions.

Actual power dissipation can be calculated using:

P = I²R

or:

P = V²/R

For a 2.4 KΩ resistor, increasing the voltage across the component increases power dissipation rapidly.

Engineers should therefore calculate the maximum expected operating voltage and current rather than selecting the resistor solely according to its nominal resistance.

±1% Resistance Tolerance

RT1206WRC072K4L has a ±1% resistance tolerance.

For a nominal value of 2.4 KΩ, this corresponds to an initial resistance range of approximately 2.376 KΩ to 2.424 KΩ.

This tolerance is useful in voltage-divider and feedback circuits where resistor variation can influence the final circuit voltage.

When multiple resistors are used together to determine a regulated voltage, the tolerance of every resistor in the network should be considered.

Thick Film Construction

RT1206WRC072K4L uses thick film resistor technology.

Thick film resistors are widely used because they provide a practical combination of cost, size, resistance range and general electrical stability.

They are suitable for a large number of electronic applications and can be manufactured in many resistance values and package sizes.

For ordinary digital and analog circuits, thick film technology provides a straightforward solution without the need for more specialized resistor construction.

RT1206WRC072K4L Applications

RT1206WRC072K4L can be used in a broad range of electronic equipment.

Typical applications include:

Voltage divider circuits

Feedback networks

Transistor bias circuits

Signal conditioning

Pull-up and pull-down networks

Control circuits

Power-management circuits

Industrial electronics

The 2.4 KΩ resistance value is suitable for both analog and digital circuit functions where a moderate resistance is required.

RT1206WRC072K4L Voltage Divider

Voltage-divider circuits are one of the most common uses for a 2.4 KΩ chip resistor.

When two resistors are connected in series, the voltage at the midpoint is determined by the resistance ratio.

RT1206WRC072K4L can therefore be combined with another resistor to create a required sensing or feedback voltage.

For example, the resistor can be used in a power-supply feedback network to scale a higher voltage down to a level suitable for a controller or monitoring input.

The ±1% tolerance helps keep the divider ratio relatively consistent between individual assemblies.

RT1206WRC072K4L PCB Design

The 1206 package is relatively easy to place compared with miniature 0402 and 0603 components.

Its larger dimensions provide more room for solder pads and can make manual inspection and repair easier.

However, the PCB footprint should still follow appropriate manufacturing recommendations.

When the resistor is used for higher-power applications, sufficient copper area around the component can help transfer heat into the PCB.

The distance from heat-sensitive components should also be considered.

RT1206WRC072K4L Replacement

When replacing RT1206WRC072K4L, the first parameter to match is the 2.4 KΩ resistance value.

The ±1% tolerance should also be maintained when the original circuit depends on the specified resistance accuracy.

The 1206 package is another important consideration. A replacement with the same resistance but a substantially smaller package may have insufficient power capability.

For precision applications, temperature coefficient and operating-temperature characteristics should also be compared.

RT1206WRC072K4L Compared With Smaller Resistors

The main advantage of a 1206 resistor over smaller packages is its physical size and associated thermal capability.

A 0402 resistor may be preferable when PCB space is extremely limited, while a 1206 resistor can be a better choice when power dissipation, mechanical handling or inspection is more important.

The choice should therefore be based on the actual circuit requirements rather than package size alone.

For a 2.4 KΩ resistor operating at relatively low power, either package size may work electrically, but the larger 1206 package can provide additional thermal margin.

RT1206WRC072K4L for PCB Applications

RT1206WRC072K4L provides a 2.4 KΩ resistance with ±1% tolerance in a widely used 1206 surface-mount package.

Its combination of thick film construction, compact size and practical power-handling capability makes it suitable for voltage dividers, feedback circuits, signal networks and general electronic equipment.

For new designs, engineers should evaluate resistance, tolerance, power dissipation, voltage and temperature conditions together. For replacement applications, matching the complete electrical specifications and 1206 package helps maintain the original circuit performance.
