Potentiometer EB72707123 1 kΩ 100 mW – adjustable resistor component

Potentiometer EB72707123 1 kΩ 100 mW is an adjustable resistor designed to provide manual control over circuit resistance for tuning, calibration and signal-level adjustments. With a nominal resistance of 1 kΩ and a power handling of 100 mW, this component is suitable for low-power electronic applications such as prototypes, repair work and component replacement. The compact form factor and straightforward mounting make it practical for use on breadboards, perfboards and small PCBs where space is limited.

Advantages

The potentiometer delivers precise variable resistance across its range, enabling accurate adjustment of voltage dividers and signal attenuation. Its low power rating matches common small-signal and control circuits, and the compact size simplifies integration into tight layouts. Mechanical adjustment provides immediate feedback and repeatable settings without the need for software or external power. The device is a cost-effective option for manual tuning during development and maintenance tasks.

Suitable for

• Prototyping and breadboard experiments
• Repair and replacement in consumer electronics and instrumentation
• Volume, tone or level controls in low-power audio circuits
• Calibration and trimming of sensor inputs and reference voltages

Key specifications

• Nominal resistance: 1 kΩ
• Power rating: 100 mW
• Type: adjustable potentiometer (manual)
• Mounting: suitable for direct PCB or panel mounting depending on variant
• Adjustment method: mechanical rotary or slide control depending on package
• Typical application range: low-power signal and control circuits

How to use

Install the potentiometer according to the circuit schematic as a variable resistor or as part of a voltage divider. Ensure correct orientation of the three terminals for use as a variable voltage output or two terminals for rheostat operation. Observe the 100 mW power rating and keep dissipation within safe limits by calculating expected current and voltage across the component. Use a suitable knob or tool for adjustment and secure the component mechanically to prevent movement during operation.

Usage recommendations

For reliable operation, avoid subjecting the potentiometer to currents or voltages that exceed its power rating. When used in permanent assemblies, consider securing connections with solder and strain relief to prevent intermittent contact. During testing and calibration, adjust slowly and monitor circuit response to prevent overshoot or unintended stress on downstream components.
