Potentiometer 10 kΩ 100 mW EB1921308503 — rotary adjustable resistor

Single-turn potentiometer 10 kΩ 100 mW EB1921308503 is a compact rotary adjustable resistor intended for low-power signal and voltage control in electronic circuits. The component is designed for board mounting and manual tuning, providing precise variable resistance within a 10 kiloohm range. Its single-turn design allows simple and quick adjustments for calibration, level setting, or user controls in small devices and prototypes.

Advantages

This potentiometer offers a stable linear resistance curve suitable for accurate adjustments and repeatable settings. Its low power rating of 100 mW makes it appropriate for signal-level applications where heat dissipation and power consumption are limited. The rotary single-turn construction enables straightforward mechanical operation and compact footprint on printed circuit boards. The design provides reliable contact and smooth rotation for long-term manual tuning.

Suitable for

• Audio devices for level and tone adjustment
• Instrumentation and measurement circuits requiring fine tuning
• Control panels and user interfaces with low-power signals
• Prototype boards and development modules for circuit calibration

Key specifications

• Resistance value: 10 kΩ (10,000 ohms)
• Power rating: 100 mW
• Type: single-turn rotary potentiometer
• Mounting: board-mount (PCB)
• Adjustment: manual rotary shaft
• Taper: linear (suitable for proportional control)
• Typical use: low-power signal and voltage adjustment

How to use

Install the potentiometer on the PCB according to the board layout, ensuring correct orientation of the three terminals for the required wiring (end-to-end and wiper). Apply a supply or signal within the device limits and rotate the shaft to vary resistance and adjust output level. For calibration, make small incremental turns while monitoring the circuit outcome until the desired level is reached. Avoid exceeding the specified power rating and ensure that the applied voltage and current remain within safe limits for low-power operation.

Usage recommendations

Use this 10 kΩ, 100 mW potentiometer for signal-level adjustments rather than power regulation. Maintain moderate rotational force during adjustment, protect the component from mechanical shock, and avoid prolonged exposure to high ambient temperatures to preserve performance and contact reliability.
