Product Introduction
The RC122N-H is a 12mm thin horizontal rotary potentiometer designed for radio tuning and compact electronic control applications. Its low-profile circular body and PCB terminals support installation in products with limited internal space. The rotary structure allows users to adjust resistance through manual shaft movement.
The supplied series specifications cover resistance values from 1KΩ to 1MΩ, low rotational noise, and a rotational life of at least 10,000 cycles. The exact electrical and mechanical configuration should be confirmed for the selected model.
The RC122N-H is suitable for OEM and ODM projects. The MOQ starts at 5,000 pieces, with a reference price of US$0.12 per piece. Better prices are available for larger orders.
Key Features
1. Thin Rotary Structure
The RC122N-H features a thin, circular body designed for compact electronic assemblies. Its low-profile construction can help reduce the space required behind a control panel. This makes it a practical option for products where installation depth and PCB layout are important design considerations.
2. Horizontal PCB Mounting
The horizontal mounting structure allows the component to be installed on a printed circuit board while keeping the rotary control accessible. PCB terminals support electrical connection to the host circuit. Engineers should check the terminal layout and mounting dimensions against their board design before production.
3. Compact Radio Tuning Control
The RC122N-H is intended for radio tuning and related electronic control applications. Its rotary interface supports manual adjustment within the connected circuit. The compact construction is useful when designing radios and other electronic devices that require a rotary control without taking up excessive internal space.
4. Multiple Resistance Options
The supplied series specification covers total resistance values from 1KΩ to 1MΩ. This range provides options for different circuit designs. Resistance taper and tolerance should be selected according to the intended application. Confirm the required resistance and electrical characteristics before placing a production order.
5. Low Rotational Noise
The supplied series data specifies rotational noise of no more than 100mV. This parameter is relevant when evaluating the electrical behavior of a variable resistor during adjustment. Actual suitability depends on the circuit design, selected resistance characteristics, and the performance requirements of the finished equipment.
6. Defined Mechanical and Electrical Performance
The series specification lists a rotational torque of 10–70 gf·cm and a rotational life of at least 10,000 cycles. It also provides limits for residual resistance, insulation resistance, and withstand voltage. These values offer a reference for engineering evaluation, subject to confirmation for the exact model.

Note: The provided series drawing lists different rotational angles for the RC101 and RC141/RC161 series. The exact rotational angle, resistance tolerance, terminal configuration, and mechanical dimensions of the RC122N-H should be confirmed against its model-specific drawing before final specification approval.
Customization Options
For OEM and ODM projects, the required electrical and mechanical configuration should be confirmed before production. Customers can provide the target resistance value, resistance taper, operating voltage, control requirements, and PCB mounting details for evaluation.
The series documentation includes different thin rotary configurations, body diameters, thicknesses, heights, and shaft or control-interface styles. The applicable options depend on the exact model and should not be assumed to be interchangeable.
For a replacement project, provide the original component model, product dimensions, terminal arrangement, and PCB layout. This information helps the engineering team assess compatibility and reduce the risk of mounting or electrical mismatches.
For volume orders, technical requirements can be reviewed before mass production. A sample evaluation is recommended when the component is used in a new circuit or as a replacement for an existing part.
Applications
The RC122N-H is intended for compact electronic control applications, particularly radio tuning. Potential applications include FM radio receivers, portable radios, tabletop radios, radio control panels, compact audio equipment, consumer electronics, electronic instruments, communication equipment, PCB-mounted control modules, and other devices requiring manual rotary adjustment. Its thin body is useful for equipment with limited installation depth. The horizontal PCB mounting arrangement supports integration into suitable circuit-board layouts. Final suitability depends on resistance, taper, rotational angle, terminal configuration, and mechanical dimensions, which should be checked against the requirements of the finished product.
