The **AS30-R10K-RC** is a precision rotary potentiometer manufactured by **Bourns**. It is part of the AS series, designed for high-reliability applications where precise control and a long rotational life are required. --- ### ## Technical Specifications Below are the primary electrical and mechanical characteristics for the AS30-R10K-RC: | Feature | Specification | | :--- | :--- | | **Resistance Value** | 10k Ohms (indicated by "10K") | | **Resistance Tolerance** | ±10% or ±20% (Standard) | | **Power Rating** | 0.2 Watts | | **Rotational Life** | Up to 100,000 cycles | | **Operating Temperature** | -40°C to +125°C | | **Termination Style** | PC Pins (Through-hole mounting) | | **RoHS Status** | Compliant (indicated by "RC") | --- ### ## Key Components & Design #### 1. Resistive Element The part uses a **Conductive Plastic** element. Unlike carbon film, conductive plastic provides a much smoother output, lower noise during rotation, and a significantly longer operational life, making it suitable for industrial sensors. #### 2. The "RC" Suffix In Bourns nomenclature, **RC** stands for **RoHS Compliant**. This indicates that the component is manufactured without lead or other restricted hazardous substances, meeting international environmental standards. #### 3. Mechanical Interface * **Rotary Action:** It features a continuous or limited turn (depending on the specific sub-model) to adjust the voltage divider ratio. * **Form Factor:** The AS30 series typically features a 9mm or 12mm square body designed for space-constrained PCB layouts. --- ### ## Common Applications The AS30-R10K-RC is frequently found in professional-grade equipment, including: * **Medical Equipment:** Precise adjustment of parameters in diagnostic tools. * **Industrial Controls:** Calibration of sensors or set-point adjustments. * **Professional Audio:** High-end mixing consoles where durability and low noise are critical. * **Test & Measurement:** Used as a user-interface knob for high-precision laboratory gear. --- ### ## Part Number Breakdown * **AS30:** Series designation (Conductive Plastic Potentiometer). * **R:** Terminal or Taper style (typically Linear for this series). * **10K:** Resistance value (10,000 Ohms). * **RC:** RoHS Compliant.
