Based on standard electronic component naming conventions, the code **C3-R22-10** typically refers to a **Power Resistor** or a specific type of **Capacitor**, depending on the manufacturer (most commonly associated with brands like TE Connectivity or generic industrial classifications). Below is a breakdown of what these parts represent in an electronic context. --- ## 1. Component Identification In the majority of industrial parts catalogs, this nomenclature is broken down as follows: | Segment | Meaning | Description | | :--- | :--- | :--- | | **C3** | Series/Case Size | Often denotes a specific physical housing or power rating (e.g., 3 Watts). | | **R22** | Resistance Value | The "R" acts as a decimal point. **R22 = 0.22 Ohms**. | | **10** | Tolerance | Typically represents a **±10%** deviation from the nominal value. | --- ## 2. Technical Specifications If this is a standard **0.22Ω Power Resistor**, the technical attributes generally include: ### Physical Characteristics * **Mounting Type:** Through-hole or Axial leaded. * **Coating:** Often Silicone or Flameproof Ceramic coating to handle high heat. * **Material:** Usually Wirewound (for high precision/power) or Metal Oxide. ### Electrical Characteristics * **Resistance:** 0.22 Ω (Low resistance, often used for current sensing). * **Power Rating:** Likely 3 Watts (indicated by the 'C3' prefix in many catalogs). * **Tolerance:** J (±5%) or K (±10%). In this specific code, **10** stands for 10%. * **Temperature Coefficient:** Typically 200ppm/°C to 400ppm/°C. --- ## 3. Common Applications Parts with these specifications (low resistance, high power) are used in: 1. **Current Sensing:** Placed in series with a load to measure voltage drop and determine current flow. 2. **Inrush Limiting:** Used to protect circuits from a sudden surge of electricity when powered on. 3. **Voltage Division:** Used in power supply circuits to drop specific small voltages. 4. **Audio Amplifiers:** Frequently found in the output stages of amplifiers to stabilize the circuit. --- ## 4. Alternative Interpretation: Capacitors If the part is a **Ceramic Capacitor** (less common for this specific string but possible in certain Japanese naming conventions): * **C3:** Case size or Dielectric type. * **R22:** 0.22 microfarads (µF). * **10:** 10 Volts. *Note: If you have a specific manufacturer name (like Ohmite, Vishay, or TE), I can provide the exact datasheet parameters.*
