Based on the part number **SCCO2A150K1B**, this component is a **multilayer ceramic capacitor (MLCC)**. Below is a detailed breakdown of its technical specifications and physical characteristics. ### 1. Specification Breakdown The alphanumeric code follows standard industry nomenclature for capacitors (commonly associated with manufacturers like Walsin or similar passive component specialists). | Feature | Specification | Description | | :--- | :--- | :--- | | **Component Type** | Ceramic Capacitor | Multilayer Ceramic Chip Capacitor (MLCC) | | **Capacitance** | 15 pF | The "150" indicates 15 x 10^0 picofarads. | | **Tolerance** | ±10% | Represented by the letter 'K'. | | **Voltage Rating** | 100V | Represented by '2A' in the voltage code. | | **Dielectric** | COG / NPO | High stability, low loss, and zero temperature coefficient. | | **Case Size** | 0805 (Metric 2012) | Standard surface-mount dimensions. | --- ### 2. Technical Characteristics #### A. Dielectric Material (NPO/COG) The "C" in the prefix usually denotes a **COG (NPO)** dielectric. This is a Class I material, meaning: * **Temperature Stability:** The capacitance remains extremely stable across temperature changes (0 ±30 ppm/°C). * **Low Loss:** It has a high "Q" factor, making it ideal for high-frequency applications. * **No Aging:** Unlike Class II dielectrics (like X7R), COG capacitors do not lose capacitance over time. #### B. Capacitance Value * **Code:** 150 * **Calculation:** The first two digits (15) are the significant figures, and the third (0) is the multiplier (10^0). * **Result:** 15 pF. #### C. Voltage and Tolerance * **Voltage (2A):** Rated for a maximum working DC voltage of **100V**. * **Tolerance (K):** A standard industrial tolerance of **±10%**. While NPO capacitors often come in tighter tolerances (like J/±5%), 'K' is used for general-purpose filtering or tuning. --- ### 3. Common Applications Due to its stability and 100V rating, the **SCCO2A150K1B** is typically found in: 1. **RF Circuits:** Tuning and matching networks for high-frequency communication. 2. **Filtering:** Precision noise filtering in power supply lines. 3. **Timing Circuits:** Used in oscillators where timing precision is critical. 4. **Snubber Circuits:** Small-scale energy absorption in switching circuits. --- ### 4. Physical Dimensions (Typical 0805) | Dimension | Millimeters (mm) | Inches (in) | | :--- | :--- | :--- | | **Length (L)** | 2.00 ± 0.20 | 0.08 | | **Width (W)** | 1.25 ± 0.20 | 0.05 | | **Thickness (T)** | 0.80 ~ 1.25 | 0.03 ~ 0.05 |
