The part number **SCCO2A150D1B** typically refers to a **Surface Mount Device (SMD) Multilayer Ceramic Capacitor (MLCC)**, often associated with manufacturers like Walsin or similar passive component suppliers. Below is the technical breakdown of the specifications based on standard industry coding for this part series. --- ### 1. Technical Specifications | Parameter | Specification | Description | | :--- | :--- | :--- | | **Component Type** | MLCC | Multilayer Ceramic Chip Capacitor | | **Capacitance** | 15 pF | The "150" indicates 15 x 10^0 | | **Tolerance** | ±0.5 pF | Represented by the "D" suffix | | **Voltage Rating** | 100V DC | Represented by the "2A" code | | **Dielectric** | NPO (C0G) | Ultra-stable, low loss, 0±30 ppm/°C | | **Case Size** | 0805 (Metric 2012) | "CC" series often denotes standard sizing | | **Termination** | Ni/Sn | Nickel barrier with Tin plating (Lead-free) | --- ### 2. Breakdown of the Part Number The alphanumeric string follows a specific hierarchy used by manufacturers to define the physical and electrical characteristics: 1. **SC**: Series code (Standard General Purpose). 2. **CO (C0G)**: The temperature coefficient. C0G (NPO) means the capacitance does not change significantly with temperature. 3. **2A**: Voltage code. In standard EIA coding, `2A` corresponds to **100 Volts**. 4. **150**: Capacitance value. The first two digits are significant figures, and the third is the multiplier (15 x 10^0 = 15). 5. **D**: Tolerance code. For small values (under 10pF), this is often ±0.5pF. 6. **1**: Internal thickness/process code. 7. **B**: Packaging code (usually refers to Bulk or specific Reel size). --- ### 3. Key Applications Because this capacitor uses an **NPO/C0G** dielectric, it is designed for high-precision circuits where stability is critical. * **Resonant Circuits:** Used in LC oscillators and filter networks. * **RF/Wireless:** Ideal for high-frequency matching circuits due to low ESR (Equivalent Series Resistance). * **Timing Circuits:** Used where timing accuracy must remain constant despite temperature fluctuations. * **Decoupling:** High-voltage (100V) decoupling in sensitive analog stages. --- ### 4. Physical Dimensions (0805 Package) ```text Length (L): 2.00 ± 0.15 mm Width (W): 1.25 ± 0.10 mm Thickness: Depends on specific "1" code, usually ~0.6mm to 1.25mm ```
