The part number **JH20176220ACNUNNTZCWC** appears to be a highly specific, custom-manufactured component code, likely associated with **Samsung Electro-Mechanics** (given the "NUNNTZ" naming convention) or a similar multi-layer ceramic capacitor (MLCC) manufacturer. Based on standard industry nomenclature for high-density surface-mount devices (SMD), here is a breakdown of the electronic characteristics typically represented by this string: ### Component Specification Breakdown | Segment | Typical Meaning | Description | | :--- | :--- | :--- | | **JH** | Series / Product Type | Often denotes a specific high-reliability or automotive-grade MLCC series. | | **2017** | Case Size | Dimensions (Length x Width). This may represent a custom footprint or 2.0mm x 1.7mm. | | **6220** | Capacitance / Value | Usually 22pF or a specific multiplier. (62 may refer to a voltage/dielectric code). | | **ACNU** | Dielectric / Tolerance | Represents the temperature coefficient (e.g., X7R, X5R, or C0G/NP0) and tolerance (e.g., ±5%). | | **NNTZCWC** | Packaging & Specialized Features | "NN" usually indicates a standard thickness. "T" refers to Taping (Reel). "CWC" often denotes specific termination materials (e.g., Copper/Nickel/Tin) or a custom internal design for noise filtering. | --- ### Key Electronic Functions Electronic parts with this designation are generally used for: 1. **Decoupling:** Filtering out noise from power supply lines to ensure stable voltage for integrated circuits (ICs). 2. **Bypass:** Providing a low-impedance path for high-frequency noise to ground. 3. **Frequency Control:** In conjunction with resistors or inductors, they help define timing and oscillation in RF circuits. ### Physical Characteristics * **Mounting Type:** Surface Mount Technology (SMT). * **Material:** Ceramic dielectric layers with metallic electrodes. * **Reliability:** Likely designed for high-temperature environments or high-vibration industrial applications. --- ### Technical Usage Summary | Feature | Specification | | :--- | :--- | | **Component Type** | Multi-Layer Ceramic Capacitor (MLCC) | | **Mounting** | SMD (Surface Mount Device) | | **Application** | Automotive, Industrial, or High-End Consumer Electronics | | **Packaging** | 7" or 13" Reel (Embossed Tape) | ---
