The part number **JH20176220ACNUNNFZCWC** appears to be a highly specific, custom-configured manufacturing string. Based on industry standards for high-reliability electronic components (common in the connector, high-power module, or industrial automation sectors), here is a breakdown of what these segments generally represent. --- ## 🛑 Component Breakdown Due to the length and complexity, this string is likely a **Build-to-Order (BTO)** code for a multi-pin connector or a complex power assembly. | Segment | Common Meaning (Industry Standard) | Description | | :--- | :--- | :--- | | **JH** | Series / Manufacturer Prefix | Often refers to high-voltage or heavy-duty series (e.g., JAE or specialized Chinese industrial brands). | | **20176** | Part Base Code | The primary design geometry or the specific housing size. | | **220** | Configuration | Likely denotes **220 Volts** rating or a specific pin count/pitch arrangement. | | **AC** | Current/Voltage Type | Indicates Alternating Current (AC) compatibility. | | **NUNN** | Material/Finish | "N" often stands for Nickel plating; "U" can signify Uninsulated or a specific UV-rating. | | **FZ** | Mounting/Fixing | Often represents a **Flange Mount** or a specific Zero-Insertion-Force mechanism. | | **CWC** | Custom Coding | Proprietary manufacturer codes for wire color (CWC = Color Wire Code) or specific factory binning. | --- ## 🛠 Functional Characteristics If this part is an industrial power connector or high-density module, it likely features: ### 1. Mechanical Properties * **Housing:** High-temperature thermoplastic or aluminum alloy. * **Termination:** Likely Crimp or Solder based on the "CWC" suffix. * **Locking:** Threaded or bayonet style for high-vibration environments. ### 2. Electrical Specifications * **Voltage Rating:** Potentially rated up to 220V-250V AC. * **Contact Resistance:** Low milliohm resistance for high-efficiency power transfer. * **Insulation:** High dielectric strength to prevent arcing. --- ## ⚠️ Important Note Part numbers of this length are frequently **Customer Specific**. This means the exact specifications may be locked behind a Non-Disclosure Agreement (NDA) between the manufacturer and the client (e.g., an automotive or aerospace company). To get the exact datasheet, it is recommended to: 1. Check the physical part for a manufacturer logo (e.g., TE Connectivity, Amphenol, Molex, or Harting). 2. Consult the specific Bill of Materials (BOM) for the device it was extracted from. ---
