The **BK/PCC-1-R** is a specific model of subminiature fuse manufactured by **Eaton (formerly Bussmann)**. It belongs to the **PC-Tron** series, which is highly regarded in the electronics industry for its high-speed performance and reliability on printed circuit boards (PCBs). --- ### 1. Technical Specifications The following table outlines the primary electrical and physical characteristics of the BK/PCC-1-R: | Parameter | Specification | | :--- | :--- | | **Series** | PC-Tron | | **Current Rating** | 1 Ampere | | **Voltage Rating (AC)** | 250 VAC | | **Voltage Rating (DC)** | 125 VDC | | **Interrupting Rating** | 50A at 250VAC / 10kA at 125VAC | | **Mounting Type** | Through-Hole (Radial Leads) | | **Response Time** | Fast-Acting | | **Body Material** | High-temperature plastic | | **Lead Finish** | Tin-plated copper | --- ### 2. Breakdown of the Part Number Understanding the nomenclature helps in identifying the specific variant: * **BK/**: Indicates "Bulk" packaging (usually 100 or 1,000 units per box). * **PCC**: Refers to the physical lead configuration (Radial leads, typically 0.100" spacing). * **1**: Represents the Ampere rating (1A). * **-R**: Signifies **RoHS Compliance** (lead-free and environmentally friendly). --- ### 3. Key Features and Applications The BK/PCC-1-R is not a standard glass fuse; it is a specialized component designed for precision protection. #### Features: * **High Interrupting Capacity:** Unlike many small fuses, the PC-Tron series can handle high fault currents (up to 10,000 Amps at certain voltages) without exploding or leaking. * **Compact Footprint:** Its subminiature size saves significant board space compared to traditional 5x20mm fuse holders. * **Speed:** It is "Fast-Acting," meaning it blows almost instantly when a current spike occurs, protecting sensitive semiconductors (ICs, MOSFETs). #### Common Applications: * Power supplies (SMPS) * Consumer electronics * Industrial control boards * Telecommunications equipment --- ### 4. Installation and Handling When integrating this part into a circuit, developers should note the lead spacing and soldering requirements: ```text Lead Spacing: 0.100" (2.54mm) Soldering: Wave solder compatible Orientation: Vertical (Radial) ``` ---
