## Analysis of FPK-R-1.6A Electronic Component The **FPK-R-1.6A** is a specific type of electronic protection component, primarily identified as a **Radial Lead Micro Fuse**. These are designed to provide overcurrent protection in space-constrained applications. --- ### Technical Specifications | Parameter | Specification | | :--- | :--- | | **Component Type** | Micro Fuse (Radial Lead) | | **Current Rating** | 1.6 Amperes (A) | | **Voltage Rating** | Typically 250V AC | | **Mounting Type** | Through-hole (Radial) | | **Body Material** | Thermoplastic (usually UL 94 V-0 rated) | | **Response Characteristic** | Fast-Acting or Time-Lag (Depends on specific sub-series) | | **Standard Compliance** | IEC 60127-3 or UL 248-14 | --- ### Key Features 1. **Small Form Factor:** The "Micro" or "Subminiature" design allows it to occupy minimal PCB real estate compared to traditional glass tube fuses. 2. **Radial Leads:** The pins extend from the bottom of the cylindrical or rectangular body, allowing for vertical insertion into printed circuit boards. 3. **Low Internal Resistance:** Designed to minimize power dissipation during normal operation. 4. **Sealed Construction:** Most versions are epoxy-sealed or plastic-molded, making them resistant to board washing processes and environmental contaminants. --- ### Common Applications * **Power Supplies:** Used in AC/DC adapters and switching power supplies (SMPS). * **Consumer Electronics:** Found in LED lighting drivers, chargers, and television sets. * **Industrial Equipment:** Protection for control circuits and small motors. * **Battery Chargers:** Protecting the charging path from short circuits. --- ### Identification Guide When replacing or sourcing this part, pay attention to the prefix and suffix: * **FPK:** Generally refers to the series (Fast/Slow acting characteristics). * **R:** Often denotes "Radial" leads or "RoHS" compliance. * **1.6A:** The maximum continuous current the fuse can handle before blowing.
