The **5MFP 700-R** is a specific type of electronic component—specifically a **fuse**. It belongs to the "5MFP" series, which are fast-acting, pigtail-lead, glass tube fuses. Below is a detailed breakdown of its electronic characteristics and specifications. --- ## 1. Technical Specifications The part number "5MFP 700-R" encodes its specific operating parameters. | Parameter | Specification | | :--- | :--- | | **Component Type** | Fast-Acting Fuse (Glass Tube) | | **Current Rating** | 700 mA (0.7 Amps) | | **Voltage Rating (AC)** | 250V AC | | **Mounting Style** | Through-Hole (Pigtail Leads) | | **Size / Dimension** | 5mm x 20mm | | **Termination** | Axial (Wire leads soldered to end caps) | | **RoHS Status** | Compliant (indicated by the "-R" suffix) | --- ## 2. Key Electronic Features ### A. Fast-Acting Characteristic The "5MFP" series is designed to open (blow) quickly when an overload occurs. Unlike "Slow-Blow" fuses, these do not tolerate brief surges or inrush currents. This makes them ideal for protecting sensitive semiconductor devices and printed circuit boards (PCBs). ### B. Axial Pigtail Leads Unlike standard cartridge fuses that snap into a fuse clip, the 5MFP 700-R has **pigtail leads**. * **Direct Soldering:** It is designed to be soldered directly onto a PCB. * **Space Saving:** Eliminates the need for bulky fuse blocks or clips. ### C. Construction * **Body:** Transparent glass tube allows for easy visual inspection to see if the internal element has melted. * **End Caps:** Nickel-plated brass for high conductivity and corrosion resistance. * **Lead Material:** Tin-plated copper. --- ## 3. Part Number Decoder Understanding the nomenclature helps in identifying equivalent parts: * **5MFP:** The Series Name (5x20mm, Fast-acting, Pigtail). * **700:** The Current Rating (700 milliamps). * **-R:** RoHS (Restriction of Hazardous Substances) Compliant (Lead-free). --- ## 4. Common Applications Because of its 700mA rating and fast response time, this part is typically found in: 1. **Power Supplies:** Secondary side protection for low-power circuits. 2. **Consumer Electronics:** Chargers, adapters, and small appliances. 3. **Industrial Equipment:** Control circuits where precise current limits are required. 4. **Lighting Ballasts:** Protection against short circuits in LED or fluorescent drivers. ---
