The **5HF160-R** is a specific type of electronic component—specifically a **miniature cartridge fuse**. It belongs to the 5HF series, which is characterized by its high-breaking capacity and fast-acting response times. --- ## 1. Technical Specifications The following table summarizes the key electrical and physical characteristics of the 5HF160-R: | Parameter | Specification | | :--- | :--- | | **Component Type** | Cartridge Fuse | | **Current Rating** | 160mA (0.16A) | | **Voltage Rating (AC)** | 250V | | **Response Characteristic** | Fast-Acting (F) / Quick Acting | | **Dimensions** | 5mm x 20mm | | **Breaking Capacity** | 1500A @ 250V AC | | **Material** | Ceramic Tube with Silver-plated Brass Caps | | **RoHS Compliant** | Yes (indicated by the "-R" suffix) | --- ## 2. Key Features and Construction ### Ceramic Body Unlike glass fuses, the 5HF series uses a **ceramic tube**. Ceramic is used because it can withstand much higher internal pressures and temperatures. This allows the fuse to have a "High Breaking Capacity," meaning it can safely interrupt very high fault currents without the body of the fuse shattering. ### Fast-Acting (F) The "F" designation indicates that this fuse is designed to open very quickly when an overcurrent occurs. It does not have a "time-delay" mechanism, making it ideal for protecting sensitive electronic components like ICs and semiconductors that cannot survive even brief surges. ### The "-R" Suffix In the electronics industry, the "-R" at the end of a part number typically signifies **RoHS Compliance**. This means the part is manufactured without the use of hazardous substances like lead, cadmium, or mercury. --- ## 3. Applications The 5HF160-R is commonly found in the following environments: * **Power Supplies:** Protecting the input stage of small electronic devices. * **Test Equipment:** Safeguarding internal circuitry in multimeters and oscilloscopes. * **Industrial Controls:** Used in PLC modules where precise, low-current protection is required. * **Consumer Electronics:** Chargers and adapters for high-end audio/video equipment. --- ## 4.
