## HTB-38M-R Electronic Component Overview The **HTB-38M-R** is a specific model of a **Panel Mount Fuse Holder** manufactured by Eaton (formerly Bussmann). It is a passive electronic component designed to house, protect, and provide an electrical connection for a fuse within a circuit. ### Technical Specifications | Feature | Specification | | :--- | :--- | | **Component Type** | Fuse Holder | | **Fuse Size Accepted** | 5mm x 20mm | | **Current Rating** | 16 Amps (UL/CSA), 10 Amps (VDE) | | **Voltage Rating** | 250 Volts AC | | **Mounting Type** | Panel Mount (Nut secured) | | **Termination Style** | Right-Angle Solder / Quick Connect | | **Body Material** | High-temperature thermoplastic | | **Knob Type** | Screwdriver slotted / Finger grip | --- ### Key Electronic & Structural Features #### 1. The Conductive Path The internal parts are made of high-conductivity copper alloy, often tin-plated. This ensures low resistance and prevents excessive heat buildup during high-current operation. #### 2. Termination (The "R" Suffix) The **"R"** in the part number typically signifies **Right-Angle terminals**. In electronic design, this is critical for: * **Space Management:** Allowing wires to be connected parallel to the panel to save depth. * **PCB Integration:** Making it easier to solder directly to a board if the panel is mounted close to the circuitry. #### 3. Insulation and Safety * **Dielectric Strength:** Designed to withstand over 1500V to prevent arcing between the live terminal and the chassis. * **Inflammability:** The plastic housing is usually rated **UL 94V-0**, meaning it is self-extinguishing and resistant to high heat caused by potential overcurrent faults. #### 4. Bayonet-Style Knob The electronic connection is secured via a spring-loaded bayonet knob. This ensures a constant mechanical pressure between the fuse caps and the holder terminals, maintaining a stable electrical contact even under vibration. --- ### Applications * **Power Supplies:** Used as the primary input protection. * **Industrial Equipment:** Protecting internal logic boards from external surges. * **Medical Devices:** Ensuring safe failure modes in sensitive electronics.
