The **FCE-1A-R** is an electronic component primarily classified as a **Fuse Clip** or fuse holder accessory, typically manufactured by companies like **Eaton (Bussmann Series)**. It is designed to securely hold and provide an electrical connection for standard 1/4" (6.3mm) diameter cylindrical fuses. --- ### Technical Specifications The following table highlights the primary electrical and physical characteristics of the FCE-1A-R: | Parameter | Specification | | :--- | :--- | | **Component Type** | Fuse Clip | | **Fuse Diameter** | 1/4" (6.3mm) | | **Current Rating** | Up to 15A (Typical) | | **Material** | Spring Bronze or Beryllium Copper | | **Plating** | Tin-plated | | **Mounting Type** | PCB Mount (Through-hole) | | **Orientation** | Vertical / End-stop clip | --- ### Key Electronic & Structural Features #### 1. Material Composition The clip is usually made from **Spring Bronze**. This alloy is chosen for its excellent "spring" memory, ensuring that even after multiple fuse replacements, the clip maintains a tight mechanical grip on the fuse to prevent high-resistance contact points. #### 2. Tin Plating The surface is treated with **Bright Tin plating**. This serves two purposes: * **Solderability:** Ensures a strong, reliable bond when soldering the clip to a Printed Circuit Board (PCB). * **Corrosion Resistance:** Protects the base copper alloy from oxidation, maintaining low contact resistance over time. #### 3. End-Stop Design The "1A" designation often refers to the specific physical configuration. These clips usually feature an **End-stop (Ear)**, which acts as a physical barrier. This prevents the fuse from sliding out of position longitudinally during high-vibration environments. #### 4. Through-Hole Leads The part features sturdy metal tabs (leads) designed to be inserted into pre-drilled holes on a PCB. This provides both the electrical path and the mechanical anchoring required to withstand the force of inserting or removing a fuse. --- ### Application Use Cases * **Power Supplies:** Providing overcurrent protection on the input or output stage. * **Industrial Controls:** Allowing for easy field replacement of blown fuses without soldering. * **Consumer Electronics:** Used in devices where space is available for 1/4" glass or ceramic fuses (like the AGC or ABC series). ---
