The **C515-5-R** is a specific electronic component belonging to the **Time-Delay Glass Tube Fuse** family, manufactured by **Eaton (Bussmann Series)**. It is widely used in power supplies, monitors, and consumer electronics to protect against overcurrent conditions. --- ### 1. Technical Specifications The following table summarizes the key electrical and physical characteristics of the C515-5-R: | Parameter | Specification | | :--- | :--- | | **Manufacturer** | Eaton / Bussmann | | **Current Rating** | 5 Amperes (5A) | | **Voltage Rating** | 250 VAC | | **Fuse Type** | Time-Delay / Slow-Blow | | **Form Factor** | 2AG / 5mm x 15mm | | **Body Material** | Glass Tube | | **Termination Style** | Axial Lead (Through-hole) | | **Interrupting Rating** | 200A at 250VAC | --- ### 2. Key Features and Components * **Time-Delay Function:** This is a "Slow-Blow" fuse. Unlike fast-acting fuses, it is designed to withstand short-duration high-current surges (like motor start-ups or capacitor charging) without blowing. * **Axial Leads:** The "-R" suffix indicates that the fuse includes wire leads soldered to the end caps. This allows the part to be soldered directly onto a Printed Circuit Board (PCB) rather than being placed in a fuse holder. * **Glass Construction:** The transparent body allows for visual inspection of the internal element to confirm if the fuse has blown. * **Compact Size:** The 5x15mm dimensions are smaller than the standard 3AG (6x32mm) fuses, making it ideal for compact electronic assemblies. --- ### 3. Part Number Breakdown Understanding the nomenclature helps in identifying variants: ```text C515 - 5 - R | | | | | └── Lead Configuration (Axial Leads/RoHS Compliant) | └────── Amperage Rating (5 Amps) └──────────── Series Name (5x15mm Time-Delay) ``` --- ### 4. Typical Applications The C515-5-R is commonly found in: 1. **Switching Power Supplies:** To handle the inrush current during startup. 2. **LED Lighting:** Protecting drivers from internal faults. 3. **Consumer Electronics:** Chargers, adapters, and small appliances. 4. **Industrial Controls:** Low-voltage control circuits requiring space-saving protection.
