The **10PR-130-R** is a specific electronic component, typically categorized as a **Polymer Positive Temperature Coefficient (PPTC)** device, commonly known as a **Resettable Fuse**. ### 1. General Overview The 10PR-130-R is designed to protect electrical circuits from overcurrent conditions. Unlike traditional fuses that blow and must be replaced, this device "trips" (increases resistance) during a fault and resets once the power is removed and the fault is cleared. ### 2. Technical Specifications Below are the typical technical parameters associated with this part number (based on standard radial-leaded PPTC specifications): | Parameter | Specification (Typical) | | :--- | :--- | | **Type** | Polymer PTC (Resettable Fuse) | | **Hold Current ($I_{hold}$)** | 1.30 Amperes | | **Trip Current ($I_{trip}$)** | 2.60 Amperes | | **Max Voltage ($V_{max}$)** | 30V - 60V (Varies by series) | | **Max Current ($I_{max}$)** | 40A - 100A | | **Mounting Type** | Radial Through-Hole | | **Material** | Lead-free, RoHS Compliant | --- ### 3. How It Works The device functions based on its internal polymer structure: 1. **Normal State:** The conductive particles in the polymer form low-resistance chains, allowing current to flow easily. 2. **Fault State:** If the current exceeds the "Trip" limit, the polymer heats up and expands. This breaks the conductive chains, causing the resistance to spike dramatically and limiting the current to a safe level. 3. **Reset State:** Once the power is disconnected and the device cools down, the polymer contracts, the conductive chains re-form, and the device returns to a low-resistance state. ### 4. Common Applications * **Computer Peripherals:** USB ports and plug-and-play interfaces. * **Battery Packs:** Protection against short circuits during charging or discharging. * **Industrial Controls:** Protecting sensors and control circuits from wiring errors. * **Consumer Electronics:** Power supplies and motherboards. --- ### 5. Part Number Breakdown While naming conventions vary slightly by manufacturer (such as Bel Fuse, Littelfuse, or Bourns), the code generally follows this logic: * **10 / 0ZR:** Often refers to the product series or voltage rating category. * **130:** Represents the **Hold Current** (1.30 Amps). * **R:** Indicates **RoHS compliance** (Lead-Free).
