The **10JR-36-R** is a specific electronic component, typically categorized as a **Wirewound Precision Resistor**. It is part of a series often manufactured by companies like Ohmite or similar industrial component suppliers. Below is a detailed breakdown of its specifications and characteristics. --- ### 1. Component Specifications The nomenclature "10JR-36-R" usually follows a specific coding standard for power resistors: | Feature | Specification | Description | | :--- | :--- | :--- | | **Component Type** | Wirewound Resistor | Constructed by winding metal wire on an insulating core. | | **Resistance Value** | 0.36 $\Omega$ | The "36" indicates the numerical value, often with a multiplier. | | **Power Rating** | 10 Watts | Capable of dissipating 10W of heat under standard conditions. | | **Tolerance** | ±5% (Typical) | Standard tolerance for the "J" series designation. | | **RoHS Status** | Compliant (-R) | The suffix "-R" usually indicates lead-free/RoHS compliance. | ### 2. Physical Construction * **Core:** Usually a ceramic or alumina core for high thermal stability. * **Winding:** A resistive alloy wire (like Nichrome) is wound around the core. * **Coating:** Typically encapsulated in a vitreous enamel or silicone ceramic coating to protect against moisture and oxidation. * **Mounting:** Axial leads (meant to be soldered through holes in a PCB or mounted via terminals). ### 3. Key Applications Because of its high power rating (10W) and wirewound nature, the 10JR-36-R is used in specific circuit scenarios: 1. **Current Sensing:** Low resistance values (0.36 Ohms) are ideal for measuring current flow by monitoring the voltage drop across the resistor. 2. **Inrush Current Limiting:** Used to protect circuits from spikes when power is first applied. 3. **Braking Resistors:** Used in small motor control circuits to dissipate kinetic energy. 4. **Voltage Division:** In high-power power supply units (PSUs). --- ### 4. Comparison: Wirewound vs. Metal Film | Feature | Wirewound (10JR-36-R) | Metal Film | | :--- | :--- | :--- | | **Power Handling** | Very High | Low to Medium | | **Inductance** | Higher (due to coils) | Very Low | | **Stability** | Excellent at high temps | Moderate | | **Pulse Handling** | Excellent | Poor |
