The **0JR-36-R** is a specific electronic component, typically categorized as a **Surface Mount (SMT) Fuse** or a **Zero-Ohm Jumper**, often manufactured by companies like Bel Fuse. Below is a detailed breakdown of its specifications, functionality, and technical characteristics. --- ### 1. Component Overview The "0JR" series usually denotes a **Zero-Ohm Jumper** in a resistor-style package. These are used to bridge connections on a Printed Circuit Board (PCB) where a standard trace cannot be used or where optional circuit configurations are needed. | Feature | Specification | | :--- | :--- | | **Type** | Zero-Ohm Jumper / Chip Resistor | | **Package Size** | 0603 (Inches) / 1608 (Metric) | | **Resistance** | < 0.05Ω (Maximum) | | **Current Rating** | Typically 1A to 2A (depending on thermal conditions) | | **Operating Temp** | -55°C to +155°C | | **Termination** | Matte Tin (Pb-Free) | ### 2. Part Number Breakdown While manufacturer codes vary slightly, the nomenclature generally follows this logic: * **0JR**: Series identifier (Zero-ohm Jumper Resistor). * **36**: Represents the packaging/quantity or a specific physical dimension code (often associated with 0603 sizing in specific catalogs). * **R**: Indicates compliance with **RoHS** (Lead-free) standards and "Tape & Reel" packaging. ### 3. Key Applications Electronic engineers use the 0JR-36-R for several practical reasons: 1. **PCB Configuration:** Acting as a "switch" that can be populated or left empty to enable/disable specific board features without redesigning the PCB. 2. **Crossover:** Jumping over another copper trace on a single-layer board. 3. **Automated Assembly:** Using a standard pick-and-place machine to install a jumper rather than using a manual wire link. ### 4. Technical Specifications Table | Property | Value | | :--- | :--- | | **Power Rating** | 0.1W (1/10 Watt) | | **Max DC Current** | 2.0 Amps | | **Dielectric Withstanding Voltage** | 100V - 500V (depending on substrate) | | **Composition** | Thick Film on Ceramic substrate | --- ### 5. Implementation Considerations * **Voltage Drop:** Even though it is "Zero-Ohm," there is a negligible resistance (usually <50mΩ). In high-precision analog circuits, this tiny voltage drop should be accounted for. * **Soldering:** Designed for Reflow or Wave soldering. The "R" suffix ensures the plating is compatible with modern lead-free solder pastes.
