The **MX2J10RE-R52** is a specific part number for a passive electronic component, typically identified as a **Metal Oxide Film Resistor**. This component is designed for high-stability applications and power handling in electronic circuits. ### Component Specifications | Feature | Specification | Description | | :--- | :--- | :--- | | **Component Type** | Metal Oxide Film Resistor | Provides high heat resistance and stability. | | **Resistance Value** | 10 $\Omega$ | Indicated by "10RE" (10 Ohms). | | **Tolerance** | $\pm$5% | Indicated by the "J" code. | | **Power Rating** | 2 Watts | Indicated by the "2" in the prefix (MX2). | | **Packaging** | Tape & Reel / Ammo Pack | The "R52" refers to 52mm lead spacing/taping. | --- ### Key Characteristics #### 1. Composition Metal Oxide Film resistors are made by coating a ceramic rod with a thin layer of tin oxide (or other metal oxides). This construction allows the part to withstand higher temperatures and provide better surge handling than standard Carbon Film resistors. #### 2. Thermal Stability These parts are designed to operate safely at high ambient temperatures. They are often "Flameproof," meaning they will not catch fire even if severely overloaded; they are designed to open the circuit safely. #### 3. Lead Spacing (R52) The **R52** suffix is a standard industry designation indicating that the component is supplied on a tape where the distance between the two tapes (the width) is exactly **52mm**. This is standard for automated "cut and bend" insertion machines used in mass production. --- ### Common Applications * **Power Supplies:** Used as a current limiting or "bleeder" resistor. * **Audio Equipment:** Employed in output stages where high power dissipation is required. * **Protective Circuits:** Used as a fuse-style resistor due to its flameproof coating. * **Industrial Controls:** Integrated into circuits that experience high thermal cycles. ---
