The **MHO+26FCG-R** is a specific part number typically associated with **MHO (Metal Hybrid Oxide) Power Resistors**, often manufactured by companies like Royal Ohm or similar electronic component suppliers. These are specialized resistors designed for high-power applications where stability and space-saving are critical. --- ### 1. Key Technical Specifications Based on the standard nomenclature for this series, here is a breakdown of its electronic characteristics: | Parameter | Specification (Typical) | | :--- | :--- | | **Type** | Metal Hybrid Oxide / Power Resistor | | **Power Rating** | 2 Watts (Standard for the '2' or '26' prefix in this series) | | **Resistance Value** | Defined by the "FCG" code (often 10Ω to 100kΩ range) | | **Tolerance** | ±1% or ±5% (depending on the 'F' or 'J' designator) | | **Operating Temp** | -55°C to +155°C | | **Coating** | Flameproof Silicone/Cement | --- ### 2. Part Number Breakdown While manufacturer codes vary slightly, the "MHO+26FCG-R" generally follows this logic: * **MHO**: Series Name (Metal Hybrid Oxide). These resistors use a metal film or oxide layer on a ceramic core, optimized for heat dissipation. * **26**: Often refers to the physical size or power rating (e.g., 2 Watts with a specific body length). * **F**: Tolerance code (F = ±1%). * **CG**: Resistance value code. In many systems, "C" represents a multiplier and "G" represents the base value. * **-R**: Indicates compliance with **RoHS** standards (Lead-free). --- ### 3. Key Electronic Features 1. **Non-Flammability**: The "FCG" variants are usually coated with a flameproof material that will not emit smoke or ignite even if the resistor is overloaded. 2. **Surge Handling**: Metal Oxide resistors are superior to Carbon Film resistors in handling high-voltage surges and pulses. 3. **Low Noise**: They exhibit low thermal noise, making them suitable for audio and precision power circuits. 4. **Stability**: High stability against environmental humidity and temperature fluctuations. --- ### 4. Common Applications * **Power Supplies**: Used as bleeder resistors or in current-limiting stages. * **Consumer Electronics**: Found in TVs and household appliances where safety (flameproof) is a priority. * **Industrial Controls**: Used in motor controllers and signal conditioning where power dissipation is required in a small footprint.
