The **MHO+66FBG-R** is a specific part number typically associated with **SMD (Surface Mount Device) high-precision resistors**, often part of the MHO series manufactured by companies like **KOA Speer** or similar specialty resistor firms. These are designed for high-stability and precision applications. --- ### 1. Technical Specifications Table Based on the standard nomenclature for the MHO series, here are the general technical parameters: | Feature | Specification | | :--- | :--- | | **Component Type** | Metal Film Precision Resistor | | **Mounting Style** | Surface Mount (SMD/SMT) | | **Resistance Value** | Typically 6.6 kΩ (based on "66" coding) | | **Tolerance** | ±0.1% to ±1% (F usually denotes 1%) | | **Power Rating** | 0.25W to 0.5W (varies by package size) | | **Temperature Coefficient** | ±25 ppm/°C to ±100 ppm/°C | | **Operating Temp Range** | -55°C to +155°C | --- ### 2. Breakdown of the Part Number While manufacturers have slight variations, the suffix and prefix usually break down as follows: * **MHO:** Series identifier (Metal Film, High Stability, Often Molded). * **66:** Numerical resistance code. * **F:** Tolerance code (F = ±1%). * **BG:** Packaging or Temp Coefficient indicator (often denotes Bulk or specific Tape & Reel). * **R:** RoHS Compliant (Lead-free). --- ### 3. Key Features * **High Reliability:** Designed to withstand environmental stress and maintain a stable resistance value over time. * **Low Noise:** Metal film construction provides much lower thermal noise compared to standard thick-film carbon resistors. * **Precision:** Used in circuits where exact voltage division or current sensing is required. --- ### 4. Common Applications Due to its precision nature, this component is found in: 1. **Medical Instrumentation:** For accurate sensor readings. 2. **Industrial Controls:** In feedback loops for motor controllers. 3. **Telecommunications:** Signal processing and filtering. 4. **Test & Measurement:** Multimeters and oscilloscopes. --- ### 5. Sample Footprint Representation If you are designing a PCB (Printed Circuit Board), the footprint usually follows standard EIA sizes (like 1206 or 2512): ```c // Typical SMD Land Pattern (Dimensions in mm) [Pad] --- 1.5mm gap --- [Pad] Width: 1.6mm Length: 3.2mm (for 1206 package) ```
