Based on the part number **DM05CC151DO3-SA-R02**, this component belongs to the **Mica Capacitor** family, typically manufactured by **Cornell Dubilier (CDE)**. These capacitors are known for their high stability, low loss, and reliability in RF applications. --- ### ## Technical Specifications | Parameter | Specification | Details | | :--- | :--- | :--- | | **Capacitance** | 150 pF | Indicated by "151" (15 x 10^1) | | **Tolerance** | ±0.5 pF | Indicated by "D" | | **Voltage Rating** | 500 VDC | Standard for DM05 series | | **Dielectric** | Silver Mica | Excellent for high-frequency stability | | **Package Type** | Radial Leaded | Standard dipped epoxy coating | | **Temperature Range** | -55°C to +125°C | Military/Industrial grade | --- ### ## Detailed Part Number Breakdown Understanding the nomenclature helps identify the exact physical and electrical properties: 1. **DM05**: Refers to the case size and style. "05" is a standard small-footprint dipped mica housing. 2. **CC**: Indicates the characteristic/temperature coefficient (standard for CDE mica). 3. **151**: The capacitance code. The first two digits (15) are significant, and the third (1) is the multiplier. 4. **D**: The tolerance code. For values below 10pF, it usually means ±0.5pF; for values above, it represents a very tight percentage tolerance. 5. **O3**: Typically relates to the lead spacing and lead material (e.g., copper-clad steel). 6. **SA-R02**: These are suffix codes for specific packaging (like Ammo Pack or Tape & Reel) and RoHS compliance/revision status. --- ### ## Key Features and Applications #### Features * **High Q Factor**: Very low losses at radio frequencies. * **High Stability**: Capacitance changes very little over time or with temperature fluctuations. * **Voltage Withstand**: High dielectric strength relative to its small size. #### Common Applications * **RF Oscillators**: Used in tuning circuits where frequency drift must be minimized. * **Filter Networks**: Excellent for high-precision low-pass or high-pass filters. * **Pulse Circuits**: Can handle high $dv/dt$ (rate of voltage change) without degradation. * **Audio Equipment**: Sometimes used in high-end audio for its linear characteristics. ---
