The **DM05CC102DO3-SA-R02** is a specialized high-voltage mica capacitor. It is designed for applications requiring high stability, precision, and low loss at high frequencies. --- ### 1. Technical Specifications Below are the primary parameters for this specific component: | Parameter | Value / Detail | | :--- | :--- | | **Capacitance** | 1000 pF (1.0 nF) | | **Tolerance** | ±0.5 pF (or ±0.5% depending on series revision) | | **Voltage Rating** | 300V to 500V (Standard for DM05 series) | | **Dielectric Material** | Silver Mica | | **Operating Temperature** | -55°C to +125°C | | **Termination Style** | Radial Leaded | | **Case Type** | Dipped (Epoxy Coating) | --- ### 2. Breakdown of Part Number While nomenclature varies slightly by manufacturer (often Cornell Dubilier or similar), the coding generally follows this logic: * **DM05**: Refers to the physical size and case style (Miniature Dipped Mica). * **CC**: Temperature coefficient characteristic. * **102**: Capacitance code (10 + two zeros = 1000pF). * **D**: Tolerance code (often signifies ±0.5% or a specific picofarad deviation). * **O3**: Voltage rating indicator. * **SA-R02**: Specific packaging or RoHS compliance suffix. --- ### 3. Key Characteristics * **High Stability:** Mica capacitors are known for having almost no capacitance change over time or under varying voltage/temperature. * **Low Dissipation Factor:** They exhibit very low loss, making them ideal for high-Q circuits. * **Precision:** Unlike ceramic capacitors which can drift significantly, silver mica provides tight tolerances. --- ### 4. Typical Applications These parts are rarely used in general power filtering; they are reserved for precision timing and RF circuits: 1. **RF Oscillators:** Maintaining a stable frequency. 2. **Filter Networks:** Used in tuned high-frequency circuits. 3. **Transmitters:** Handling reactive power in radio equipment. 4. **Pulse Circuits:** Due to their ability to handle high dV/dt (voltage spikes). ---
