The part number **10TK-516-R** typically refers to a high-quality **Mica Capacitor**, often manufactured by companies like *Cornell Dubilier (CDE)* or specialized precision capacitor firms. These components are known for their high stability, low loss, and reliability in RF (Radio Frequency) applications. --- ### 1. Technical Specifications Based on standard naming conventions for this series, here is the breakdown of the technical characteristics: | Property | Specification | Description | | :--- | :--- | :--- | | **Capacitance** | 510 pF (or specific to sub-code) | Determined by the "516" numerical code. | | **Voltage Rating** | 1000V (10 kV potential) | "10TK" often denotes high voltage capability. | | **Tolerance** | ±2% to ±5% | Precision rating for frequency-sensitive circuits. | | **Dielectric Material** | Silver Mica | Provides excellent temperature coefficient stability. | | **Termination** | Radial Leaded | Standard through-hole mounting. | | **RoHS Status** | Compliant ("-R") | The suffix "-R" usually indicates lead-free/RoHS compliance. | --- ### 2. Key Features * **Temperature Stability:** Mica capacitors have a very low temperature coefficient, meaning their capacitance does not change significantly with heat. * **Low Dissipation Factor:** They exhibit very low energy loss, making them ideal for high-Q (Quality factor) circuits. * **High Voltage Resistance:** Due to the natural insulating properties of mica, these parts can handle high voltage spikes without dielectric breakdown. * **Longevity:** They are highly resistant to aging and chemical degradation. --- ### 3. Common Applications Mica capacitors like the 10TK series are found in specialized electronics where precision is more important than size: 1. **RF Transmitters:** Used in tuning circuits and filters where frequency drift must be minimized. 2. **Audio Equipment:** Occasionally used in high-end vacuum tube amplifiers for coupling or tone stacks. 3. **Test Equipment:** Found in calibration tools and signal generators. 4. **Pulse Power:** Used in circuits requiring rapid discharge without internal heating. --- ### 4.
