The part number **10TK-026-R** typically refers to a high-voltage, surface-mount ceramic capacitor, often manufactured by companies like **Holy Stone Enterprise**. These components are specifically designed for power supply circuits and lighting ballasts. --- ### 1. Technical Specifications The breakdown of the part's characteristics is as follows: | Feature | Specification | | :--- | :--- | | **Component Type** | Multilayer Ceramic Capacitor (MLCC) | | **Capacitance Value** | 0.022µF (22nF) | | **Voltage Rating** | 1000V (1kV) | | **Tolerance** | ±10% (K) | | **Dielectric Material** | X7R (Stable temperature coefficient) | | **Package / Case** | 1812 (4532 Metric) | | **Termination** | RoHS Compliant (R - Lead-Free) | --- ### 2. Key Internal Features * **Dielectric Material (X7R):** This is a "temperature stable" ceramic. It operates from -55°C to +125°C with a maximum capacitance change of ±15%. * **High Voltage Architecture:** The internal electrodes are designed with a specific overlap pattern to prevent arcing and withstand high potential differences across the ceramic layers. * **Termination:** Usually features a "Soft Termination" or standard tin-over-nickel barrier to ensure solderability and mechanical strength. --- ### 3. Common Applications Due to its high voltage rating and compact 1812 footprint, it is commonly used in: 1. **DC-DC Converters:** Input/Output filtering in industrial power modules. 2. **Inverters:** Snubber circuits to protect switches from voltage spikes. 3. **LED Lighting:** Used in the driver stages where high-line voltages are present. 4. **Modems/Telecom:** Isolation and surge protection. --- ### 4. Handling and Safety * **Voltage Stress:** Ensure the operating voltage does not exceed 1000V. Continuous operation at the limit can shorten the component's lifespan. * **Thermal Shock:** Like all MLCCs, this part is sensitive to rapid temperature changes during soldering (Reflow/Wave). Pre-heating is essential to avoid micro-cracks.
