The **MA14FCD-R** belongs to a specialized series of high-frequency, high-reliability capacitors, typically associated with **Passive Plus, Inc. (PPI)** or similar manufacturers specializing in RF/Microwave components. These parts are engineered for demanding applications like telecommunications, medical electronics (MRI), and military hardware. --- ### 1. Technical Specifications The part number follows a specific nomenclature that defines its electrical characteristics: | Parameter | Specification | Description | | :--- | :--- | :--- | | **Series** | MA Series | High-Q, Low ESR NPO/COG Dielectric | | **Case Size** | 14 | Refers to the physical dimensions (Approx. 0.110" x 0.110") | | **Capacitance** | FCD | Coding for specific picofarad (pF) values | | **Tolerance** | - | Usually specified by a letter (e.g., B=±0.1pF, C=±0.25pF) | | **Voltage** | - | High voltage rating (often up to 500V - 2500V) | | **Termination** | -R | RoHS Compliant (Lead-Free) | ### 2. Key Features * **High Q Factor:** Extremely low losses at high frequencies, ensuring signal integrity in RF circuits. * **Ultra-Low ESR:** Low Equivalent Series Resistance prevents overheating and power loss. * **Temperature Stability:** Uses **NPO (COG)** dielectric, meaning the capacitance remains stable across a wide temperature range (typically -55°C to +125°C). * **High Self-Resonance:** Ideal for bypass, coupling, and tuning in the GHz range. ### 3. Common Applications These components are not standard consumer-grade capacitors; they are found in: 1. **RF Power Amplifiers:** Used for matching networks. 2. **MRI Coils:** High-voltage stability is required for medical imaging. 3. **Satellite Communications:** Reliable performance in extreme environments. 4. **Antenna Systems:** Tuning and filtering for base stations. ### 4.
