The **C-36-R** typically refers to a specific series of **high-voltage, high-frequency ceramic power capacitors** often used in industrial induction heating, broadcast transmitters, and medical equipment (like MRI scanners). These are "Doorknob" style capacitors designed to handle significant reactive power. Below is a breakdown of the electronic specifications and components of these parts. --- ## 1. Technical Specifications Table Typical values for a C-36-R series capacitor (variations exist based on the specific capacitance value): | Property | Specification | | :--- | :--- | | **Dielectric Material** | Class 1 Ceramic (N750, N2200, or R-series) | | **Voltage Rating** | 5kV to 15kV (Peak) | | **Capacitance Range** | 100pF to 2500pF | | **Frequency Range** | 100 kHz to 30 MHz | | **Power Rating** | 10 kVAR to 50 kVAR (Reactive Power) | | **Mounting Style** | Screw Terminal (Doorknob) | --- ## 2. Key Electronic Components & Construction ### A. Ceramic Dielectric The core of the C-36-R is a high-purity ceramic disc. Unlike standard capacitors, these use **Class 1 dielectrics**, which offer: * **Low Dissipation Factor:** Minimal energy loss as heat during high-frequency cycles. * **Temperature Stability:** Capacitance remains stable even as the part heats up during operation. ### B. Electrode Coating The surfaces of the ceramic are usually coated with **fired-on silver**. This ensures a low-resistance path for high RF currents, preventing localized "hot spots" that could crack the ceramic. ### C. Terminals (The "R" Designation) The "R" in the part number often indicates the terminal configuration or a specific revision of the hardware: * **Material:** Usually silver-plated brass or copper for maximum conductivity. * **Thread Type:** Typically metric or imperial internal threads for heavy-duty busbar mounting. --- ## 3. Common Applications Because the C-36-R is designed to handle **kVAR** (Kilovolt-Amperes Reactive) rather than just simple DC voltage, it is found in: 1. **Induction Heating:** Used in the tank circuit to resonate with the induction coil. 2. **RF Matching Networks:** Helping match the impedance of an RF generator to a load. 3. **Antenna Phasing:** Used in high-power AM/FM broadcast towers. --- ## 4. Usage Precautions ```cpp // Cautionary Note on Power Handling if (Operating_Frequency > Limit || Voltage > Rating) { Thermal_Runaway = true; Component_Failure = "Mechanical Cracking"; } ``` * **Cooling:** In high kVAR applications, these parts may require forced air cooling. * **Torque:** When mounting, excessive torque on the screw terminals can stress and crack the ceramic body.
