The part number **296HC503C3N** typically identifies a specialized **high-frequency conduction-cooled capacitor**, often manufactured by companies like Illinois Capacitor (now part of Cornell Dubilier/CDE). These components are critical in high-power induction heating and resonance circuits. --- ### ## 1. Technical Specifications The following table outlines the primary electrical and physical characteristics of this component: | Parameter | Specification | | :--- | :--- | | **Capacitance** | 5.0 µF (Microfarads) | | **Voltage Rating** | 300 VAC (Maximum Working Voltage) | | **Tolerance** | ±10% (Commonly) | | **Maximum Current** | ~500 A (RMS) | | **Maximum Power** | ~300 kVAR (Reactive Power) | | **Frequency Range** | 100 kHz - 300 kHz (Varies by load) | | **Cooling Method** | Conduction Cooled (via mounting plates) | --- ### ## 2. Core Features * **Conduction Cooling:** Unlike standard capacitors that rely on air, these are designed to transfer heat through their metal terminals to a water-cooled bus bar or heat sink. * **Polypropylene Dielectric:** Uses low-loss self-healing polypropylene film, which is essential for handling high reactive power without melting. * **High Current Density:** The internal construction uses heavy-duty copper leads to minimize Internal Series Resistance (ESR). --- ### ## 3. Common Applications These capacitors are not found in consumer electronics; they are industrial-grade components used in: 1. **Induction Heating:** Used in the resonant tank circuit to melt metals or perform heat treatment. 2. **Wireless Charging:** High-power industrial wireless power transfer systems. 3. **Resonant Converters:** High-efficiency power supplies where Zero Voltage Switching (ZVS) is required. --- ### ## 4. Installation and Safety > **Warning:** These components handle lethal levels of current and voltage. * **Torque Requirements:** Terminals must be tightened to specific torque settings to ensure low contact resistance. * **Thermal Paste:** Often requires a thermal interface material between the capacitor base and the cooling plate. * **Discharge:** Must be fully discharged before handling, as they can store significant energy even after power is disconnected.
