Description


CCG81-2U 500PF-K 15KV-15KVA High Frequency High Voltage Ceramic Capacitor 80mm

High-performance ceramic capacitor for reliable industrial power solutions.

This product is a high-performance ceramic capacitor designed for high-frequency and high-voltage applications in the industrial sector. It is suitable for use in PLC systems and offers reliable power solutions for demanding industrial environments. The CCG81-2U model is optimized for efficiency and durability, ensuring optimal performance in challenging electrical conditions.

At a Glance: Engineer's Quick Brief

  • Exceptional RF Power Handling: Rated for a massive 15 KVA reactive power load, designed specifically to withstand the intense continuous AC currents found in high-frequency resonant tank circuits.
  • High Voltage Dielectric Strength: Features a robust 15KV DC rated voltage limit, utilizing low-loss Class 1/Class 2 ceramic dielectrics to prevent thermal runaway during continuous high-voltage operation.
  • Primary Application Focus: The industry standard for heavy-duty High-Frequency Induction Heating Machines, RF Broadcasting Transmitters, and Dielectric Welding Equipment.

Product Overview

The CCG81-2U 500PF-K 15KV-15KVA High-Frequency Ceramic Capacitor is a premium industrial passive component engineered for demanding radio frequency (RF) and high-voltage applications. With a physical diameter of 80mm, this "pot" or "disc" style capacitor provides a substantial surface area for natural air-cooling, ensuring optimal thermal dissipation under heavy reactive loads. The precisely formulated ceramic dielectric ensures an extremely low dissipation factor (tan δ), making it highly efficient when operating in resonant circuits for induction heaters or tube-based RF generators. The rugged threaded terminals allow for secure, low-resistance busbar connections, which are critical for minimizing $I^2R$ heating during high-current operations.

Technical Specifications & Nomenclature

Engineering Installation Note: When mounting this 80mm capacitor, ensure that the threaded terminal contacts are perfectly clean and tightened to the specified torque. Loose connections in high-frequency 15KVA circuits will rapidly generate contact resistance, leading to localized melting or catastrophic thermal fracturing of the ceramic body.

Industrial Application Matrix

The CCG81-2U series is specifically engineered for environments where standard capacitors would instantly fail due to internal dielectric heating:

  • Induction Heating & Melting: Serving as the primary resonant tank capacitor in solid-state (IGBT/MOSFET) or vacuum tube induction heaters.
  • Dielectric Welding: Providing the high-voltage RF energy required for plastic high-frequency welding machines.
  • RF Transmitters & Antenna Tuning: Utilized in broadcast engineering for coupling, bypassing, and antenna impedance matching networks.

Koeed RF Reactance & Max Current Calculator

To safely integrate this 500pF / 15KVA capacitor into your RF or induction circuit, you must ensure that the operating frequency does not cause the RF current to exceed the component's reactive power rating. Use this tool to calculate the capacitive reactance ($X_c$) and the theoretical maximum RMS current limit.

Engineering Troubleshooting & FAQ

1. Why does my CCG81-2U capacitor get excessively hot and eventually crack?
Ceramic cracking is almost always due to localized thermal shock. This occurs for three reasons: 1) The RF continuous current through the capacitor exceeds its 15 KVA reactive power rating at your specific frequency. 2) The mechanical terminal connections are slightly loose or oxidized, acting as a heating resistor. 3) Inadequate forced air cooling in tightly packed machine cabinets.
2. What does the "K" stand for in 500PF-K?
In standard electronic component nomenclature, the letter "K" indicates a capacitance tolerance of ±10%. This means the actual measured capacitance of the unit out of the factory will fall safely between 450 pF and 550 pF.
3. Can I use this 15KV capacitor for a DC high-voltage power supply filter?
Yes, it has an excellent 15KV DC dielectric strength. However, using a CCG81 series capacitor purely for DC filtering is often overkill and highly expensive. The primary engineering value and cost of this specific ceramic component lie in its 15 KVA AC reactive power handling capability, which standard DC filter capacitors do not possess.

Cross-Reference Guide

If you are upgrading an older induction heater or replacing parts on a legacy RF transmitter, the CCG81-2U series serves as a direct functional equivalent for numerous global high-frequency components. Always verify the overall diameter (80mm) and thread pitch before purchasing:

  • Vishay / Draloric Equivalents: Tos series or high-voltage RF power ceramic pot capacitors with matching 500pF / 15KV / ~15KVA ratings.
  • Highsky / HEC Equivalents: Standard Chinese replacements for High-Frequency welding machinery.
  • Form Factor Alternatives: If 80mm is too large for your chassis, you may need to evaluate water-cooled mica capacitors or array multiple lower-KVA rated capacitors in parallel, though this requires careful busbar inductance tuning.
