150pF 3KV Ceramic Capacitor
The 150 Picofarad (pF) 3 Kilovolt (kV) Ceramic Capacitor is a specialized passive electronic component designed for high-voltage environments. It features a low capacitance value combined with a significantly high dielectric strength, defining its use in safety-critical and high-power applications.
Key Specifications and Characteristics
Capacitance (150 pF): This is a low capacitance value, making it suitable for high-frequency filtering, coupling, and tuning applications where a large energy storage capacity is not required.
Voltage Rating (3 kV): The most defining feature. This rating indicates the maximum DC voltage the capacitor can safely withstand continuously. This is crucial for applications involving main utility lines, flyback transformers, or specialized resonant circuits.
Dielectric Material (Ceramic): The ceramic dielectric material is non-polar, allowing it to be used in AC or DC circuits without orientation issues. High-voltage ceramic capacitors often use Class II (e.g., Z5U, X7R) or Class III (e.g., Y5V) dielectrics, though Class I (NP0/C0G) offers the best temperature stability but is less common at very high voltages.
Physical Form: Due to the high voltage requirements, these capacitors are typically large, bulky, and feature a thick epoxy or resin coating to prevent arcing and external surface leakage between the leads.
Primary Applications
High-Voltage Power Supplies: Used for filtering, bypassing, or decoupling in DC-DC converters, inverters, and high-voltage multiplier circuits.
Resonant Circuits: Ideal for RF transmitters, induction heaters, and plasma generators where high working voltage and high-frequency stability are required.
Safety and Suppression: Used in X-ray equipment, laser power supplies, and EMI/RFI suppression filters connected directly to the AC line.
