100pF 101 3kV High Voltage Ceramic Disc Capacitor

100pF 101 3kV High Voltage Ceramic Disc Capacitor is a robust, non-polarized component engineered to operate reliably in circuits subjected to elevated voltages. Marked typically as “101” for its 100 pF capacitance, this capacitor provides crucial high-voltage isolation and stability, preventing dielectric breakdown in demanding power applications. Therefore, designers specifically utilize this component for filtering, coupling, and suppression tasks where standard low-voltage capacitors would fail. Furthermore, its ceramic dielectric offers inherent low loss and high insulation resistance, making it an ideal choice for high-frequency and high-energy systems. You can confidently integrate this 3kV capacitor into your design to ensure superior noise reduction and long-term performance stability.

Key Features:

• High Voltage Rating: The capacitor reliably withstands a DC working voltage of 3 kV (3000 V), consequently providing maximum safety margin in high-potential circuits.
• Low Capacitance (100 pF): This low value capacitor is perfect for high-frequency resonance, coupling, or bypassing applications where stray capacitance must remain minimal.
• Non-Polarized: You can install the component in either direction without concern for polarity, simplifying assembly and circuit design.
• Ceramic Dielectric: The ceramic material ensures excellent frequency characteristics, low dissipation factor (< 0.1%), and high insulation resistance (≥ 10 GΩ).
• Through-Hole Design: Radial leads simplify mounting and soldering into standard printed circuit boards (PCBs).

Pinout and Wiring:

• Terminal 1 & 2: The capacitor connects directly across the circuit nodes requiring filtering, coupling, or voltage division.
• Polarity: This is a non-polarized component, meaning the orientation of the leads in the circuit does not affect performance.
• Installation Note: However, for safety, maintain maximum possible clearance and creepage distance between the capacitor leads and other low-voltage traces on the PCB.
• Usage: Connect the component across the high-voltage line and ground for decoupling, or between two stages for DC blocking/AC coupling.
