• Low Capacitance: 100 pF (marked 101) for high‑frequency stability.
• Ceramic Dielectric: Ensures minimal loss and high insulation resistance.
• Radial Leads: Easy through‑hole PCB mounting.
• Epoxy Coating: Protects against moisture and mechanical stress.

Technical Specifications:

• Capacitance: 100 pF (±10 %)
• Rated Voltage: 3 kV DC
• Dissipation Factor: ≤ 0.1 % (at 1 kHz)
• Insulation Resistance: ≥ 10 GΩ (at 500 V)
• Temperature Coefficient: ±30 ppm/°C (typical, NP0)
• Operating Temperature Range: ‑25 °C to +85 °C

Mechanical Specifications:

• Disc Diameter: ≈ 13 mm
• Disc Thickness: ≈ 5 mm
• Lead Spacing: 7.5 mm (typical)
• Lead Diameter: 0.6 mm (tinned copper)
