- Dielectric Withstand Voltage (DWV): 250% of rated voltage for 5 seconds, no breakdown or arcing observed
- Temperature Cycling: –55 °C ↔ +125 °C, 5 cycles, capacitance change ≤ ±0.5% or ±0.5 pF
- Steady-State Damp Heat Test: 85 °C / 85% RH, 240 hours, capacitance change ≤ ±0.3% or ±0.3 pF
- High-Temperature Load Life: 125 °C under 200% rated voltage for 2000 hours, capacitance change ≤ ±2% or ±0.5 pF, Q value > 1000
Performance Characteristics (Key Parameters)
- ESR vs. Capacitance: Exhibits low ESR (<0.1 Ω at high frequencies) across the capacitance range
- Q Factor vs. Capacitance: Maintains high Q values at elevated frequencies (typical Q > 1000)
- Self-Resonant Frequency (SRF/PRF):
- Horizontal Mounting: Influenced by substrate thickness and dielectric constant
- Vertical Mounting: Independent of substrate properties, determined solely by capacitor orientation
