Key Features

• Capacitance & Voltage — 39 µF rated capacitance at 20 V, with tolerance ±20% measured at 120 Hz, 20 °C.
• Low ESR and High Ripple Capability — ESR of 45 mΩ at 100 kHz and ripple current ratings of 1 A at 120 Hz and 2 A at 100 kHz support effective power filtering and transient suppression.
• Long Life & Endurance — Endurance specification: 20,000 hours at 105 °C with defined limits on capacitance change, tan δ and ESR after the endurance test.
• Automotive-Grade Reliability — AEC-Q200 qualified and specified for operation from −55 °C to +105 °C.
• Surface-Mount Chip Package — Chip-type, SMD radial can construction sized L: 7 × D: 8 mm with recommended land pattern L: 8.3 × W: 8.3 mm for PCB mounting.
• Soldering Robustness — Compatible with lead-free reflow soldering; datasheet specifies resistance to soldering heat and recommended reflow profiles.
• Environmental Compliance — RoHS compliant per the provided product information.

Typical Applications

• Automotive electronic control units (ECUs) — Low ESR and high ripple current capability make this capacitor suitable for power decoupling and local energy storage in automotive modules.
• Power supply filtering — Compact chip form factor and stable performance across −55 °C to +105 °C support bulk and post-regulator filtering in demanding environments.
• DC-DC converters and voltage regulators — High ripple current rating and low ESR help reduce output voltage ripple and improve transient response in compact power stages.

Unique Advantages

• Proven long-life reliability: 20,000 hours at 105 °C provides predictable lifetime behavior for long-term deployments.
