Key Features

• Core Technology Conductive polymer aluminum solid electrolyte construction for stable capacitive performance and low ESR.
• Electrical Performance 120 µF capacitance with ±20% tolerance and rated to 80 V; ESR specified at 18 mΩ (100 kHz, 20°C).
• High Ripple Capability Rated ripple current of 1.25 A at 120 Hz and 2.5 A at 100 kHz to support power conversion and decoupling tasks.
• Thermal and Endurance Operating range −55°C to +125°C with endurance specified as 4000 hours at 125°C under rated voltage.
• Package and Mounting Surface-mount, radial can SMD package with compact footprint (L 1.6 cm × D 1.0 cm) and recommended land size L 1.03 × W 1.03 cm.
• Manufacturing Compatibility Lead‑free reflow soldering compliant with peak 260°C conditions for standard PCB assembly processes.
• Quality and Compliance AEC‑Q200 qualified and RoHS compliant for regulated and automotive-grade applications.

Typical Applications

• Automotive electronics — Suitable for automotive electronic modules that require AEC‑Q200 qualification and long-term high-temperature endurance.
• High-voltage power rails — 80 V rating supports smoothing and decoupling on elevated DC bus and power-supply rails.
• Compact power modules — Low ESR and high ripple-current capability in an SMD can package enable use in space-constrained DC‑DC converters and power stages.
• Harsh-temperature environments — Rated operation to 125°C and 4000‑hour endurance at 125°C for applications exposed to sustained high temperatures.

Unique Advantages

• Low ESR for improved transient response: 18 mΩ (100 kHz) ESR reduces voltage ripple and improves regulator stability in high-frequency power circuits.
• High ripple-current handling: 1.25 A (120 Hz) and 2.5 A (100 kHz) ratings support continuous ripple loads in power-conversion applications.
• High-voltage capability: 80 V rating enables use on elevated DC buses without series stacking or extra components.
• Long high-temperature life: 4000 hours at 125°C provides predictable longevity for designs exposed to sustained heat.
• Automotive-grade qualification: AEC‑Q200 qualification supports deployment in automotive and other reliability-focused designs.
• SMD, reflow-compatible packaging: Radial can SMD form factor and 260°C peak reflow compatibility streamline automated assembly.
