Key Features

• Capacitance & Voltage: 820 µF rated capacitance at 2.5 V with tolerance ±20%, providing bulk energy storage in a compact SMD package.
• Low ESR & High Ripple Handling: ESR of 17 mΩ measured at 20°C, 100 kHz, with ripple current ratings of 2.2 A at 120 Hz and 4.4 A at 100 kHz—optimized for high-frequency decoupling and power-stage filtering.
• Low Loss (tan δ): tanδ of 0.12 (measured at 20°C, 120 Hz) for stable performance in AC conditions.
• Long Load Life: Load life of 2000 hours at 105°C, with defined endurance limits for capacitance, tanδ and ESR as specified after the endurance test.
• Wide Temperature Range: Rated for operation from -55°C to +105°C to support demanding thermal environments.
• Automotive-Grade Qualification: AEC-Q200 qualification for use in automotive applications.
• Soldering & Assembly Friendly: SMD construction compatible with lead-free reflow soldering; series guidance supports peak reflow up to 260°C under specified conditions.
• Package & Handling: φ10 × 8L can-style SMD with embossed carrier taping and moisture-proof packing for automated assembly.
• Regulatory: RoHS compliant.

Typical Applications

• Automotive Power Modules: Bulk storage and high-frequency decoupling for in-vehicle power rails and power-conversion stages, leveraging AEC-Q200 qualification.
• DC–DC Converters: Output filtering and ripple suppression where low ESR and high ripple-current capability are required.
• Power Management for Embedded Systems: Local energy buffering and transient support in compact surface-mount designs.

Unique Advantages

• High ripple capacity with low ESR: 17 mΩ ESR and ripple ratings up to 4.4 A at 100 kHz enable efficient suppression of switching noise and reduced thermal stress in power stages.
