PCK0J821MCO1GS

The PCK0J821MCO1GS from Nichicon is a conductive polymer aluminum solid electrolytic chip-type capacitor in an SMD can package. It delivers ultra-low ESR and high capacitance in a surface-mount form factor designed for demanding electronics applications.

With an 820 µF capacitance at 6.3 V, AEC-Q200 qualification, RoHS compliance, lead-free reflow compatibility to a 260°C peak, and a rated load life of 2000 hours at 105°C, this part targets applications that require sustained ripple handling and high reliability in compact assemblies.

Key Features

• Conductive polymer chemistry  Provides stable, solid electrolyte performance as a chip-type aluminum capacitor.
• Capacitance & voltage  820 µF rated capacitance at 6.3 V with ±20% tolerance (at 120 Hz, 20°C).
• Ultra-low ESR  9 mΩ equivalent series resistance measured at 100 kHz, 20°C for improved AC performance.
• High ripple current capability  Rated for 2.5 A at 20 Hz and 5 A at 100 kHz to handle high ripple and dynamic load conditions.
• High-temperature endurance  Load life rated 2000 hours at 105°C; endurance and damp-heat characteristics specified in the series datasheet.
• SMD, lead-free reflow compatible  Designed for surface-mount assembly with lead-free reflow soldering profile allowance up to a 260°C peak (single reflow at 260°C).
• Automotive-grade qualification  AEC-Q200 Qualified and listed for Automotive applications in the product data.
• Operating temperature range  Specified from −55°C to +105°C to cover broad environmental conditions.
• Compact package  Radial, can-type SMD package with physical dimensions L: 0.8 × D: 1 cm and recommended land size L: 1.03 × W: 1.03 cm.

Typical Applications

• Automotive electronics  Suited for automotive modules where AEC-Q200 qualification, long load life at elevated temperature, and RoHS compliance are required.
• On-board power modules  Used in surface-mount power designs that demand high ripple current handling and low ESR for stable voltage regulation.
• Compact SMD assemblies  Provides high capacitance in a chip-type SMD can for designs constrained by board space but requiring robust AC performance.

Unique Advantages

• Low ESR for improved AC performance: 9 mΩ at 100 kHz reduces impedance in high-frequency circuits and supports cleaner power rails.
• High ripple tolerance: Rated ripple currents of 2.5 A (20 Hz) and 5 A (100 kHz) enable effective handling of dynamic loads and switching noise.
• Long high-temperature life: 2000 hours at 105°C provides extended endurance where sustained elevated-temperature operation is required.
• Automotive qualification: AEC-Q200 qualification aligns the part with automotive reliability expectations and selection criteria.
• Lead-free reflow compatible: Specified reflow tolerance to a 260°C peak facilitates integration into modern Pb-free assembly processes.
• High capacitance in a compact SMD can: 820 µF in a chip-type package enables reduced BOM and space-efficient board layouts.
