RL80J821MDN1

The RL80J821MDN1 is a conductive polymer solid electrolytic aluminum capacitor in a low-profile radial lead can (φ8×8 mm). It delivers 820 µF capacitance at a 6.3 V rating with a compact footprint and is offered in mass production packaging (Bulk / Bag Packing).

Designed for general-purpose electronics, this part combines low equivalent series resistance and strong ripple-current handling with an extended operating range (−55°C to 105°C) and 2000 hours endurance at 105°C, making it suitable for board-level power applications where space and thermal reliability matter.

Key Features

• Dielectric / Construction Conductive polymer solid electrolytic capacitor in a radial lead can package (φ8×8 mm).
• Capacitance & Tolerance 820 µF nominal with tolerance −20% to +20% (measured at 120 Hz, 20°C).
• Rated Voltage 6.3 V DC rating for low-voltage board power rails.
• Low ESR 8 mΩ equivalent series resistance at 20°C / 100 kHz for reduced loss and improved transient response.
• High Ripple Current Low-frequency ripple current 570 mA (120 Hz) and high-frequency ripple current 5.7 A (300 kHz) support demanding power-filtering tasks.
• Dissipation Factor tanδ = 0.12 (measured at 20°C, 120 Hz) for predictable AC performance.
• Leakage Current Specified leakage current of 1033 µA (after 2 minutes at rated voltage, 20°C).
• Temperature & Endurance Operating range −55°C to 105°C with a rated load life of 2000 hours at 105°C.
• Package & Mounting Radial lead mounting with 3.5 mm lead spacing (±0.5 mm). Package case: radial can, lead form: bulk (no terminal forming) options available.
• Environmental RoHS compliant.

Typical Applications

• General Purpose Electronics Suited for a wide range of board-level applications where a compact, radial conductive polymer capacitor is required.
• Power Filtering and Decoupling Low ESR (8 mΩ) and high ripple-current capability make it appropriate for power-filtering and decoupling on low-voltage rails.
• Space-Constrained Designs Low-profile φ8×8 mm package and 3.5 mm lead spacing fit tight PCB layouts while maintaining performance.

Unique Advantages

• Low power dissipation: 8 mΩ ESR at 100 kHz reduces losses and thermal rise in high-frequency applications.
• High ripple tolerance: Rated ripple currents (570 mA at 120 Hz, 5.7 A at 300 kHz) enable effective smoothing on switching supplies and converters.
• Compact, low-profile package: φ8×8 mm can and radial leads minimize board area while preserving capacitance.
• Broad temperature range: −55°C to 105°C supports designs that experience wide thermal environments.
• Proven endurance: 2000 hours at 105°C provides defined life expectations for elevated-temperature operation.
• Regulatory readiness: RoHS compliant for regulatory and manufacturing consistency.
