RS80J821MDN1

The RS80J821MDN1 from Nichicon is a conductive polymer aluminum solid electrolytic capacitor in a radial-lead can, offering 820 µF capacitance at a 6.3 V rating. It is part of the RS8 series, designed for low ESR/ESL and high ripple-current capability in a compact, low-profile φ6.3×8 mm package.

Targeted for general-purpose electronics, this capacitor suits applications that require compact bulk capacitance with robust ripple handling and a wide operating temperature range of −55 °C to 105 °C.

Key Features

• Capacitance & Voltage — 820 µF nominal capacitance with a rated voltage of 6.3 V and tolerance of −20% to +20%, providing predictable bulk energy storage for low-voltage designs.
• Low ESR — ESR of 8 mΩ measured at 20 °C / 100 kHz, enabling reduced power loss and improved transient response in high-frequency circuits.
• High Ripple Current — Low-frequency ripple current of 470 mA (120 Hz) and high-frequency ripple current of 4.7 A (300 kHz) for effective smoothing in switching power stages.
• Low Profile Package — Compact φ6.3×8 mm can with 2.5 mm lead spacing (±0.5 mm) and radial lead mounting for through-hole PCB implementations where board space is constrained.
• Thermal & Lifetime — Wide operating temperature range of −55 °C to 105 °C and rated life/endurance of 2000 hours at 105 °C for reliable performance under elevated temperatures.
• Electrical Quality — Loss tangent (tan δ) of 0.1 measured at 20 °C / 120 Hz and specified leakage current of 1291 µA, allowing designers to balance ESR, ripple handling, and standby leakage budgets.
• Compliance & Availability — RoHS compliant and in mass production; packaging available in bulk (no terminal forming) or bag packing to support volume assembly workflows.

Typical Applications

• Compact Power Supplies — Bulk smoothing and output filtering for compact DC–DC converters that require high ripple current capability in a low-profile package.
• PCB Decoupling — Local energy storage and decoupling on power rails in embedded systems and consumer electronics where space and thermal margin are limited.
• High-Frequency Switching Stages — Support for switching power stages and regulators operating at high frequencies, leveraging low ESR at 100 kHz and high-frequency ripple ratings.

Unique Advantages

• Compact bulk capacitance: 820 µF in a φ6.3×8 mm can reduces board area for required energy storage compared with larger form factors.
• Improved thermal handling: Rated for −55 °C to 105 °C with a 2000-hour life at 105 °C, suitable for designs exposed to elevated operating temperatures.
• High-frequency performance: 8 mΩ ESR at 100 kHz and a 4.7 A ripple current rating at 300 kHz enable efficient filtering in high-speed switching applications.
• Through-hole robustness: Radial lead form and standard 2.5 mm lead spacing simplify prototyping and mechanical reliability for board-level assemblies.
• Supply readiness: RoHS compliant and in mass production with bulk/bag packing options to support volume sourcing and manufacturing workflows.
