RL80G821MCN1

The RL80G821MCN1 is a conductive polymer aluminum electrolytic capacitor in Nichicon's RL8 series. It delivers 820 µF capacitance at a 4 V rating in a low-profile radial lead package (φ8×8 mm), designed for general-purpose electronic designs.

Key value comes from its low equivalent series resistance and high ripple current capability, combined with a compact footprint and long life at elevated temperatures, making it suited where dense power decoupling and reliable low-voltage energy storage are required.

Key Features

• Capacitance and Voltage — 820 µF rated capacitance at 4 V provides substantial bulk capacitance for low-voltage rails; capacitance tolerance is ±20%.
• Low ESR — ESR of 6 mΩ measured at 100 kHz (20°C) supports efficient high-frequency performance and reduced heat generation.
• High Ripple Current — Rated for 610 mA at 120 Hz and 6.1 A at 300 kHz, enabling robust handling of both low- and high-frequency ripple conditions.
• Compact, Low-Profile Package — φ8×8 mm radial can with 3.5 mm lead spacing and radial lead mounting for through-hole assembly where board height is constrained.
• Wide Temperature Range and Longevity — Operating range of −55°C to +105°C with a rated load life of 2000 hours at 105°C.
• Polarized, Radial-Lead Construction — Polarized capacitor in a radial lead can package compatible with standard through-hole mounting and lead-free flow soldering conditions.
• RoHS Compliant — Conforms to RoHS directive requirements.

Typical Applications

• Power supply decoupling — Bulk and high-frequency decoupling for low-voltage rails in general-purpose electronics where low ESR and high ripple handling are required.
• Energy storage for power rails — Local energy reservoir for transient load support in compact, through-hole designs.
• General-purpose electronic assemblies — Through-hole power and smoothing applications in consumer, industrial, and instrumentation equipment classified as general purpose.

Unique Advantages

• Low ESR for improved efficiency: 6 mΩ ESR at 100 kHz reduces losses and thermal stress under high-frequency operation.
• High ripple capability: Rated ripple currents up to 6.1 A at 300 kHz allow handling of demanding switching and high-frequency ripple conditions.
• Space-efficient low profile: φ8×8 mm can and 8 mm height provide a compact solution for constrained board height without sacrificing capacitance.
• Robust temperature performance: −55°C to +105°C operating range and 2000 hours life at 105°C support long-term reliability in elevated-temperature environments.
• Through-hole radial mounting: 3.5 mm lead spacing and radial leads simplify placement and soldering in through-hole assemblies.
