RNU0G821MCN1

The RNU0G821MCN1 is a conductive polymer aluminum solid electrolytic capacitor offering 820 µF capacitance at a 4 V rating in a radial lead can package. Designed for general-purpose electronic uses, it provides high capacitance with low equivalent series resistance and elevated ripple-handling capability.

Key value propositions include low ESR (7 mΩ at 100 kHz), high rated ripple current across frequency (570 mA at 120 Hz; 5.7 A at 300 kHz), wide operating temperature range (−55 °C to 105 °C) and a 2000-hour lifetime at 105 °C, all in a compact radial-lead form factor with 3.5 mm lead spacing.

Key Features

• Dielectric / Construction Conductive polymer aluminum solid electrolytic design providing high capacitance in a compact can-style radial lead package.
• Capacitance & Tolerance 820 µF nominal capacitance with ±20% tolerance (measured at 120 Hz, 20 °C).
• Low ESR ESR specified at 7 mΩ (measured at 100 kHz, 20 °C), supporting high-frequency performance and efficient energy transfer.
• High Ripple Current Rated ripple current of 570 mA at 120 Hz and 5.7 A at 300 kHz, enabling effective smoothing and decoupling in power circuits.
• Temperature & Reliability Operating range −55 °C to 105 °C with a load life specified at 2000 hours at 105 °C under rated voltage conditions.
• Mechanical / Mounting Radial lead can package with 3.5 mm lead spacing for through-hole mounting and robust PCB anchoring.
• Regulatory RoHS compliant.

Typical Applications

• General-purpose power filtering — Use where high capacitance and low ESR are required to smooth supply rails and reduce voltage ripple.
• DC–DC converter output smoothing — Suitable for converter outputs that demand compact bulk capacitance with strong ripple-handling capability.
• Decoupling in power subsystems — Provides bulk decoupling for boards and modules operating across −55 °C to 105 °C.

Unique Advantages

• High capacitance in a compact radial can: 820 µF of capacitance delivered in a small package to save PCB area while maintaining bulk storage.
• Low loss at high frequency: 7 mΩ ESR at 100 kHz minimizes power dissipation and improves converter efficiency under high-frequency switching.
• Strong ripple tolerance: Rated ripple currents up to 5.7 A at 300 kHz support demanding switching applications and reduce thermal stress.
• Wide operating temperature: −55 °C to 105 °C operation enables deployment across a broad range of environmental conditions.
• Designed for endurance: Specified 2000-hour lifetime at 105 °C for predictable behavior in elevated-temperature applications.
• RoHS compliance: Meets lead-free and restricted-substance requirements for modern product designs.
