RS80E821MDNASQ

The RS80E821MDNASQ is a conductive polymer aluminum solid electrolytic capacitor from Nichicon's RS8 series, optimized for compact, high-performance power decoupling in general-purpose electronic designs. Its combination of low ESR/ESL, high ripple-current capability and a low-profile radial-can package delivers reliable bulk and high-frequency filtering in space-constrained assemblies.

Designed for demanding thermal environments, this radial-lead capacitor supports continuous operation from -55°C to 105°C and a specified load life of 5000 hours at 105°C, making it suitable for long-life general-purpose applications.

Key Features

• Conductive polymer solid electrolyte Provides low equivalent series resistance (ESR) and reduced ESL for improved high-frequency performance.
• High capacitance in a compact package 820 µF rated capacitance at 2.5 V in a φ6.3 × 8 mm can for dense PCB layouts.
• Low ESR ESR of 7 mΩ measured at 100 kHz (20°C), enabling lower loss and better voltage stability under load.
• High ripple-current capability Rated ripple current of 560 mA at 120 Hz and 5.6 A at 300 kHz to support both low- and high-frequency switching environments.
• Robust thermal endurance Load life: 5000 hours at 105°C; operating temperature range -55°C to 105°C for extended reliability.
• Radial lead package φ6.3×8 mm can with 2.5 mm lead spacing for through-hole mounting; compatible with lead-free flow soldering conditions.
• RoHS compliant Conforms to the RoHS directive (2011/65/EU, (EU)2015/863).
• Polarized device Designed for DC applications requiring polarized electrolytic capacitance. Tolerance: -20% to +20%.

Typical Applications

• General-purpose electronic circuits — Bulk energy storage and decoupling where a compact, high-capacitance polarized capacitor is required.
• Power-supply filtering — Supports ripple suppression in switching regulators and DC power rails thanks to low ESR and high ripple-current ratings.
• High-frequency switching stages — Low ESR/ESL and a specified ripple current at 300 kHz make it suitable for high-frequency converter outputs.

Unique Advantages

• Low-loss power handling: 7 mΩ ESR at 100 kHz reduces conductive losses and heat generation in power rails.
• Wide ripple-frequency support: Rated ripple current values at both 120 Hz and 300 kHz cover a broad range of switching and AC conditions.
• Space-efficient form factor: φ6.3 × 8 mm radial can and 2.5 mm lead spacing deliver high capacitance in a low-profile package.
• Long-term thermal reliability: 5000-hour load life at 105°C provides predictable aging performance in elevated-temperature environments.
• Assembly-friendly: Radial lead design compatible with lead-free flow soldering conditions simplifies through-hole assembly processes.
• Regulatory compliance: RoHS conformity supports environmentally regulated product designs.
