RS80J821MCN1

The RS80J821MCN1 is a conductive polymer aluminum solid electrolytic capacitor in Nichicon’s RS8 series. It is a low‑profile, radial‑lead component designed for general‑purpose power decoupling and bulk energy storage in compact assemblies.

Key attributes include an 820 µF capacitance at 6.3 V, very low ESR/ESL, lead‑free flow soldering compatibility, and RoHS compliance—making it suitable for designs that require high ripple handling in a small radial can package.

Key Features

• Electrical Performance — 820 µF capacitance at 6.3 V with ±20% tolerance, polarized design for DC applications.
• Low ESR / ESL — ESR specified as 8 mΩ at 100 kHz (20°C), supporting high ripple current and improved dynamic performance.
• High ripple capability — Rated ripple current of 470 mA at 120 Hz and 4.7 A at 300 kHz; frequency coefficients show 1.00 at 100 kHz and 300 kHz for full ripple rating at those frequencies.
• Compact, low‑profile package — Radial can with dimensions φ6.3 × 8 mm (L × D) and 2.5 mm lead spacing for space‑constrained layouts.
• Wide operating temperature — Specified for −55°C to +105°C operation, with endurance testing at 105°C.
• Reliability / Lifetime — Load life rated to 2000 hours at 105°C under rated voltage conditions.
• Assembly & Compliance — Radial lead type compatible with lead‑free flow soldering conditions; compliant to RoHS (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑purpose power filtering — Local decoupling and bulk filtering where compact size and low ESR improve transient and ripple performance.
• Switching regulator output capacitors — Supports high ripple currents at switching frequencies (100 kHz–300 kHz) thanks to low ESR and favorable frequency coefficients.
• Compact electronic modules — Small φ6.3 × 8 mm can and low seated profile fit space‑restricted boards requiring robust decoupling.

Unique Advantages

• Low ESR for improved ripple handling: 8 mΩ at 100 kHz reduces power loss and temperature rise under high AC stress.
• High frequency performance: Frequency coefficient = 1.00 at 100 kHz and 300 kHz, enabling rated ripple capability at common switching frequencies.
• Small footprint, low profile: φ6.3 × 8 mm radial can with 2.5 mm lead spacing saves board area while maintaining through-hole robustness.
• Designed for elevated operating temperatures: Rated for −55°C to +105°C with a 2000‑hour endurance at 105°C for predictable long‑term behavior.
• Lead‑free flow compatible and RoHS compliant: Simplifies assembly for lead‑free production flows and regulatory compliance.
