RS80E821MDN1

The RS80E821MDN1 is a conductive polymer aluminum solid electrolytic capacitor in a low-profile radial-lead can. It delivers 820 µF at 2.5 V with low ESR/ESL and high ripple-current capability for general-purpose low-voltage power applications.

Designed for compact, space-constrained assemblies, this radial-lead capacitor combines a φ6.3×8 mm package and 2.5 mm lead spacing with a wide operating temperature range and defined load life at elevated temperature.

Key Features

• Conductive polymer aluminum construction — Solid electrolyte design for stable electrical performance and reduced ESR compared with traditional wet electrolytics.
• Capacitance and voltage — 820 µF rated capacitance at a 2.5 V rating with ±20% tolerance.
• Low ESR / ESL — ESR specified at 7 mΩ measured at 100 kHz (20°C), supporting low-loss operation in high-frequency circuits.
• High ripple current — Rated ripple current of 560 mA at 120 Hz and 5.6 A at 300 kHz to handle AC stress in power stages and decoupling roles.
• Compact radial package — Low-profile φ6.3 × 8 mm can with 2.5 mm lead spacing, radial-lead mounting for through-hole or hybrid assemblies.
• Temperature and life — Operating temperature range –55°C to +105°C with a rated load life of 2000 hours at 105°C.
• Polarity — Polarized device suitable for electrolytic capacitor use cases.
• RoHS compliant — Meets RoHS directive requirements.

Typical Applications

• General-purpose low-voltage power filtering — Bulk smoothing and decoupling for 2.5 V rails where high capacitance and low ESR are required.
• Compact power modules — Space-sensitive applications that benefit from the low-profile φ6.3×8 mm can and 2.5 mm lead spacing.
• High-frequency power stages — Use where high ripple-current capability and low ESR at 100 kHz to 300 kHz improve stability and reduce losses.

Unique Advantages

• High capacitance in a small footprint: 820 µF in a φ6.3×8 mm package enables significant bulk capacitance without large board area.
• Low ESR for improved efficiency: 7 mΩ (100 kHz) ESR helps minimize I²R losses and voltage ripple in tight power budgets.
• Wide temperature tolerance: –55°C to +105°C operation supports designs exposed to broad thermal environments.
• Defined elevated-temperature life: 2000 hours at 105°C provides a verifiable endurance metric for thermal-stressed designs.
• High ripple capability across frequencies: Rated ripple current figures (560 mA at 120 Hz, 5.6 A at 300 kHz) allow confident use in both low- and high-frequency applications.
• RoHS compliance: Conforms to RoHS requirements for regulatory alignment in assembly processes.
