RE50E821MDN1

The RE50E821MDN1 is a conductive polymer aluminum solid electrolytic capacitor from Nichicon's RE5 series. It delivers ultra-low ESR and low impedance in a compact, low-profile φ8 radial-can package, engineered for general-purpose and high-frequency applications.

With 820 µF capacitance at 2.5 V, high ripple capability, and a wide operating temperature range, the RE50E821MDN1 is suited to designs that require robust AC performance and compact through-hole mounting.

Key Features

• Capacitance & Voltage — 820 µF nominal capacitance rated at 2.5 V with ±20% tolerance, suitable for bulk and smoothing roles in low-voltage designs.
• Ultra-low ESR — 5 mΩ equivalent series resistance measured at 100 kHz, providing low loss and low impedance at high frequencies.
• High ripple current — Rated ripple handling of 630 mA at 120 Hz and 6.3 A at 300 kHz (frequency-dependent), supporting demanding AC conditions.
• Compact, low-profile package — φ8 × 8 mm radial can with 3.5 mm lead spacing, enabling space-constrained through-hole layouts.
• Operating range & endurance — Specified for −55°C to +105°C with a rated lifetime of 2000 hours at 105°C under rated voltage.
• Polarized radial-lead design — Robust can-style package for reliable through-hole mounting in general-purpose assemblies.
• RoHS compliant — Meets RoHS environmental requirements.

Typical Applications

• High-frequency power stages — Use where low ESR and low impedance at hundreds of kilohertz are required to manage switching ripple and maintain power integrity.
• General-purpose power filtering — Bulk smoothing and decoupling in low-voltage, high-current circuits benefiting from high ripple capability and compact size.
• Compact through-hole assemblies — Space-constrained boards that require a low-profile radial capacitor with reliable leaded mounting.
• Embedded and industrial electronics — Circuits needing stable performance across −55°C to +105°C and endurance at elevated temperature.

Unique Advantages

• Low-impedance performance: 5 mΩ ESR at 100 kHz reduces AC losses and supports effective decoupling at high frequencies.
• High-frequency ripple handling: Frequency-rated ripple current up to 6.3 A at 300 kHz enables operation in high-switching-rate environments.
• Space-efficient form factor: φ8 × 8 mm can and 3.5 mm lead spacing provide a low-profile solution for through-hole designs.
• Thermal and endurance specification: −55°C to +105°C operating range with 2000 hours endurance at 105°C for predictable life in elevated-temperature applications.
• Conductive polymer electrolyte: Solid polymer construction yields low ESR and low impedance characteristics useful for high-frequency circuits.
• Regulatory compliance: RoHS status ensures compatibility with common environmental requirements.
