RL80E821MDNASQ

The RL80E821MDNASQ is a conductive polymer aluminum solid electrolytic capacitor designed for general-purpose electronic applications. It combines ultra-low ESR and high ripple-current capability in a compact, low-profile φ8×8 radial-can package.

This part is optimized for compact power circuitry where low impedance, high ripple handling and long operational life at elevated temperatures are required.

Key Features

• Capacitance and Voltage: 820 µF nominal capacitance at a rated voltage of 2.5 V with ±20% tolerance (measured at 120 Hz, 20°C).
• Ultra-low ESR: ESR specified at 6 mΩ at 100 kHz (20°C), minimizing voltage drop and power loss in high-frequency environments.
• High ripple-current capability: Rated ripple current of 6.1 A at 300 kHz and 610 mA at 120 Hz, supporting demanding power conditioning tasks.
• Low-profile radial can package: Compact φ8×8 mm case with 3.5 mm lead spacing and radial lead configuration for through-hole assembly.
• Wide temperature range and long life: Operating range −55°C to +105°C, with a load life rated at 5000 hours at 105°C.
• Polarized, lead-free assembly support: Polarized design and compatibility with lead-free flow soldering conditions; RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose power filtering: Low ESR and high ripple-current ratings make this capacitor suitable for smoothing and filtering on DC power rails.
• Compact power modules: Low-profile φ8×8 package and radial leads enable use where board space is constrained but high ripple handling is needed.
• High-frequency power circuits: ESR specified at 100 kHz and ripple coefficients across frequency support applications with significant high-frequency content.
• Elevated-temperature environments: Rated for operation to 105°C with a 5000-hour load life for extended reliability in hot operating conditions.

Unique Advantages

• Reduced power loss: 6 mΩ ESR at 100 kHz minimizes I²R losses and improves regulator efficiency.
• High ripple endurance: 6.1 A ripple capability at 300 kHz supports robust decoupling and bulk filtering in high-current switching supplies.
• Space-efficient form factor: φ8×8 mm low-profile can balances capacitance with a small footprint for compact designs.
• Long-term reliability at temperature: 5000-hour load life at 105°C offers predictable performance for sustained high-temperature operation.
• Manufacturing compatibility: Radial lead construction and lead-free flow soldering correspondence simplify assembly processes for through-hole production.
• Regulatory compliance: Conforms to RoHS requirements (2011/65/EU, (EU)2015/863) for restricted substances.
