RNE0E821MCNASQ

The RNE0E821MCNASQ is a conductive polymer aluminum solid electrolytic capacitor in a radial-lead can, optimized for general-purpose electronic designs. It delivers 820 µF at 2.5 V with very low ESR and high ripple-current capability in a compact φ8×6 mm package.

Engineered for robust performance across a wide temperature range, this part targets applications that require high capacitance density, low losses, and extended endurance up to 5000 hours at 105°C.

Key Features

• Capacitance and Voltage: 820 µF rated capacitance at 2.5 V with ±20% tolerance, providing substantial bulk capacitance in a small radial package.
• Low ESR / High-Frequency Performance: ESR of 8 mΩ measured at 20°C / 100 kHz and tanδ 0.1 (20°C, 120 Hz), supporting high-frequency decoupling and low-loss operation.
• High Ripple Current Capability: Rated ripple current up to 4.9 A at 100 kHz (4900 mA) and 490 mA at 120 Hz, enabling reliable operation under dynamic load conditions.
• Endurance and Temperature Range: Life rating of 5000 hours at 105°C and an operating temperature range of −55°C to +105°C for long-term stability in elevated-temperature environments.
• Package and Mounting: Radial-lead can, size φ8×6 mm (L: 6 × D: 8 mm) with 3.5 mm lead spacing (±0.5 mm tolerance); available in bulk (no terminal forming) or bag packing.
• Leakage and Reliability: Leakage current specified at 500 µA (after 2 minutes at 20°C) and designed to maintain capacitance, tanδ and ESR within specified limits through endurance testing.
• RoHS Compliant: Product is compliant with RoHS requirements.

Typical Applications

• General-purpose electronics — Suited for circuits requiring compact bulk capacitance and low ESR in a radial-lead form factor.
• Power modules and rails — Supports high ripple currents and low-loss filtering where long endurance at elevated temperatures is required.
• Embedded and portable devices — Provides high capacitance in a small footprint for energy storage and transient suppression in space-constrained designs.

Unique Advantages

• High capacitance density: 820 µF at 2.5 V in a φ8×6 mm can reduces board area for bulk storage compared with larger packages.
• Low ESR at high frequency: 8 mΩ (20°C/100 kHz) minimizes losses and heat generation under high-frequency switching conditions.
• Strong ripple-current handling: 4.9 A rated ripple at 100 kHz accommodates demanding dynamic loads without excessive temperature rise.
• Extended high-temperature life: 5000-hour endurance at 105°C provides predictable long-term behavior for designs exposed to elevated temperatures.
• Radial-lead convenience: Standard lead spacing and can packaging simplify through-hole assembly and replacement in hand-assembled or wave-soldered workflows.
