RNE0E821MDNASQ

The RNE0E821MDNASQ is a conductive polymer aluminum solid electrolytic capacitor in a radial lead can, rated 820 µF at 2.5 V. Designed for general-purpose applications, it combines high capacitance with low ESR and high ripple-current capability for compact power and decoupling applications.

Key attributes include a compact φ8×6 mm case, a wide operating temperature range from −55 °C to 105 °C, and an endurance rating of 5000 hours at 105 °C, delivering stable performance in space-constrained designs that demand high-frequency ripple handling and low loss.

Key Features

• Capacitance & Voltage — 820 µF nominal capacitance with a rated voltage of 2.5 V and tolerance of −20% to +20% (at 120 Hz, 20 °C).
• Low Equivalent Series Resistance (ESR) — ESR specified at 8 mΩ (20 °C, 100 kHz), reducing dissipation and improving efficiency in high-current paths.
• High Ripple Current Capability — Rated ripple currents of 490 mA at 120 Hz and 4.9 A at 300 kHz support both low- and high-frequency filtering requirements.
• Thermal and Lifetime Performance — Operating temperature from −55 °C to 105 °C with 5000 hours endurance at 105 °C, suitable for sustained elevated-temperature operation.
• Low Leakage and Losses — Leakage current specified at 500 µA (after 2 minutes at 20 °C) and tanδ of 0.1 (20 °C, 120 Hz), enabling predictable DC performance.
• Compact Radial Package — φ8×6 mm case with 3.5 mm lead spacing (±0.5 mm) in a radial lead, can-style package for through-hole layouts; available in bulk/bag packing.
• Regulatory — RoHS compliant and in mass production.

Typical Applications

• Power-supply decoupling and smoothing — Low ESR and high ripple-current ratings make this capacitor suitable for output filtering in compact DC‑DC converters and power modules.
• High-frequency filtering — Robust performance at 100–300 kHz ripple conditions supports high-frequency switching applications where low loss and stability are needed.
• Compact consumer and industrial electronics — Small φ8×6 mm radial package and 3.5 mm lead spacing enable use in space-constrained through-hole designs.

Unique Advantages

• High ripple tolerance: Up to 4.9 A at 300 kHz lets designers handle substantial AC stress without oversized capacitors.
• Reduced power loss: 8 mΩ ESR at 100 kHz minimizes I²R losses and heat generation in high-current circuits.
• Compact footprint: φ8×6 mm can and short height support dense board layouts and small-form-factor assemblies.
• Broad temperature and long-life rating: −55 °C to 105 °C operating range and 5000 hours at 105 °C provide durability for sustained elevated-temperature use.
• Predictable leakage and dielectric behavior: 500 µA leakage (after 2 minutes) and tanδ = 0.1 (20 °C, 120 Hz) aid predictable system-level behavior and margin calculations.
• Production-ready availability: RoHS-compliant and in mass production for reliable supply in volume deployments.
