RS81E820MCNASQ

The RS81E820MCNASQ is a conductive polymer aluminum solid electrolytic capacitor in a radial‑lead, low‑profile can (φ6.3 × 8 mm). It provides 82 µF capacitance at a 25 V rating with polarized radial leads and a compact footprint for space‑constrained assemblies.

Designed for general‑purpose power applications that require low ESR and high ripple handling in a small package, this Nichicon RS8 series part delivers measurable performance and long endurance across a wide temperature range.

Key Features

• Conductive polymer construction Solid electrolyte for stable electrical performance and low equivalent series resistance (ESR).
• Low ESR / High frequency performance ESR = 18 mΩ at 20°C / 100 kHz, supporting applications with demanding AC performance requirements.
• High ripple current capability Low‑frequency ripple current 350 mA (120 Hz) and high‑frequency ripple current 3.5 A (300 kHz) for effective smoothing under dynamic loads.
• Compact, low‑profile radial package Case size φ6.3 × 8 mm with 2.5 mm lead spacing (±0.5 mm), radial lead mounting for through‑hole assemblies.
• Robust operating range and endurance Operating temperature −55°C to +105°C with rated life tested to 5000 hours at 105°C.
• Electrical tolerance and characteristics 82 µF capacitance with ±20% tolerance, tan δ = 0.1 (20°C, 120 Hz), and leakage current specified at 615 µA.
• Packaging and production status Available in bulk (no terminal forming) or bag packing; part is in mass production and RoHS compliant.

Typical Applications

• Power supply decoupling Low ESR and high ripple current capability support local decoupling and smoothing in compact power circuits.
• Point‑of‑load filtering Compact φ6.3 × 8 mm package fits space‑restricted boards while providing stable filtering at high switching frequencies.
• General‑purpose electronic modules Suited for a wide range of general‑purpose applications that require long endurance across −55°C to +105°C.

Unique Advantages

• Measurable low ESR 18 mΩ (20°C/100 kHz) reduces voltage ripple and losses in high‑frequency circuits.
• High ripple handling Rated for up to 3.5 A at 300 kHz, enabling reliable smoothing in switching environments.
• Long life at elevated temperature 5000 hours endurance at 105°C supports extended field life in demanding thermal conditions.
• Small footprint, radial lead convenience φ6.3 × 8 mm can and 2.5 mm lead spacing simplify layout and mechanical assembly for through‑hole designs.
• RoHS compliant and production ready Mass production status and compliant materials ease integration into regulated manufacturing processes.
