RS80E471MDNASQ

The RS80E471MDNASQ from Nichicon is a conductive polymer aluminum solid electrolytic capacitor in a radial‑lead, low‑profile can. It delivers 470 µF at a 2.5 V rating with low ESR and high ripple current capability targeted for compact power and general‑purpose electronic designs.

Designed as part of the RS8 series, this mass‑production part combines low loss (tanδ 0.1 at 20°C/120 Hz), a wide operating temperature range of −55°C to 105°C, and a rated lifetime of 5000 hours at 105°C for reliable performance in space‑constrained power applications.

Key Features

• Capacitance and Voltage — 470 µF nominal capacitance with a rated voltage of 2.5 V and a standard tolerance of ±20%.
• Conductive Polymer Dielectric — Solid polymer construction provides stable performance and low loss (tanδ = 0.1 at 20°C, 120 Hz).
• Low ESR — ESR of 7 mΩ measured at 20°C/100 kHz, supporting efficient power delivery and reduced dissipation in high‑frequency circuits.
• High Ripple Current Capability — Rated ripple current of 560 mA at 120 Hz (low frequency) and 5.6 A at 300 kHz (high frequency), enabling effective smoothing in switching power stages.
• Robust Endurance — Load life rated to 5000 hours at 105°C under rated voltage conditions, with capacitance, tanδ and ESR meeting specified endurance criteria.
• Radial Lead Package — Polarized radial lead (φ6.3 × 8 mm can, 2.5 mm lead spacing) for through‑hole mounting and straightforward PCB integration.
• Leakage Current — Specified leakage current of 500 µA after two minutes at 20°C under rated voltage.
• Regulatory — RoHS compliant.

Typical Applications

• Power supply decoupling — Bulk and high‑frequency decoupling for compact DC‑DC converters and point‑of‑load modules where low ESR and high ripple handling are required.
• Smoothing in switching regulators — Energy smoothing and output filtering in switching power stages benefitting from the part’s low loss and high ripple current rating.
• General‑purpose electronics — Compact through‑hole designs that require polarized bulk capacitance with robust temperature and lifetime performance.

Unique Advantages

• Compact, low‑profile footprint — φ6.3 × 8 mm can dimensions enable high capacitance in tight mechanical envelopes.
• High ripple current without compromise — 5.6 A capability at high frequencies reduces thermal stress and improves filtering effectiveness in switching applications.
• Very low ESR — 7 mΩ at 100 kHz lowers I²R losses and supports efficient transient response.
• Extended operating range and life — −55°C to 105°C rating plus 5000 hours endurance at 105°C for consistent performance in demanding thermal environments.
• Ease of assembly — Radial lead form with 2.5 mm lead spacing simplifies through‑hole placement and soldering processes.
• Regulatory compliance — RoHS compliant for use in designs requiring hazardous‑substance restrictions.
