RR50J471MDN1

The RR50J471MDN1 is a conductive polymer aluminum solid electrolytic capacitor in a radial‑lead can, offering 470 µF capacitance at a 6.3 V rating. It is a polarized, general‑purpose component designed for circuits that require low ESR and high ripple‑current capability.

Built for robust thermal performance, this part supports an operating temperature range of −55°C to +105°C and a rated life of 2000 hours at 105°C, delivering reliable smoothing and decoupling in compact through‑hole designs.

Key Features

• Capacitance & Tolerance — 470 µF nominal capacitance with ±20% tolerance (specified at 120 Hz, 20°C in the series datasheet).
• Rated Voltage — 6.3 V DC rating for low‑voltage power circuits.
• Ultra‑low ESR — ESR specified at 5 mΩ (measured at 100 kHz, 20°C), minimizing loss and improving transient response.
• High ripple current capability — Rated ripple current of 663 mA at 120 Hz and 6.63 A at 300 kHz, with frequency coefficients provided for design across a wide frequency range.
• Long load life — Endurance: 2000 hours at 105°C under rated voltage with limits on capacitance change, tan δ, ESR and leakage current per the series specification.
• Compact radial can package — φ8×11.5 mm size (L × D), radial lead mounting with 3.5 mm lead spacing for through‑hole PCB layouts.
• Thermal and environmental compliance — Operating range −55°C to +105°C and RoHS compliant; radial lead type conforms to lead‑free flow soldering conditions per the series datasheet.

Typical Applications

• General‑purpose electronics — Provides bulk capacitance and low ESR for a wide range of consumer and industrial circuits that list "General Purpose" in application requirements.
• Power filtering and decoupling — High ripple current ratings and low ESR make it suitable for smoothing and decoupling at both low and high frequencies as indicated by the series frequency‑coefficient data.
• Through‑hole PCB designs — Radial lead package and 3.5 mm lead spacing allow straightforward integration into through‑hole layouts where compact, polarized capacitance is required.

Unique Advantages

• Low ESR for improved efficiency: 5 mΩ ESR at 100 kHz reduces I²R loss and supports tighter voltage regulation under load.
• High ripple handling across frequency: Rated ripple current values (663 mA at 120 Hz and 6.63 A at 300 kHz) and frequency coefficients enable designers to size capacitors for both low‑ and high‑frequency ripple conditions.
• Compact, space‑efficient package: φ8×11.5 mm can size with 3.5 mm lead spacing fits constrained through‑hole areas without sacrificing capacitance.
• Long endurance at elevated temperature: 2000 hours at 105°C validates performance stability for thermal stress conditions specified in the datasheet.
• RoHS compliant and lead‑free solder compatible: Meets RoHS requirements and is specified for lead‑free flow soldering conditions per the series documentation.
