RR50G821MDN1

The RR50G821MDN1 is a conductive polymer aluminum solid electrolytic capacitor in a radial‑lead can, designed for general-purpose power applications. It combines an 820 µF capacitance at 4 V with an ultra-low ESR architecture to support high ripple currents and compact through‑hole mounting.

Manufactured by Nichicon as part of the RR5 series, this component targets designs that require high ripple handling, wide operating temperature range, and proven endurance in demanding thermal environments.

Key Features

• Capacitance & Voltage: 820 µF nominal capacitance with a rated voltage of 4 V and a capacitance tolerance of ±20% (120 Hz, 20°C).
• Ultra‑low ESR & High ripple current: ESR of 5 mΩ measured at 20°C/100 kHz supports a rated ripple current of 722 mA at 120 Hz and 7.22 A at 300 kHz (series rating 7220 mArms at 105°C/100 kHz).
• Thermal endurance: Rated operating temperature range from −55°C to +105°C with a load life of 2000 hours at 105°C.
• Leakage and dissipation: Leakage current specified at 820 µA (after 2 minutes at 20°C); tan δ (DF) specified at 0.15 (120 Hz, 20°C).
• Radial lead package: φ10 × 12.5 mm can with 5 mm lead spacing (±0.5 mm), radial lead mounting for through‑hole assembly and bulk/bag packaging options.
• Compliance & availability: RoHS compliant and listed as mass production.

Typical Applications

• General-purpose power smoothing: Bulk decoupling and smoothing in power rails where 820 µF and low ESR reduce voltage ripple and improve supply stability.
• High-frequency ripple filtering: Low ESR and high rated ripple current (7.22 A at high frequency) support filtering in high‑frequency power modules and switching converters.
• Through-hole board-level designs: Radial lead format with compact φ10×12.5 mm can and 5 mm lead spacing for easy placement in through‑hole assemblies and prototyping.

Unique Advantages

• Low ESR for efficient power handling: 5 mΩ ESR at 20°C/100 kHz enables high ripple current capability and reduces I²R losses in power stages.
• High ripple current rating: Rated for 722 mA at 120 Hz and 7.22 A at high frequency, suitable for demanding decoupling and filtering tasks.
• Robust thermal performance: −55°C to +105°C operating range with a 2000-hour life at 105°C for predictable long-term behavior under elevated temperatures.
• Compact radial package: φ10×12.5 mm can and 5 mm lead spacing provide a small footprint for through‑hole assemblies while maintaining high capacitance.
• Manufacturing-ready packaging: Available in bulk (no terminal forming) and bag packing for flexible assembly and inventory handling.
• RoHS compliant and production ready: Compliant to RoHS and listed as mass production in the Nichicon RR5 series.
