RR50J821MDN1

The RR50J821MDN1 is a conductive polymer aluminum solid electrolytic capacitor in a radial-lead can, offering 820 µF capacitance at a 6.3 V rating. It is part of Nichicon's RR5 series and is designed for general-purpose electronic applications that require low equivalent series resistance and high ripple-current capability.

Key value propositions include ultra-low ESR, high ripple current handling, and a robust operating temperature range with a 2000-hour endurance rating at 105°C, making it suitable where long-term stability under elevated temperature and load is required.

Key Features

• Capacitance and Voltage — 820 µF nominal capacitance with a rated voltage of 6.3 V and a tolerance of ±20% (120 Hz, 20°C).
• Ultra-low ESR — ESR specified at 5 mΩ measured at 20°C/100 kHz, supporting low-loss operation and improved power delivery.
• High ripple-current capability — Rated ripple current of 722 mA at 120 Hz and 7.22 A (7220 mA) at high frequency (300 kHz), enabling effective handling of both low- and high-frequency ripple.
• Low dielectric loss — tan δ (DF) of 0.15 measured at 20°C/120 Hz for stable performance in typical operating conditions.
• Thermal and endurance performance — Operating temperature range of −55°C to +105°C with a load life (endurance) of 2000 hours at 105°C.
• Package and mounting — Radial lead mounting in a φ10 × 12.5 mm can with 5 mm lead spacing (±0.5 mm), available in bulk (no terminal forming) or bag packing.
• Leakage current — Specified leakage current of 1291 µA (after 2 minutes at 20°C with rated voltage applied).
• RoHS compliant — Conforms to the RoHS directive as indicated in product data.

Typical Applications

• General-purpose electronic equipment — Suited for circuits that require high capacitance with low ESR and strong ripple-current handling for power smoothing and decoupling.
• Board-level radial-lead installations — Appropriate where a radial can (φ10 × 12.5 mm) with 5 mm lead spacing is required for through-hole mounting and robust mechanical connection.
• High-temperature environments — Applicable where operation up to 105°C and a 2000-hour endurance at that temperature are necessary for reliable long-term performance.

Unique Advantages

• Low-loss power handling: 5 mΩ ESR at 100 kHz reduces conduction losses and supports efficient power delivery in high-current circuits.
• High ripple-current capability: 7.22 A at 300 kHz and 722 mA at 120 Hz provide headroom for both switching and lower-frequency ripple scenarios.
• Robust thermal endurance: Rated for 2000 hours at 105°C, offering predictable aging and performance in elevated-temperature applications.
• Compact radial package: φ10 × 12.5 mm can and 5 mm lead spacing deliver a space-efficient through-hole option for board-level power components.
• Measured dielectric stability: tan δ of 0.15 at 20°C/120 Hz supports consistent loss characteristics under typical measurement conditions.
• Regulatory compliance: RoHS conformity supports use in applications requiring lead-free materials compliance.
