RNS0G821MDN1

The RNS0G821MDN1 is a conductive polymer aluminum solid electrolytic capacitor in a radial-leaded can, rated at 820 µF and 4 V. It is designed for general purpose electronic applications requiring low ESR, high ripple handling, and extended temperature performance.

With a compact φ10×12.5 mm package and 5 mm lead spacing, this mass-production part delivers low-loss operation (tanδ 0.08 at 20℃/120 Hz) and robust ripple-current capability for board-level power and decoupling tasks.

Key Features

• Capacitance & Tolerance — 820 µF nominal with tolerance of −20% to +20% (measured at 120 Hz, 20℃).
• Rated Voltage — 4 V (surge 4.6 V), suitable for low-voltage power rails.
• Low ESR — ESR of 10 mΩ measured at 20℃/100 kHz for improved efficiency at high frequencies.
• High Ripple Current Capability — Low-frequency ripple current 550 mA at 120 Hz and high-frequency ripple current 5.5 A at 300 kHz, supported by the frequency coefficient characteristics in the datasheet.
• Loss Angle — tanδ 0.08 (20℃/120 Hz) for low dissipation in application-relevant conditions.
• Leakage Current — 492 µA (specified after 2 minutes at 25℃), enabling predictable standby behavior.
• Endurance & Temperature Range — Rated life 2000 hours at 105℃; operating range −55℃ to 105℃ for a wide array of environments.
• Package & Mounting — Radial lead, can package φ10×12.5 mm with 5 mm lead spacing; available in bulk (no terminal forming) or bag packing.

Typical Applications

• General Purpose Electronics — Suited to circuits requiring conductive polymer electrolytic capacitors for general-purpose smoothing and energy storage where stable capacitance and low ESR are needed.
• High-Frequency Circuits — Low ESR at 100 kHz and documented ripple-current coefficients support use in applications operating at elevated switching frequencies.
• Power Supply Filtering — Combination of 820 µF capacitance, low tanδ, and high ripple-current capability helps manage ripple and transient currents on low-voltage rails.

Unique Advantages

• Conductive Polymer Electrolyte: Offers stable electrical characteristics and low internal resistance compared with many traditional electrolytes.
• Low ESR (10 mΩ at 100 kHz): Minimizes voltage drop and power loss under high-frequency operation, improving overall power-stage efficiency.
• High Ripple-Current Handling: Rated for 550 mA at 120 Hz and 5.5 A at 300 kHz, enabling reliable performance in both low- and high-frequency ripple environments.
• Wide Operating Temperature: −55℃ to 105℃ rating supports demanding thermal environments while maintaining specified performance.
• Endurance Rated: 2000 hours at 105℃ provides predictable lifetime behavior for thermal stress conditions.
• Compact Radial Can: φ10×12.5 mm package with 5 mm lead spacing balances board space efficiency with easy through-hole mounting and handling.
