RNU0G122MCN1

The RNU0G122MCN1 is a conductive-polymer aluminum solid electrolytic capacitor in a radial-lead can, offering 1.2 mF capacitance at a 4 V rating. Designed for general-purpose applications, it combines high capacitance density with low ESR and high ripple-current capability for demanding power-filtering and energy-storage roles.

Key value propositions include low equivalent series resistance (7 mΩ at 20°C/100 kHz), substantial high-frequency ripple handling (5.7 A at 300 kHz), and a broad operating temperature range from −55°C to 105°C with a specified endurance of 2000 hours at 105°C.

Key Features

• Capacitance & Voltage — 1200 µF nominal capacitance with a 4 V rated voltage and tolerance of −20% to +20%.
• Low ESR — Equivalent Series Resistance of 7 mΩ measured at 20°C/100 kHz, supporting efficient power delivery and reduced loss at high frequencies.
• High Ripple Current — Rated ripple current 570 mA at 120 Hz and 5.7 A at 300 kHz, with frequency coefficients per the RNU series specifications for robust AC performance.
• Loss Angle (tanδ) — tanδ of 0.08 (measured at 20°C, 120 Hz) for predictable dissipation characteristics in AC conditions.
• Reliability / Life — Load life specified at 2000 hours at 105°C under rated voltage; capacitance, tanδ and ESR limits are defined per the RNU series endurance criteria.
• Package & Mounting — Radial lead can: size φ8 × 11.5 mm, lead spacing 3.5 mm (±0.5 mm); available in bulk (no terminal forming) or bag packing for flexible assembly handling.
• Leakage Current — Specified leakage current of 960 µA (measured at 20°C after 2 minutes at rated voltage).
• Compliance — RoHS–compliant construction.

Typical Applications

• General-purpose power filtering — Use where low ESR and significant ripple-current capability are required for smoothing and decoupling in power circuits.
• High-frequency power stages — Suited to circuits that demand stable high-frequency ripple handling, leveraging the 5.7 A rating at 300 kHz and ESR specified at 100 kHz.
• Energy storage and hold-up — Provides compact bulk capacitance at low voltage for local energy buffering in compact designs.

Unique Advantages

• High capacitance in a compact radial can — 1200 µF in an φ8 × 11.5 mm package supports size-constrained layouts without sacrificing capacitance.
• Excellent AC performance — Low ESR (7 mΩ) and specified high-frequency ripple current minimize losses and improve thermal performance under alternating currents.
• Predictable behavior over temperature — Rated for −55°C to 105°C with defined endurance at 105°C, enabling consistent performance in a wide range of operating environments.
• Ready for production — Mass-production status and standard packaging options (bulk/bag) simplify procurement and assembly planning.
• Polymer electrolyte benefits — Conductive polymer construction yields stabilized ESR and ripple characteristics per the RNU series specifications.
