RNU1C331MCN1

The RNU1C331MCN1 is a conductive polymer aluminum solid electrolytic capacitor in a radial lead can, designed for general-purpose electronics. It delivers low equivalent series resistance and high ripple current handling in a compact φ8×11.5 mm package, making it suitable for applications that require stable capacitance and robust power-performance in a wide temperature range.

Manufactured by Nichicon and available in mass production, this polarized capacitor combines a 330 µF capacitance at 16 V with a -55℃ to 105℃ operating range and a rated lifetime of 2000 hours at 105℃.

Key Features

• Capacitance & Voltage: 330 µF rated capacitance at 16 V with tolerance ±20% (at 120 Hz, 20℃).
• Low ESR: ESR specified at 8 mΩ measured at 20℃/100 kHz, supporting reduced loss and improved AC performance.
• High Ripple Current Capability: Rated ripple current of 610 mA at 120 Hz (low frequency) and 6.1 A at 300 kHz (high frequency), enabling effective handling of both low- and high-frequency ripple.
• Leakage Current: Leakage current specified at 1056 µA (after standard conditioning), suitable for many power applications requiring predictable leakage behavior.
• Endurance: Load life of 2000 hours at 105℃, with specified limits for capacitance change, tan δ, ESR and leakage after endurance testing.
• Robust Operating Range: Wide operating temperature range from -55℃ to 105℃ for use in varied environmental conditions.
• Radial Lead, Compact Package: φ8×11.5 mm can with 3.5 mm lead spacing (±0.5 mm), radial lead mounting for through-hole assemblies.
• Compliance & Packaging: RoHS compliant; available in bulk (no terminal forming) or bag packing.

Typical Applications

• General-purpose electronics: Suited for circuits requiring a 330 µF/16 V polarized capacitor for energy storage and decoupling in general-purpose designs.
• High-ripple power circuits: Appropriate where elevated ripple current capability is needed, leveraging 6.1 A (300 kHz) and 610 mA (120 Hz) ratings.
• Temperature-challenged environments: Use in systems operating across -55℃ to 105℃ where endurance of 2000 hours at 105℃ is required.

Unique Advantages

• Low-loss operation: 8 mΩ ESR at 100 kHz reduces AC losses and supports efficient high-frequency performance.
• High ripple tolerance: High rated ripple currents at both low and high frequencies enable reliable filtering and smoothing under dynamic loads.
• Compact radial form factor: φ8×11.5 mm can with 3.5 mm lead spacing provides a small footprint for through-hole assemblies without sacrificing capacitance.
• Wide temperature endurance: Rated for -55℃ to 105℃ operation with a defined 2000-hour life at 105℃ for predictable long-term behavior.
• predictable leakage and tolerance: Specified leakage current (1056 µA) and ±20% capacitance tolerance support reliable design margining.
• RoHS compliance and production availability: RoHS compliant and in mass production from Nichicon for supply chain continuity.
