RNU1J330MDN1

The RNU1J330MDN1 is a radial-lead conductive polymer aluminum solid electrolytic capacitor from Nichicon's RNU series. It delivers 33 µF capacitance at a 63 V rating in a compact φ8×11.5 mm can package designed for general-purpose power filtering and decoupling in electronic systems.

Built for applications that require low ESR and high ripple handling in a small footprint, this part combines a wide operating temperature range (−55°C to +105°C) with a 2000 hour endurance at 105°C to support reliable operation in demanding environments.

Key Features

• Capacitance & Voltage — 33 µF nominal capacitance with a 63 V rated voltage and ±20% tolerance for predictable energy storage and decoupling performance.
• Low ESR and High-Frequency Performance — ESR of 26 mΩ measured at 20°C/100 kHz supports low-loss performance at switching frequencies; tan δ = 0.12 at 20°C/120 Hz indicates stable loss characteristics.
• High Ripple Current Capability — Rated ripple current of 230 mA at 120 Hz (low frequency) and 2.3 A at 300 kHz (high frequency) enables effective filtering in both mains-frequency and switching-regulator environments.
• Temperature and Endurance — Operating range −55°C to +105°C with a specified life/endurance of 2000 hours at 105°C (at rated voltage), suitable for sustained thermal stress conditions.
• Leakage and Reliability — Leakage current specified at 415 µA; datasheet measurement convention applies (measured at 20°C after voltage application per datasheet conditions).
• Radial Can Package — φ8×11.5 mm can, radial lead mounting with 3.5 mm lead spacing (±0.5 mm tolerance); available in bulk (no terminal forming) or bag packing for production flexibility.
• RoHS Compliant — Meets RoHS directive requirements as specified in the product data.

Typical Applications

• Switching Regulators — Low ESR and high ripple current rating make it suitable for output filtering and smoothing in DC–DC converters and switching power supplies.
• Power Supply Input Filtering — Compact φ8×11.5 mm package provides bulk capacitance and ripple handling for input filtering on power rails where board space is constrained.
• Industrial Electronics — Wide temperature range (−55°C to +105°C) and 2000 hour endurance at 105°C support stable performance in industrial control and instrumentation power circuits.

Unique Advantages

• Measurable Low-Loss Performance: ESR 26 mΩ at 20°C/100 kHz and tan δ = 0.12 at 20°C/120 Hz enable predictable AC behavior for high-frequency designs.
• High Ripple Handling in a Small Can: 2.3 A ripple at 300 kHz (and 230 mA at 120 Hz) delivers robust filtering where switching noise is present without requiring a larger package.
• Temperature and Endurance Balance: −55°C to +105°C operation with 2000 h life at 105°C offers a balance between compact size and long-term thermal reliability.
• Radial Lead Convenience: Standard radial-lead can with 3.5 mm lead spacing simplifies through-hole assembly and replacement in legacy and mixed-technology designs.
• Production-Ready Packaging: Available in bulk (no terminal forming) or bag packing to match assembly and inventory workflows.
• Regulatory Compliance: RoHS compliance supports use in designs targeting regional environmental requirements.
