RNU1E330MCN1

The RNU1E330MCN1 is a conductive polymer aluminum solid electrolytic capacitor in a radial-lead can package. It delivers 33 µF at 25 V with low ESR and high ripple-current capability, aimed at general-purpose electronic designs that require compact, high-performance power filtering.

Manufactured by Nichicon and supplied in bulk or bag packing, this radial-lead device is designed for applications that demand stable performance across a wide temperature range (−55 °C to 105 °C) and extended endurance (2,000 hours at 105 °C).

Key Features

• Capacitance & Voltage: 33 µF rated capacitance at 25 V with a tolerance of −20% to +20%, suitable for a broad range of general-purpose decoupling and filtering roles.
• Low ESR & High-Frequency Performance: ESR of 24 mΩ measured at 20 °C / 100 kHz, supporting high-frequency applications and reducing power loss.
• High Ripple Current Capability: Rated ripple current of 360 mA at 120 Hz and 3.6 A at 300 kHz, enabling reliable ripple handling in both low- and high-frequency circuits.
• Loss Tangent (tan δ): tanδ of 0.12 (measured at 20 °C, 120 Hz), providing predictable dielectric loss characteristics for AC and switching environments.
• Reliability & Endurance: Load life of 2,000 hours at 105 °C under rated voltage conditions, with leakage current specified at 412 µA after standard conditioning.
• Compact Radial Package: Can size φ8 × 11.5 mm (L: 1.15 cm × D: 0.8 cm) with 3.5 mm lead spacing (±0.5 mm), ideal for through-hole assemblies where board space is constrained.
• Wide Operating Temperature: Specified for −55 °C to 105 °C operation, supporting a broad set of environmental conditions.
• Compliance & Availability: RoHS compliant and in mass production.

Typical Applications

• Power supply decoupling: Low ESR and substantial ripple-current ratings make this capacitor suitable for bulk and local decoupling on power rails.
• Switching power supplies / DC–DC converters: High-frequency ripple capability and 100 kHz ESR specification support use near switching nodes and output stages.
• General-purpose electronics: Designed for a wide range of general-purpose circuit needs where compact, reliable electrolytic capacitance is required.

Unique Advantages

• Lower conduction losses: 24 mΩ ESR at 100 kHz reduces I²R losses and heat generation in high-current or high-frequency circuits.
• High ripple endurance: Rated ripple currents (360 mA at 120 Hz and 3.6 A at 300 kHz) enable robust performance in both low- and high-frequency ripple environments.
• 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 endurance.
• Wide temperature range and defined life: −55 °C to 105 °C rating and 2,000-hour endurance at 105 °C provide predictable long-term behavior in demanding thermal conditions.
• Measured dielectric and leakage characteristics: Specified tanδ (0.12 at 20 °C/120 Hz) and leakage current (412 µA) allow designers to model AC losses and standby currents accurately.
• RoHS compliant and production-ready: Environmentally compliant and available in mass production for consistent supply and deployment.
