RNU1E331MDNASQ

The RNU1E331MDNASQ is a conductive polymer aluminum solid electrolytic capacitor in a radial-lead can, offering 330 µF capacitance at a 25 V rating. Designed for general-purpose electronic applications, it delivers a combination of high capacitance, low ESR and elevated ripple-current capability.

Key operational attributes include an ESR of 14 mΩ (20°C/100 kHz), rated ripple current up to 5.0 A at 300 kHz, and an endurance rating of 5000 hours at 105°C. The component is RoHS compliant and available in bulk or bag packing for production use.

Key Features

• Conductive polymer dielectric Solid electrolyte construction for stable capacitance and reduced ESR compared to conventional electrolytics.
• Low ESR and high-frequency performance ESR = 14 mΩ at 20°C/100 kHz, supporting high-frequency decoupling and fast transient response.
• High ripple-current capability Rated ripple current: 500 mA at 120 Hz and 5.0 A at 300 kHz, enabling effective smoothing under both low- and high-frequency loading.
• Robust thermal endurance Rated lifetime of 5000 hours at 105°C with operating temperature range of –55°C to +105°C.
• Radial lead package Compact φ10 × 12.5 mm can with 5.0 mm lead spacing (±0.5 mm) for through-hole assemblies and hand or wave-solder processes.
• Polarized, general-purpose use Polarized capacitor suitable for a wide range of general-purpose electronic circuits.
• Compliance and availability RoHS compliant and in mass production; supplied in bulk (no terminal forming) or bag packing.

Typical Applications

• Power rail decoupling and smoothing – Low ESR and high ripple-current capability make this part suitable for stabilizing DC power rails and absorbing transient currents.
• Switching power supplies – High-frequency ripple performance (ESR specified at 100 kHz) supports use near switching nodes and output stages.
• Industrial and consumer electronics – Wide operating temperature range (–55°C to +105°C) and extended life (5000 h at 105°C) suit sustained operation in varied environments.

Unique Advantages

• Measured low ESR – 14 mΩ at 20°C/100 kHz provides leeway for high-current and high-frequency applications without relying on multiple parallel devices.
• Broad ripple capability – Specified ripple current values at both low and high frequencies (500 mA at 120 Hz; 5.0 A at 300 kHz) let designers address mixed-frequency noise and load conditions.
• Long thermal life – 5000-hour endurance at 105°C supports designs requiring sustained reliability at elevated temperatures.
• Compact radial form factor – φ10 × 12.5 mm can and 5 mm lead spacing provide a small footprint for through-hole implementations while retaining substantial capacitance.
• Production-ready supply – Mass-production status and RoHS compliance simplify procurement and regulatory handling for volume designs.
