RNU1E470MCN1

The RNU1E470MCN1 is a Nichicon RNU series conductive polymer aluminum solid electrolytic capacitor in a radial lead can. It delivers 47 µF capacitance at a 25 V rating in a compact φ8×11.5 mm package with 3.5 mm lead spacing, designed for general-purpose electronic circuits.

Engineered for low impedance and high ripple capability, this radial-lead capacitor supports demanding operating conditions with a temperature range of −55°C to 105°C and a rated lifetime of 2000 hours at 105°C. It is RoHS compliant and available in bulk or bag packing for production use.

Key Features

• Capacitance & Voltage — 47 µF nominal capacitance with a rated voltage of 25 V and tolerance of −20% to +20% for predictable charge-storage behavior.
• Conductive Polymer Solid Electrolyte — Solid polymer aluminum chemistry for stable electrical characteristics and solid-electrolyte benefits within its specified life and temperature range.
• Low ESR — ESR of 24 mΩ measured at 20°C/100 kHz, supporting lower losses and better high-frequency performance in circuit applications.
• High Ripple Current Handling — Rated ripple currents of 360 mA at 120 Hz and 3.6 A at 300 kHz, enabling effective handling of both low- and high-frequency ripple loads.
• Temperature & Endurance — Operating temperature range −55°C to 105°C with an endurance rating of 2000 hours at 105°C, suitable for sustained operation under elevated temperature stress.
• Radial Through-Hole Package — φ8×11.5 mm radial can with 3.5 mm lead spacing (±0.5 mm), mounting type radial lead for through-hole PCB assembly workflows.
• Leakage & Loss — Specified leakage current of 587 µA (measured at 20°C after 2 minutes) and tanδ of 0.12 at 20°C/120 Hz for predictable loss characteristics.
• Compliance & Availability — RoHS compliant and offered in bulk or bag packing; listed as mass production status for supply continuity.

Typical Applications

• General-purpose electronic circuits — Suited where a 47 µF, 25 V radial polymer capacitor is required for standard board-level functions.
• Through-hole PCB assemblies — Radial lead format and 3.5 mm lead spacing accommodate conventional through-hole assembly and wave/flow soldering processes.
• Boards operating across wide temperatures — Useful in equipment that needs to maintain capacitor performance between −55°C and 105°C over extended periods.

Unique Advantages

• Lower dissipation losses: The 24 mΩ ESR at 100 kHz reduces power loss during high-frequency operation, improving efficiency in ripple-prone circuits.
• High ripple capability: Rated ripple currents up to 3.6 A at high frequency allow the part to handle significant AC stress without excessive heating within its rated life.
• Solid polymer stability: Conductive polymer electrolyte provides stable electrical behavior and predictable leakage and tanδ characteristics over the specified life.
• Compact radial form factor: φ8×11.5 mm can with standard lead spacing saves board space while supporting through-hole mounting practices.
• Production-ready supply: RoHS compliant and available in bulk/bag packing with mass-production status to support volume manufacturing requirements.
