RNU1C471MDN1

The RNU1C471MDN1 is a conductive polymer aluminum solid electrolytic capacitor in a radial lead can, offering 470 µF capacitance at a 16 V rating. Designed for general‑purpose electronic applications, it combines high capacitance density with low equivalent series resistance and high ripple current capability.

This part targets designs that require robust ripple handling and thermal endurance, delivering a 2000‑hour rated life at 105°C and RoHS compliance for modern production environments.

Key Features

• Capacitance & Voltage — 470 µF capacitance with a rated voltage of 16 V and tolerance of −20% to +20%.
• Low ESR — ESR specified as 10 mΩ at 20°C/100 kHz, supporting low-loss operation at high frequencies.
• High Ripple Current — Rated ripple current of 610 mA at 120 Hz and 6.1 A at 300 kHz, with frequency coefficients provided in the series datasheet for frequency scaling.
• Dielectric Loss — tanδ (DF) of 0.08 measured at 20°C, 120 Hz, enabling predictable AC behavior.
• Thermal Endurance — Rated life/endurance of 2000 hours at 105°C, with operating temperature range from −55°C to +105°C.
• Leakage Current — Specified leakage current of 1504 µA (after 2 minutes at 20°C under rated voltage conditions).
• Radial Lead Package — Compact φ10 × 12.5 mm can with 5 mm lead spacing (±0.5 mm), available in bulk or bag packing and in mass production status.
• Regulatory — RoHS compliant.

Typical Applications

• General-purpose electronic circuits — Applicable where a 470 µF, 16 V radial lead capacitor with low ESR and high ripple capability is required.
• Power handling modules — Suited to designs that need high ripple current capacity and low AC loss at elevated frequencies and temperatures.
• Industrial and consumer assemblies — Can be used in assemblies that demand long life at up to 105°C and reliable radial lead mounting.

Unique Advantages

• High capacitance in a compact radial can — 470 µF in a φ10 × 12.5 mm package conserves board area while providing substantial energy storage.
• Low-loss operation — 10 mΩ ESR at 100 kHz and tanδ of 0.08 reduce power dissipation and thermal stress under AC loading.
• Strong ripple-handling capability — Rated ripple currents of 610 mA (120 Hz) and 6.1 A (300 kHz) accommodate both low- and high-frequency AC environments.
• Extended high-temperature life — 2000 hours at 105°C supports designs requiring prolonged thermal reliability.
• Radial lead convenience — 5 mm lead spacing and standard radial can format simplify through-hole assembly and replacement workflows.
• Regulatory readiness — RoHS compliance for inclusion in modern, regulated product builds.
