RNS1A471MDN1

The RNS1A471MDN1 is a conductive polymer aluminum solid electrolytic capacitor in a radial lead can. It delivers 470 µF nominal capacitance at a 10 V rated voltage and is intended for general-purpose electronics requiring low ESR and high ripple handling.

Designed and manufactured by Nichicon, this radial-leaded component offers a compact φ10×12.5 mm package with 5 mm lead spacing and a temperature rating from −55°C to +105°C, with an endurance rating of 2000 hours at 105°C.

Key Features

• Capacitance and Voltage — 470 µF nominal capacitance with ±20% tolerance at 120 Hz, rated for 10 V operation.
• Conductive Polymer Construction — Solid electrolytic design specified as conductive polymer aluminum for the RNS series.
• Low ESR — ESR specified at 10 mΩ measured at 20°C/100 kHz, supporting high-frequency performance.
• High Ripple Current Capability — Rated ripple current of 550 mA at 120 Hz and 5.5 A at 300 kHz, with frequency coefficients provided in the series datasheet.
• Leakage and Dissipation — Leakage current listed at 705 µA; tangent of loss angle (tan δ) 0.08 measured at 20°C, 120 Hz.
• Reliability and Lifetime — Endurance specified as 2000 hours at 105°C under rated voltage with defined limits for capacitance, tan δ and ESR change.
• Package and Mounting — Radial lead, can-style package φ10×12.5 mm, lead spacing 5 mm; supplied in bulk (no terminal forming) or bag packing.

Typical Applications

• General-purpose power electronics — Bulk capacitance and low ESR make it suitable for power-supply smoothing and ripple handling in general-purpose designs.
• High-frequency power rails — ESR specified at 100 kHz and high rated ripple current at 300 kHz support high-frequency decoupling needs.
• Industrial electronics — Wide operating temperature range (−55°C to +105°C) and 2000 h endurance at 105°C address thermal and lifetime requirements in industrial modules.

Unique Advantages

• Measured low ESR (10 mΩ at 100 kHz): Enables effective high-frequency performance as documented in the specifications.
• Broad ripple capability across frequency: Rated ripple current values of 550 mA at 120 Hz and 5.5 A at 300 kHz give predictable behavior across low and high frequencies.
• Solid polymer electrolyte: The conductive polymer aluminum solid construction delivers the specified leakage (705 µA) and tan δ (0.08 at 20°C, 120 Hz).
• Compact radial form factor: φ10×12.5 mm can with 5 mm lead spacing offers a space-efficient through-hole option for replacement or retrofit designs.
• Documented endurance: 2000 hours at 105°C under rated voltage with clear pass/fail criteria for capacitance, tan δ and ESR.
• Production availability: Listed as mass production with bulk or bag packing options for board-assembly flexibility.

Why Choose RNS1A471MDN1?

RNS1A471MDN1 combines conductive polymer aluminum solid construction, low ESR (10 mΩ at 100 kHz) and high ripple-current capability (up to 5.5 A at 300 kHz) in a compact radial-leaded can. These documented specifications make it a practical choice for engineers designing general-purpose power and high-frequency circuits that require reliable smoothing and ripple handling in a through-hole package.

Manufactured by Nichicon and offered in mass production with bulk or bag packing, this part suits projects and production runs where predictable electrical parameters, a defined 2000-hour endurance at 105°C, and a wide operating temperature range (−55°C to +105°C) are needed.
