RF80E471MDN1

The RF80E471MDN1 from Nichicon is a conductive polymer aluminum solid electrolytic capacitor in a radial-lead, low-profile φ5 can. Designed for general-purpose power applications, it combines low ESR/ESL and high ripple-current capability in a compact 5×8 mm package.

This part is optimized for compact power decoupling and local energy storage where elevated temperature endurance and low impedance at high frequency are required. Key value propositions include very low ESR (7 mΩ at 20°C/100 kHz), high-frequency ripple handling (up to 4.2 A), and a rated life of 2000 hours at 105°C.

Key Features

• Construction  Conductive polymer aluminum solid electrolytic design for stable electrical performance and low impedance.
• Capacitance & Voltage  470 µF nominal capacitance with a rated voltage of 2.5 V and capacitance tolerance of −20% to +20% (120 Hz, 20°C).
• Low ESR / Low ESL  ESR of 7 mΩ (20°C/100 kHz) and typical ESL ~1.5 nH, delivering low impedance at high frequency for improved transient response.
• High Ripple Current  Low-frequency ripple current 420 mA (120 Hz) and high-frequency capability up to 4.2 A (specified condition), supporting converters and point-of-load applications.
• Thermal Endurance  Rated for operation from −55°C to +105°C with a load life of 2000 hours at 105°C.
• Size & Mounting  Radial lead package, case φ5 × 8 mm, lead spacing 2.0 mm (±0.5 mm) for compact PCB placement and through-hole assembly.
• Leakage & Loss  Leakage current specified at 500 µA (after 2 minutes at 25°C) and tanδ ≤ 0.10 at 120 Hz, 20°C.
• Compliance & Packaging  RoHS compliant; available in bulk (no terminal forming) or bag packing.

Typical Applications

• Point-of-load decoupling  Low ESR and high ripple capability make this capacitor suitable for smoothing and stabilizing outputs of DC‑DC converters in compact power modules.
• Power-supply filtering  High-frequency ripple handling and low impedance at 100 kHz+ help reduce voltage ripple and improve regulator stability.
• Embedded and portable electronics  Small footprint (φ5×8 mm) and wide temperature range (−55°C to +105°C) support tight spaces and harsh-environment operation.

Unique Advantages

• Compact low-profile package: Enables high-density board layouts while providing 470 µF capacitance in a φ5×8 mm can.
• Low impedance at high frequency: 7 mΩ ESR and low ESL deliver effective decoupling for fast transient loads and switching power stages.
• High ripple tolerance: Rated ripple current up to 4.2 A at high frequency supports demanding converter and regulator designs.
• Long elevated-temperature life: 2000 hours at 105°C gives predictable endurance for designs exposed to sustained thermal stress.
• Through-hole robustness: Radial lead format and defined lead spacing simplify assembly and mechanical stability for power electronics.
• RoHS compliant: Meets environmental requirements for lead-free systems and regulatory compliance.
