RS80J471MCNASQ

The RS80J471MCNASQ is a Nichicon RS8 series conductive polymer aluminum solid electrolytic capacitor designed for compact, high-ripple power applications. It is a radial-lead, low-profile (φ6.3) polarized capacitor providing 470 µF at 6.3 V with low ESR and ESL characteristics.

Engineered for demanding power-filtering roles, this part combines low equivalent series resistance (8 mΩ at 100 kHz) and high allowable ripple currents to support compact power modules, DC–DC converter outputs, and other general-purpose power electronics operating across –55 °C to +105 °C. It is lead-free flow soldering compatible and RoHS compliant.

Key Features

• Capacitance & Voltage — 470 µF rated capacitance at 6.3 V, with a capacitance tolerance of ±20% (at 120 Hz, 20 °C).
• Low ESR / ESL — ESR specified at 8 mΩ (100 kHz, 20 °C), enabling low-loss operation at switching frequencies.
• High Ripple Current — Supports 500 mA at 120 Hz and up to 5 A at 300 kHz, with frequency ripple coefficients defined in the datasheet for design scaling.
• Robust Temperature & Lifetime — Rated for operation from –55 °C to +105 °C with a load life of 5000 hours at 105 °C.
• Compact Low-Profile Package — 6.3 mm diameter × 8 mm length (φ6.3×8 mm) with 2.5 mm lead spacing, ideal for space-constrained assemblies.
• Radial Lead, Lead-Free Soldering — Radial lead configuration compatible with lead-free flow soldering conditions and polarized mounting.
• Regulatory — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• DC–DC Converter Output Filtering — Low ESR and high ripple capability make this capacitor suitable for smoothing and stabilizing outputs in compact converter modules.
• Power Supply Bulk/Decoupling — 470 µF capacitance combined with low ESR helps reduce voltage ripple and improve transient response in general-purpose power supplies.
• High-Frequency Power Circuits — ESR specified at 100 kHz and high-frequency ripple ratings (up to 300 kHz) support applications with switching regulators and high-frequency noise reduction.
• Compact Consumer and Industrial Electronics — Low-profile φ6.3 package fits space-limited boards where robust thermal and ripple performance are required.

Unique Advantages

• Lower Power Losses: 8 mΩ ESR at 100 kHz reduces I²R losses in high-current switching applications, improving efficiency and thermal performance.
• High-Frequency Capability: Rated ripple current of 5 A at 300 kHz and published frequency coefficients allow predictable performance scaling across switching frequencies.
• Space-Saving Form Factor: φ6.3×8 mm low-profile can fit in compact designs without sacrificing capacitance or ripple handling.
• Thermal Endurance: 5000 hours load life at 105 °C supports designs requiring long-term stability under elevated operating temperatures.
• Assembly-Friendly: Radial-lead construction with lead-free flow soldering compatibility simplifies through-hole assembly processes.
• Regulatory Compliance: RoHS conformity supports deployment in regions and products requiring restricted-substances compliance.
