RKS1D471MCNAJLGS

The RKS1D471MCNAJLGS is a surface-mount conductive polymer aluminum electrolytic capacitor from Nichicon's RKS series. It delivers 470 µF at 20 V in a compact φ10 × 12.4 mm can-style SMD package designed for general-purpose electronic applications.

Engineered for demanding thermal and ripple environments, this part offers low ESR, high allowable ripple current, and a rated operating range of −55 °C to 125 °C with a 3000‑hour endurance at 125 °C—making it suitable for applications that require stable bulk capacitance and robust lifetime performance.

Key Features

• Capacitance & Voltage — 470 µF nominal capacitance at a rated voltage of 20 V with a tolerance of −20% to +20% (measured at 120 Hz, 20 °C).
• Conductive Polymer Construction — Conductive polymer aluminum solid electrolytic design for stable electrical characteristics and long operational life.
• Low Loss (tan δ) — tanδ = 0.12 measured at 20 °C, 120 Hz for predictable AC behavior in filtering and decoupling roles.
• Low ESR — Equivalent series resistance of 20 mΩ at 20 °C, 100 kHz to minimize internal heating and voltage drop under ripple currents.
• High Ripple Current Capability — Low-frequency ripple current of 200 mA (120 Hz) and high-frequency ripple handling up to 2 A (300 kHz) for switching power supplies and regulator input filtering.
• Wide Temperature & Long Life — Rated for operation from −55 °C to 125 °C with a specified life/endurance of 3000 hours at 125 °C.
• Surface-Mount Package & Assembly Ready — Compact φ10 × 12.4 mm SMD radial can with embossed carrier taping and moisture-proof packing for automated placement and SMT assembly.
• RoHS Compliant — Meets RoHS requirements for environmentally restricted substances.

Typical Applications

• Switching Power Supplies — Bulk and output smoothing where high ripple currents and low ESR improve regulator stability and thermal performance.
• DC‑DC Converters — Input/output decoupling for point-of-load converters benefiting from compact high-capacitance in an SMD format.
• Industrial Control Electronics — General-purpose energy storage and filtering in systems operating across a wide temperature range, including elevated-temperature environments.

Unique Advantages

• High Capacitance in a Compact SMD Can — 470 µF in a φ10 × 12.4 mm footprint provides substantial bulk capacitance while conserving board area.
• Low ESR for Reduced Losses — 20 mΩ ESR at 100 kHz reduces dissipation under AC stress and supports higher ripple handling.
• Proven High‑Temperature Endurance — 3000‑hour life at 125 °C supports long-term reliability in thermally demanding applications.
• Wide Operating Temperature — −55 °C to 125 °C rating enables use across industrial and harsh-environment designs.
• Assembly-Friendly Packaging — Embossed carrier taping and moisture-proof packing streamline automated SMT production and storage.
• Regulatory Compliance — RoHS compliance simplifies environmental and regulatory management.
