RKS1E470MCNAHJGS

The RKS1E470MCNAHJGS from Nichicon is a surface-mount conductive polymer aluminum electrolytic capacitor rated at 47 µF and 25 V. Designed for general-purpose surface-mount applications, it combines low ESR and high allowable ripple current in a compact φ8 × 10 mm can-style SMD package.

This part is offered in embossed carrier tape with moisture-proof packing and is in mass production, making it suitable for automated assembly and volume production runs.

Key Features

• Capacitance & Voltage — 47 µF nominal capacitance with a tolerance of -20% to +20% at 20°C, rated for 25 V operation.
• Low Loss & Low ESR — Tangent of loss angle (tan δ) of 0.12 measured at 20°C, 120 Hz, and an ESR of 27 mΩ measured at 20°C/100 kHz for improved high-frequency performance.
• High Ripple Current Handling — Low-frequency ripple current 160 mA (120 Hz) and high-frequency ripple current 1.6 A (300 kHz) to support both bulk and high-frequency decoupling roles.
• Leakage & Polarization — Polarized electrolytic design with specified leakage current up to 100 µA after proper conditioning.
• Extended Temperature & Life — Rated for -55°C to +125°C with a load life endurance of 3000 hours at 125°C.
• Package & Assembly — Radial can SMD package (φ8 × 10 mm) supplied in embossed carrier tape with moisture-proof packing suitable for pick-and-place assembly.
• Regulatory — RoHS compliant.

Typical Applications

• General-purpose power circuits — Suitable where a 47 µF, 25 V SMD capacitor with low ESR and measurable high-frequency ripple capability is required for power stability.
• High-frequency decoupling — Utilized in circuits that benefit from low ESR (27 mΩ at 100 kHz) and a specified tan δ at 120 Hz for improved AC performance.
• Automated assembly production — Packaged in embossed carrier tape with moisture-proof packing for reliable placement in volume SMD production.

Unique Advantages

• Low ESR at high frequency: 27 mΩ (20°C/100 kHz) reduces voltage drop under high-frequency load and improves ripple attenuation.
• High allowable ripple current: 1.6 A (300 kHz) high-frequency rating plus 160 mA at 120 Hz supports both switching and low-frequency ripple conditions.
• Robust high-temperature endurance: 3000 hours at 125°C provides predictable lifetime performance in elevated-temperature environments.
• Compact SMD can package: φ8 × 10 mm can-style SMD footprint balances capacitance and board-space efficiency for space-constrained designs.
• Manufacturing-ready packaging: Embossed carrier tape and moisture-proof packing streamline pick-and-place and reflow assembly processes.
• RoHS compliance: Conforms to RoHS requirements for use in regulated regions and products.
