RKS1V470MCNAHFGS

The RKS1V470MCNAHFGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor offering 47 µF capacitance at a 35 V rating. It combines low equivalent series resistance and high allowable ripple current in a compact radial SMD can (φ8 × 6.7 mm) for demanding board-level power applications.

Designed for high-frequency performance and elevated operating temperatures, this part targets designs that require low impedance, reliable long-term operation up to 125°C, and compatibility with lead-free reflow assembly processes.

Key Features

• Core Electrical — 47 µF capacitance with tolerance of -20% to +20% and rated voltage of 35 V for stable DC energy storage.
• Low Loss / Low ESR — ESR of 30 mΩ measured at 20°C/100 kHz and tanδ (DF) of 0.12 at 20°C/120 Hz, enabling low impedance at high frequency.
• High Ripple Handling — Low-frequency ripple current 160 mA (120 Hz) and high-frequency ripple current 1.6 A (300 kHz) for effective filtering in switching and high-frequency circuits.
• Leakage and Endurance — Leakage current specified at 100 µA and load life of 3000 hours at 125°C for long-term reliability under elevated temperature stress.
• Wide Temperature Range — Rated for operation from -55°C to +125°C to support high-temperature environments.
• Surface-Mount Assembly — Radial SMD can package (φ8 × 6.7 mm) with embossed carrier taping and moisture-proof packing; compatible with lead-free reflow soldering up to a 260°C peak per specified profiles.

Typical Applications

• Power supplies — Provides low-impedance filtering and ripple attenuation for switching regulators and DC–DC converter outputs.
• Power management modules — Suited for board-level bulk decoupling where high ripple current and stable capacitance at elevated temperatures are required.
• High-frequency power circuits — Optimized for smoothing and stability in circuits operating at hundreds of kilohertz due to low ESR at 100 kHz.

Unique Advantages

• Low ESR for tighter voltage stability: 30 mΩ at 100 kHz reduces voltage ripple and improves transient response in power rails.
• High ripple-current capability: 1.6 A at high frequency and 160 mA at low frequency allow this capacitor to handle demanding AC stress without excessive heating.
• High-temperature endurance: Rated for 3000 hours at 125°C, supporting reliable operation in thermally challenging applications.
• Reflow-compatible SMD package: Radial can design and lead-free reflow compatibility (260°C peak) simplify automated assembly for modern SMT lines.
• Compact footprint: φ8 × 6.7 mm size provides a high-capacitance option where board space is constrained.
