RKS1E470MCNAHFGS

The RKS1E470MCNAHFGS is a surface-mount conductive-polymer aluminum solid electrolytic capacitor with a rated capacitance of 47 µF and a rated voltage of 25 V. It combines low equivalent series resistance and high allowable ripple current in a compact φ8 × 6.7 mm SMD can to support high-frequency power and decoupling applications.

Designed for robust thermal and endurance performance, this device is specified for operation from -55 °C to +125 °C and a rated load life of 3000 hours at 125 °C. Packaging is optimized for volume assembly with embossed carrier taping and moisture-proof packing; the part is in mass production.

Key Features

• Capacitance & Tolerance — 47 µF nominal capacitance with ±20% tolerance at 20 °C, 120 Hz.
• Rated Voltage — 25 V DC rating suitable for common low-voltage power rails.
• Low ESR — 30 mΩ equivalent series resistance measured at 20 °C, 100 kHz, supporting low-loss performance at high switching frequencies.
• High Ripple Current Capability — 160 mA at 120 Hz (low frequency) and 1.6 A at 300 kHz (high frequency) for use where ripple handling is required.
• Leakage Current — Specified leakage current up to 100 µA after standard conditioning.
• Wide Temperature & Endurance — Operating range from -55 °C to +125 °C and rated life of 3000 hours at 125 °C.
• Surface-Mount Package — φ8 × 6.7 mm SMD radial can (package case) with recommended land size 8.3 × 8.3 mm for PCB layout.
• Assembly & Compliance — Lead-free reflow soldering compatible (peak up to 260 °C per datasheet profile) and RoHS compliant; supplied in embossed carrier tape with moisture-proof packing.

Typical Applications

• Switching power supplies and DC–DC converters: Low ESR and high ripple-current rating help smooth output and improve transient response on compact power rails.
• Point-of-load decoupling: Compact SMD can package and high-frequency performance make it suitable for decoupling in high-density PCBs.
• Industrial electronics: Wide temperature range (–55 °C to +125 °C) and 3000-hour life at 125 °C support thermal-stressed, long-life systems.

Unique Advantages

• High ripple handling: 1.6 A at 300 kHz and 160 mA at 120 Hz ensure reliable operation under high switching currents, reducing stress on upstream components.
• Low-loss operation at high frequency: 30 mΩ ESR at 100 kHz minimizes power dissipation and improves efficiency in high-frequency circuits.
• Thermal endurance: Rated for 3000 hours at 125 °C, enabling extended reliable service in elevated-temperature environments.
• SMD-friendly packaging: Embossed carrier tape and moisture-proof packing simplify automated placement and storage for high-volume assembly.
• Reflow compatibility: Conforms to lead-free reflow profiles (260 °C peak per datasheet), allowing standard surface-mount assembly processes.
