RKS1E470MCNAHHGS

The RKS1E470MCNAHHGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor offering 47 µF capacitance at 25 V. Engineered for SMD assemblies, it combines low ESR and high allowable ripple current with an extended operating range down to –55 °C and up to 125 °C.

Its core value is reliable high-temperature operation and load life endurance—specified for 3,000 hours at 125 °C—making it suitable where compact, low-loss bulk capacitance and stable performance under thermal stress are required.

Key Features

• Dielectric / Core Conductive polymer aluminum solid electrolytic construction for low-loss operation and stable electrical characteristics.
• Capacitance & Tolerance 47 µF nominal capacitance with tolerance ±20% (−20% to +20%) measured at 120 Hz, 20 °C.
• Voltage Rating Rated voltage: 25 V DC.
• Low Equivalent Series Resistance (ESR) ESR 30 mΩ measured at 20 °C / 100 kHz, supporting low-loss performance in high-frequency circuits.
• High Ripple Current Capability Low-frequency ripple current 160 mA at 120 Hz and high-frequency ripple current 1.6 A at 300 kHz to support demanding power conditioning tasks.
• Leakage Current Maximum leakage current 100 µA after standard conditioning.
• Temperature & Endurance Operating range –55 °C to 125 °C with endurance specified at 3,000 hours at 125 °C and rated voltage.
• Package & Mounting Surface-mount radial can package, physical size φ8 × 8.7 mm (L: 8.7 × D: 8 mm) with embossed carrier taping and moisture-proof packing for automated assembly.
• Reflow Compatibility Compatible with lead-free reflow soldering (datasheet specifies peak temperatures and reflow profiles for SMD processing).
• RoHS Compliance Series-level documentation indicates compliance with RoHS directives.

Typical Applications

• Power decoupling and filtering Low ESR and high ripple current ratings make this capacitor suitable for board-level decoupling and smoothing where stable voltage rails are required.
• High-temperature electronic assemblies Rated for operation up to 125 °C with a 3,000-hour load life, addressing thermal-stressed environments and long-duration endurance needs.
• SMD automated production Embossed carrier taping and moisture-proof packaging support SMT pick-and-place and lead-free reflow processes.
• High-frequency power circuits 30 mΩ ESR at 100 kHz and 1.6 A high-frequency ripple capability support applications with significant switching or high-frequency content.

Unique Advantages

• Low ESR for improved transient response: 30 mΩ ESR at 100 kHz reduces voltage drop and dissipation in high-frequency decoupling roles.
• High ripple tolerance across frequency bands: Rated ripple currents of 160 mA (120 Hz) and 1.6 A (300 kHz) allow a single part to address both low- and high-frequency ripple needs.
• Extended high-temperature endurance: 3,000-hour load life at 125 °C provides long-term stability in thermally demanding designs.
• SMD-ready packaging and reflow capability: Embossed carrier taping, moisture-proof packing, and lead-free reflow compatibility streamline automated assembly and processing.
• Compact radial can SMD footprint: φ8 × 8.7 mm dimensions deliver substantial capacitance in a small board area for space-constrained designs.
• Low leakage current: Typical leakage current limited to 100 µA supports low-standby and energy-efficient applications.
