RKS1E470MCNAFGGS

The RKS1E470MCNAFGGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor offering 47 µF capacitance at a rated voltage of 25 V. Engineered for applications that require low ESR and high ripple handling in compact SMD footprint, it combines high-frequency performance with extended thermal endurance.

With a wide operating temperature range of −55°C to 125°C and a rated load life of 3000 hours at 125°C, this device targets power delivery, decoupling and filtering tasks in industrial and embedded electronic systems where stable performance under elevated temperature and high ripple conditions is required.

Key Features

• Capacitance & Voltage: 47 µF nominal capacitance with a tolerance of −20% to +20% at 20°C, 120 Hz, and a rated voltage of 25 V for DC bus and decoupling duties.
• Low ESR & High Ripple Capability: ESR of 30 mΩ (measured at 20°C, 100 kHz) and high-frequency ripple current rating of 1.4 A (300 kHz), supporting efficient high-frequency filtering and power-stage smoothing.
• Low-Frequency Ripple & Leakage: 140 mA allowable ripple at 120 Hz and a maximum leakage current of 100 µA, enabling predictable behavior in bulk or intermediate filtering roles.
• Thermal Endurance: Rated operating temperature from −55°C to 125°C with a guaranteed load life of 3000 hours at 125°C, delivering long-term stability in high-temperature environments.
• SMD Package & Assembly Ready: Compact can-style SMD package (Ø6.3 × 7.7 mm) supplied in embossed carrier taping with moisture-proof packing and compatible with lead‑free reflow soldering (260°C peak reflow conditions as specified).
• Regulatory Compliance: RoHS compliant per provided environmental status.

Typical Applications

• Power conversion and regulation: Smoothing and output decoupling for DC‑DC converters and power modules that need high ripple capacity and low ESR at high frequencies.
• Embedded and industrial electronics: Bulk and bypass filtering in controllers and embedded systems operating across wide temperature ranges up to 125°C.
• High-frequency power stages: Local decoupling at switching nodes where 100 kHz+ ESR performance and 300 kHz ripple handling improve transient response and efficiency.

Unique Advantages

• Low ESR for improved efficiency: 30 mΩ ESR at 100 kHz reduces losses and voltage drop under high-frequency switching conditions.
• High high-frequency ripple capability: 1.4 A ripple current rating at 300 kHz supports demanding switching-power applications without rapid heating.
• High-temperature reliability: 3000-hour rated life at 125°C provides predictable endurance in elevated-temperature environments.
• SMD-ready packaging: Embossed carrier tape and moisture-proof packing streamline automated assembly and storage handling for production lines.
• Predictable leakage and ripple specs: Defined leakage current (100 µA) and low-frequency ripple rating (140 mA at 120 Hz) simplify thermal and power-budget calculations.
• Lead‑free reflow compatible: Constructed for lead-free reflow profiles up to 260°C for modern surface-mount assembly processes.
