RKS1V470MCNAFEGS

The RKS1V470MCNAFEGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor offering 47 µF capacitance at a 35 V rating. It combines low ESR and high allowable ripple current in a compact SMD can (φ6.3 × 5.8 mm) designed for temperature-stressed, high-reliability applications.

Engineered for demanding thermal and ripple environments, this part supports operation from −55 °C to 125 °C and features a rated load life of 3000 hours at 125 °C. Packaging is optimized for automated assembly with embossed carrier taping and moisture proof packing.

Key Features

• Capacitance and Voltage — 47 µF nominal capacitance with a rated voltage of 35 V and capacitance tolerance of −20% to +20% at 20 °C, 120 Hz.
• Low ESR — Equivalent series resistance of 60 mΩ measured at 20 °C, 100 kHz, supporting efficient high-frequency performance.
• High Ripple Current Capability — Supports 90 mA at 120 Hz (low-frequency) and 900 mA at 300 kHz (high-frequency), suitable for power-stage filtering and decoupling.
• Wide Temperature Range & Endurance — Rated for −55 °C to 125 °C with an endurance (load life) of 3000 hours at 125 °C.
• Leakage & Loss Characteristics — Leakage current specified at 100 µA and tan δ (DF) of 0.12 measured at 20 °C, 120 Hz.
• SMD Can Package — Radial, can-style SMD package sized φ6.3 × 5.8 mm with surface mount land recommendation 6.6 × 6.6 mm for compact board layouts.
• Assembly-Ready Packaging — Supplied on embossed carrier tape with moisture proof packing for pick-and-place and reflow processes.
• RoHS Compliant — Conforms to RoHS requirements as stated in product data.

Typical Applications

• Power supply decoupling and smoothing — Low ESR (60 mΩ) and high ripple tolerance (up to 900 mA at 300 kHz) make this capacitor well suited for decoupling and smoothing in compact power rails.
• DC-DC converter output filtering — 47 µF capacitance and strong high-frequency performance support output filtering in tight-layout converter designs.
• Industrial and high-temperature electronics — Rated to operate up to 125 °C with a 3000-hour endurance at that temperature, appropriate for equipment exposed to elevated operating temperatures.
• Compact SMD power modules — Small φ6.3 × 5.8 mm SMD can and embossed tape packaging simplify integration into space-constrained power modules and SMT assembly flows.

Unique Advantages

• High-temperature endurance: 3000 hours at 125 °C provides proven life performance for thermal-stressed applications.
• High ripple handling: Specified ripple currents at both low and high frequencies (90 mA @ 120 Hz, 900 mA @ 300 kHz) reduce voltage ripple and improve regulator stability.
• Low ESR for improved efficiency: 60 mΩ ESR at 100 kHz lowers I²R losses and supports stable operation in high-frequency circuits.
• Compact SMD can: φ6.3 × 5.8 mm footprint delivers significant capacitance in a small board area for dense designs.
• Assembly-friendly packaging: Embossed carrier taping and moisture proof packing streamline automated placement and protect parts during storage.
• Verified leakage and loss characteristics: Leakage current (100 µA) and tan δ (0.12 @ 20 °C, 120 Hz) give predictable behavior in power designs.
