RKS1D470MCNAHFGS

The RKS1D470MCNAHFGS is a surface‑mount conductive polymer aluminum solid electrolytic capacitor designed for high‑frequency power applications. It delivers 47 µF at 20 V with low ESR and elevated ripple current capability in a compact φ8 × 6.7 mm SMD can.

Engineered for demanding thermal environments, this RoHS‑compliant capacitor supports an operating range of −55 °C to +125 °C and a rated load life of 3000 hours at 125 °C, making it suitable for compact power modules and high‑frequency decoupling where thermal and ripple performance matter.

Key Features

• Capacitance & Voltage — 47 µF nominal capacitance with a rated voltage of 20 V and tolerance of −20%/+20%.
• Low ESR & High‑Frequency Performance — ESR of 30 mΩ measured at 20 °C, 100 kHz supports high‑frequency filtering and stable impedance at switching frequencies.
• High Ripple Current Capability — Allowable ripple current of 160 mA at 120 Hz and 1.6 A at 300 kHz for robust handling of switching transients and converter output currents.
• Wide Temperature & Long Life — Operating temperature −55 °C to +125 °C with endurance rated to 3000 hours at 125 °C under rated voltage.
• Leakage & Dissipation — Leakage current specified at 100 µA and tan δ (DF) of 0.12 (measured at 20 °C, 120 Hz, 20 V), enabling predictable behavior in bias‑sensitive circuits.
• Surface‑Mount Can Package — Compact φ8 × 6.7 mm radial can SMD with surface mount land size 8.3 × 8.3 mm and embossed carrier taping with moisture proof packing for automated assembly.
• Reflow Compatibility — SMD construction compatible with lead‑free reflow soldering (260 °C peak per manufacturer guidance) for modern assembly processes.

Typical Applications

• DC‑DC converter output filtering — Low ESR and 1.6 A ripple handling enable stable output decoupling in compact switching regulators.
• Power supply decoupling — Effective at high switching frequencies, reducing voltage ripple and improving transient response for power rails.
• Embedded and industrial electronics — Extended −55 °C to +125 °C range and 3000 h life at 125 °C suit thermal‑stress environments and long‑lifetime designs.
• High‑frequency power modules — Small SMD can size and high allowable ripple current allow dense power module designs where board space and thermal performance are constrained.

Unique Advantages

• High ripple tolerance: 1.6 A at 300 kHz specification supports demanding switching loads and reduces the need for multiple parallel components.
• Compact SMD can: φ8 × 6.7 mm package provides a small footprint for space‑constrained PCBs while remaining compatible with automated reflow assembly.
• Thermal endurance: 3000 hours at 125 °C gives designers predictable lifetime behavior in elevated temperature applications.
• Low impedance at frequency: 30 mΩ ESR at 100 kHz improves high‑frequency filtering efficiency and supports cleaner power rails.
• Predictable leakage and dissipation: Specified leakage current and tan δ (DF) allow reliable bias‑sensitive circuit design and component selection.
• RoHS compliant and reflow compatible: Meets lead‑free processing requirements for modern manufacturing and environmental standards.
