RKS1D101MCNAHFGS

The RKS1D101MCNAHFGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor designed for SMD power circuitry that requires low impedance, high ripple capability and extended high-temperature endurance. It delivers 100 µF at 20 V in a compact φ8 × 6.7 mm radial can SMD package with embossed carrier taping and moisture-proof packing for automated assembly.

Key value propositions include low ESR for high-frequency performance, high allowable ripple current, and a rated load life of 3000 hours at 125°C—enabling reliable operation in elevated-temperature electronics and densely packaged power modules.

Key Features

• Capacitance and Tolerance — 100 µF nominal capacitance with a tolerance of -20% to +20% (measured at 20°C, 120 Hz).
• Rated Voltage — 20 V DC operating voltage.
• Low ESR & High-Frequency Performance — ESR specified at 30 mΩ measured at 20°C/100 kHz, supporting high-frequency filtering and decoupling.
• High Allowable Ripple Current — Low-frequency ripple current 160 mA at 120 Hz and high-frequency ripple current 1.6 A at 300 kHz for demanding power applications.
• Loss Angle (tan δ) — tan δ = 0.12 measured at 20°C, 120 Hz, indicating controlled dissipation characteristics.
• Leakage Current — Specified leakage current up to 100 µA after standard conditioning.
• Extended High-Temperature Life — Rated for 3000 hours endurance at 125°C under rated voltage.
• Wide Operating Temperature Range — −55°C to +125°C.
• Surface-Mount Package & Reflow Compatible — φ8 × 6.7 mm radial can SMD; compatible with lead-free reflow soldering (260°C peak correspondence) and supplied in embossed carrier taping with moisture-proof packing.
• Environmental Compliance — RoHS compliant.

Typical Applications

• High-ripple power circuits — Provides low ESR and high allowable ripple current for power lines and modules that require effective AC ripple suppression.
• Elevated-temperature electronics — Rated endurance of 3000 hours at 125°C supports use in equipment exposed to sustained high ambient temperatures.
• SMD power assemblies — Compact radial can SMD package and embossed carrier taping streamline automated placement in surface-mount power modules and assemblies.
• High-frequency filtering — Low ESR at 100 kHz and specified tan δ make it suitable for high-frequency decoupling and filtering tasks in power delivery networks.

Unique Advantages

• Low impedance at frequency: 30 mΩ ESR at 100 kHz minimizes voltage ripple and improves transient response in high-frequency circuits.
• High ripple handling: 1.6 A high-frequency ripple current rating supports heavier AC stress on power rails without premature degradation.
• Long life at elevated temperature: 3000-hour rating at 125°C provides predictable endurance for designs that operate in hot environments.
• Compact SMD form factor: φ8 × 6.7 mm radial can SMD saves board area while remaining compatible with lead-free reflow processes.
• Predictable dissipation: tan δ of 0.12 (20°C, 120 Hz) helps designers estimate power loss and thermal behavior.
• Assembly-ready packaging: Embossed carrier taping with moisture-proof packing facilitates automated surface-mount production flows.
