RKS1E101MCNAHHGS

The RKS1E101MCNAHHGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor in Nichicon's RKS series, rated 100 µF at 25 V. It delivers low equivalent series resistance and high allowable ripple current in a compact radial can SMD package optimized for demanding PCB power circuits.

Designed for applications that require stable performance at elevated temperatures, this part offers a 3000-hour load life at 125°C, low leakage, and compatibility with lead-free reflow soldering up to a 260°C peak.

Key Features

• Capacitance and tolerance — 100 µF nominal capacitance with tolerance of -20% to +20% at 120 Hz, 20°C.
• Rated voltage — 25 V DC rated voltage suitable for many PCB power rail uses.
• Low ESR and loss — ESR specified at 30 mΩ (20°C, 100 kHz) and tanδ 0.12 (20°C, 120 Hz), enabling efficient high-frequency performance.
• High ripple current capability — Low-frequency ripple current 160 mA (120 Hz) and high-frequency ripple current 1.6 A (300 kHz) for smoothing and decoupling in switched-power circuits.
• Wide operating temperature and long life — Rated for -55°C to +125°C with an endurance (load life) of 3000 hours at 125°C.
• Leakage current — Specified leakage current up to 125 µA after standard conditioning.
• SMD radial can package — Compact φ8 × 8.7 mm package (L: 8.7 × D: 8 mm) with surface-mount land recommendation 8.3 × 8.3 mm; supplied in embossed carrier tape with moisture-proof packing.
• Reflow compatibility — Supports lead-free reflow profiles up to a 260°C peak (measurement at capacitor top) with allowable reflow cycles per datasheet.
• RoHS-compliant series — The RKS series is described as compliant to RoHS directives in the datasheet.

Typical Applications

• Power-supply decoupling — Low ESR and high-frequency ripple current capability make this capacitor well suited for stabilizing and decoupling PCB power rails.
• DC–DC converter output filtering — High allowable ripple current and compact SMD can package support output-stage smoothing in switching regulator designs.
• High-temperature electronics — Extended 3000-hour life at 125°C enables use in designs where prolonged elevated-temperature operation is required.

Unique Advantages

• High ripple handling — 1.6 A at 300 kHz (high-frequency) and 160 mA at 120 Hz (low-frequency) provide headroom for demanding switching environments.
• Low ESR for efficient performance — 30 mΩ ESR at 100 kHz reduces loss and heat generation in high-frequency circuits.
• Extended high-temperature life — 3000-hour endurance at 125°C supports longer service life in thermally stressed designs.
• Compact SMD radial-can footprint — φ8 × 8.7 mm package balances capacitance and board space for densely populated PCBs.
• Reflow-ready packaging — Embossed carrier taping and moisture-proof packing streamline automated surface-mount assembly and storage.
• Conductive polymer chemistry — Solid electrolyte construction contributes to low loss and stable high-frequency behavior.
