RKS1E330MCNAHJGS

The RKS1E330MCNAHJGS from Nichicon is a surface-mount conductive polymer aluminum electrolytic capacitor in the RKS series, offering 33 µF capacitance at 25 V in a compact φ8 × 10 mm can-style SMD package. Designed for general-purpose power decoupling and filtering, it combines low ESR and high allowable ripple current with a wide operating temperature range and long life to support demanding SMD power designs.

Key Features

• Capacitance & Voltage — 33 µF rated capacitance at 25 V with tolerance of -20% to 20%.
• Conductive polymer construction — Solid electrolyte construction (conductive polymer) from the RKS series for stable electrical characteristics.
• Low ESR — ESR of 27 mΩ measured at 20°C and 100 kHz, enabling efficient power delivery and reduced heat generation.
• High allowable ripple current — 160 mA at 120 Hz (low frequency) and 1.6 A at 300 kHz (high frequency) to handle dynamic load conditions.
• Leakage current — Specified leakage current up to 100 µA after standard conditioning.
• Extended temperature and life — Rated for -55°C to 125°C and endurance of 3000 hours at 125°C.
• Package & mounting — Surface-mount radial can (SMD) in φ8 × 10 mm format; packaged in embossed carrier taping with moisture-proof packing for automated assembly.
• Reflow compatibility and compliance — SMD type compatible with lead-free reflow soldering conditions up to a 260°C peak; the RKS series is stated as RoHS-compliant in the datasheet.

Typical Applications

• General-purpose power filtering — Compact 33 µF, 25 V SMD capacitor for decoupling and smoothing on power rails, benefiting from low ESR (27 mΩ @100 kHz) and high ripple capability.
• DC–DC converter output smoothing — Supports high-frequency ripple currents (1.6 A @300 kHz) for improved stability on converter outputs in space-constrained SMD layouts.
• Power module and board-level decoupling — Small φ8 × 10 mm can-style package and embossed carrier taping simplify placement in automated assembly while delivering reliable bulk capacitance.

Unique Advantages

• High ripple tolerance: Rated ripple currents of 160 mA (120 Hz) and 1.6 A (300 kHz) allow the capacitor to handle both low- and high-frequency load fluctuations.
• Low-loss performance: Low ESR (27 mΩ @100 kHz) and specified tanδ support efficient power transfer and reduced dissipation under load.
• Thermal and lifecycle robustness: Wide -55°C to 125°C operating range with a 3000-hour endurance rating at 125°C provides predictable long-term behavior in high-temperature environments.
• SMD-ready packaging: Embossed carrier taping and moisture-proof packing streamline surface-mount assembly for volume production.
• Reflow process compatibility: Designed for lead-free reflow soldering up to a 260°C peak, enabling standard SMD assembly flows.
• Clear specification set: Measured leakage current (100 µA) and defined tolerance (-20% to 20%) make performance trade-offs transparent for design trade studies.
