RKS1E330MCNAFGGS

The RKS1E330MCNAFGGS is a surface-mount conductive polymer aluminum electrolytic capacitor from Nichicon's RKS series. It delivers 33 µF capacitance at a 25 V rating in a compact φ6.3 × 7.7 mm SMD can package designed for high-frequency, high-ripple current applications.

Engineered for demanding thermal and ripple environments, this part combines low ESR and a wide operating temperature range (−55 °C to +125 °C) with a 3000-hour endurance at 125 °C, making it suitable for compact power subsystems and high-density assemblies that require reliable decoupling and bulk energy storage.

Key Features

• Capacitance & Tolerance — 33 µF nominal capacitance with a tolerance of −20% to +20% (measured at 20 °C, 120 Hz).
• Rated Voltage — 25 V rated voltage suitable for many point-of-load and intermediate bus applications.
• Low ESR & High-Frequency Performance — ESR of 30 mΩ at 100 kHz and high-frequency ripple current capability (1.4 A at 300 kHz) for improved regulation and lower losses in switching environments.
• Ripple Current Capability — Low-frequency ripple current rating of 140 mA at 120 Hz and high-frequency rating of 1.4 A at 300 kHz, enabling robust handling of both low- and high-frequency ripple components.
• Thermal Endurance — Rated for operation from −55 °C to +125 °C with a specified load life of 3000 hours at 125 °C, supporting long-term stability in elevated-temperature assemblies.
• Loss and Leakage Characteristics — Tangent of loss angle (tan δ) of 0.12 (20 °C, 120 Hz) and leakage current of 100 µA, supporting stable performance in precision power applications.
• SMD Package & Reflow Compatibility — φ6.3 × 7.7 mm radial can SMD footprint with surface-mount land recommendation (6.6 × 6.6 mm); designed for lead-free reflow soldering up to a 260 °C peak per the datasheet.
• Packaging & Compliance — Supplied in embossed carrier taping with moisture-proof packing and designated as mass production; RoHS compliant.

Typical Applications

• Power supply decoupling — Local decoupling and bulk smoothing for switching regulators where low ESR and high ripple capability improve transient response and regulation stability.
• DC–DC converter outputs — Output filtering for point-of-load converters and power modules operating at high switching frequencies, leveraging the 1.4 A high-frequency ripple rating.
• High-frequency power modules — Use in compact SMD power assemblies that require low-loss capacitors and reliable operation up to 125 °C.
• Compact industrial and communications electronics — Space-constrained boards that need durable, high-capacitance SMD solutions with reflow compatibility and long-term endurance.

Unique Advantages

• High ripple-handling capability: The combination of 1.4 A at 300 kHz and 140 mA at 120 Hz supports a wide range of ripple profiles, reducing thermal stress and improving power stage reliability.
• Low ESR for tighter regulation: 30 mΩ ESR at 100 kHz minimizes voltage drop and power loss in high-frequency circuits, aiding converter efficiency and transient performance.
• Extended high-temperature life: Rated 3000 hours at 125 °C, providing predictable end-of-life behavior in elevated-temperature environments.
• Reflow-ready SMD can: Designed for lead-free reflow up to 260 °C, simplifying assembly in modern SMT production flows while maintaining performance after soldering.
• Compact form factor: φ6.3 × 7.7 mm package delivers significant capacitance in a small footprint for high-density board layouts.
• Production-ready supply: Supplied in embossed carrier taping with moisture-proof packing and listed as mass production, easing BOM sourcing and assembly logistics.
