RKS1D331MCNAJJGS

The RKS1D331MCNAJJGS from Nichicon is a surface-mount conductive-polymer aluminum electrolytic capacitor in the RKS series, providing 330 µF nominal capacitance at 20 V. Designed for general-purpose SMD applications, it combines high capacitance in a compact φ10 × 10 mm can-style package with specifications optimized for high ripple current and elevated-temperature operation.

Key value propositions include low equivalent series resistance (20 mΩ at 100 kHz, 20°C), high allowable ripple current (2.0 A at high frequency), and long load life (3000 hours at 125°C), offering engineers a robust option for power filtering and bulk capacitance in space-constrained designs.

Key Features

• Core Technology — Conductive Polymer Aluminum: Solid conductive-polymer electrolyte for stable electrical characteristics and improved ripple handling compared with traditional wet electrolytes.
• Capacitance and Tolerance: 330 µF nominal with ±20% tolerance at 120 Hz, 20°C, supporting bulk energy storage and smoothing functions.
• Rated Voltage: 20 V working voltage suitable for low-voltage power rails and decoupling tasks.
• Low ESR and Loss Tangent: ESR of 20 mΩ (measured at 100 kHz, 20°C) and tan δ of 0.12 (20°C, 120 Hz), enabling efficient high-frequency performance and reduced I2R heating.
• High Ripple Current Capability: 200 mA at 120 Hz (low frequency) and 2.0 A at 300 kHz (high frequency), allowing effective handling of switching converter currents and ripple.
• Extended High-Temperature Life: Rated for 3000 hours at 125°C, providing extended endurance in elevated-temperature environments.
• Wide Operating Temperature: −55°C to +125°C for broad environmental tolerance.
• Surface-Mount Radial Can Package: φ10 × 10 mm SMD can (radial, can-style) packaged in embossed carrier taping with moisture-proof packing for automated assembly.
• Polarized Component: Polar capacitor suitable for applications that require a defined polarity.
• Regulatory Compliance: RoHS compliant.

Typical Applications

• Power supply filtering: Bulk smoothing and ripple reduction on low-voltage rails where high ripple current handling and low ESR are required.
• Switching converters: High-frequency ripple handling (2.0 A at 300 kHz) for DC–DC converters and switching regulator output stages.
• Industrial and embedded electronics: Board-level bulk capacitance in compact SMD form for equipment operating across −55°C to +125°C and requiring long-term load life.

Unique Advantages

• High ripple tolerance: Specified low- and high-frequency ripple currents support demanding switching and power-conversion environments, reducing the need for multiple parallel components.
• Low ESR for efficient operation: 20 mΩ ESR at 100 kHz lowers conduction losses and thermal rise under ripple conditions.
• Compact SMD can with automated packaging: φ10 × 10 mm SMD radial can in embossed carrier taping and moisture-proof packing streamlines pick-and-place and reflow assembly.
• Extended high-temperature endurance: 3000 hours at 125°C provides predictable lifetime behavior in elevated-temperature applications.
• Stable electrical characteristics: Specified tan δ and leakage current figures support predictable filtering and decoupling performance in system designs.
• RoHS compliant: Meets environmental directive requirements for restricted substances.
