RKS1D330MCNAHFGS

The RKS1D330MCNAHFGS from Nichicon (RKS series) is a conductive polymer aluminum solid electrolytic capacitor in a surface-mount, radial can package. It delivers 33 µF at 20 V with low ESR and high allowable ripple current, targeting board-level power decoupling and high-frequency filtering in space-constrained assemblies.

Engineered for high-reliability operation, this device offers a wide operating temperature range of −55 °C to 125 °C and a rated load life of 3000 hours at 125 °C, with lead-free reflow compatibility up to a 260 °C peak solder temperature and RoHS compliance.

Key Features

• Capacitance & Voltage — 33 µF nominal capacitance at a rated voltage of 20 V, tolerance ±20%.
• Conductive Polymer Electrolyte — Solid conductive polymer construction for stable performance and reduced liquid-electrolyte risks compared with wet electrolytics.
• Low ESR — ESR of 30 mΩ measured at 20 °C / 100 kHz, enabling improved 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 demanding AC/pulse conditions.
• Loss Characteristics — tan δ = 0.12 measured at 20 °C / 120 Hz for predictable dissipation and filtering behavior.
• Leakage & Endurance — Leakage current specified at 100 µA and load life of 3000 hours at 125 °C per datasheet endurance tests.
• Thermal & Reflow Robustness — Operating temperature −55 °C to 125 °C; compatible with lead-free reflow soldering up to a 260 °C peak (pre-heat and time limits apply as per datasheet).
• Compact SMD Can — Package dimension φ8 × 6.7 mm with recommended land size 8.3 × 8.3 mm; available in embossed carrier taping with moisture-proof packing for automated assembly.
• Regulatory — RoHS compliant.

Typical Applications

• Power supply decoupling — Low ESR and high-frequency ripple current handling suit local decoupling on switching regulators and converters.
• High-frequency filtering — 30 mΩ ESR at 100 kHz and tan δ specification support AC and high-speed noise suppression tasks.
• Board-level power conditioning — Compact SMD radial can and 3000-hour life at 125 °C help meet reliability and thermal endurance needs in densely packed electronics.

Unique Advantages

• Improved high-frequency performance: Low ESR (30 mΩ @100 kHz) and measured tan δ make the capacitor well suited for suppressing high-frequency ripple and noise.
• High ripple tolerance: Rated ripple currents of 160 mA (120 Hz) and 1.6 A (300 kHz) provide headroom for dynamic loads and switching environments.
• Long high-temperature life: 3000 hours at 125 °C endurance supports designs that require sustained operation in elevated temperatures.
• Reflow-ready SMD package: Lead-free reflow compatibility up to 260 °C and embossed carrier taping facilitate automated manufacturing and assembly workflows.
• Compact footprint: φ8 × 6.7 mm can with a small recommended land pattern helps save board area while maintaining capacitance and performance.
• RoHS compliant: Meets regulatory requirements for lead-free designs.
