RKS1D330MCNAFEGS

The RKS1D330MCNAFEGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor offering 33 µF capacitance at a 20 V rating. It combines low equivalent series resistance, high allowable ripple current, and extended high-temperature endurance in a compact φ6.3 × 5.8 mm SMD can.

Designed for applications that require low-loss, high-ripple performance and sustained operation at elevated temperatures, this part supports lead-free reflow assembly and long operational life under rated conditions.

Key Features

• Capacitance & Voltage — 33 µF nominal capacitance with a rated voltage of 20 V and tolerance of −20% to +20% (120 Hz, 20°C).
• Low ESR & High-Frequency Performance — ESR of 50 mΩ measured at 100 kHz (20°C) and a high-frequency ripple current rating of 900 mA at 300 kHz, enabling low-loss performance in high-frequency environments.
• Low-Frequency Ripple Capability — 90 mA ripple current rating at 120 Hz for robust low-frequency ripple handling.
• High-Temperature Endurance — Rated operating temperature range −55°C to +125°C with a load-life specification of 3000 hours at 125°C under rated voltage.
• Leakage & Loss — Leakage current specified at 100 µA and tan δ (dissipation factor) of 0.12 measured at 20°C, 120 Hz.
• Compact SMD Can Package — Radial, can-style SMD package with dimensions φ6.3 × 5.8 mm and recommended land size of 6.6 × 6.6 mm; packaged in embossed carrier taping with moisture-proof packing.
• Assembly Compatibility — Compatible with lead-free reflow soldering conditions (peak solder temperature up to 260°C, reflow up to two times) as specified for SMD use.

Typical Applications

• Lead-free reflow SMD assemblies — Suited for surface-mount production flows that require components compatible with 260°C peak lead-free reflow profiles.
• High-frequency circuits — Low ESR (50 mΩ at 100 kHz) and 900 mA ripple capability at 300 kHz support circuits operating at elevated switching frequencies.
• Elevated-temperature environments — Rated for −55°C to +125°C with a 3000-hour endurance at 125°C, making it suitable where prolonged high-temperature operation is required.
• Space-constrained SMD designs — Compact φ6.3 × 5.8 mm can package provides high capacitance density for tight board layouts.

Unique Advantages

• High ripple tolerance: Dual ripple ratings—90 mA at 120 Hz and 900 mA at 300 kHz—allow the part to handle both low- and high-frequency ripple stress.
• Low-loss operation: 50 mΩ ESR at 100 kHz and tan δ of 0.12 (20°C, 120 Hz) reduce power dissipation and improve efficiency in AC/ switching environments.
• Extended high-temperature life: 3000-hour endurance at 125°C under rated voltage supports reliable operation in thermally demanding designs.
• Reflow-ready SMD can: Designed for lead-free reflow (260°C peak, up to two cycles) and supplied in embossed carrier taping with moisture-proof packing for SMT production lines.
• Compact footprint: φ6.3 × 5.8 mm package provides a high-capacitance option where board area is limited.
• RoHS compliant: Meets RoHS requirements for environmentally restricted material content.
