RKS1E330MCNAHGGS

The RKS1E330MCNAHGGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor offering 33 µF capacitance at 25 V. It delivers low ESR and high allowable ripple current in a compact φ8 × 7.7 mm can-style SMD package designed for demanding power-decoupling and filtering duties.

With a wide operating temperature range of −55 °C to 125 °C and a rated load life of 3000 hours at 125 °C, this capacitor targets applications that require high-frequency performance, robust thermal endurance and reliable long-term operation in compact board layouts.

Key Features

• Electrical Performance — 33 µF capacitance at 25 V with ±20% tolerance and tanδ of 0.12 (measured at 20 °C, 120 Hz) for predictable AC behavior.
• Low ESR & High Ripple Capability — ESR of 30 mΩ (measured at 20 °C, 100 kHz) combined with a high-frequency ripple current rating of 1.6 A (at 300 kHz) and 160 mA at 120 Hz for effective smoothing at switching frequencies.
• Thermal Endurance — Rated for continuous operation from −55 °C to 125 °C and qualified for 3000 hours at 125 °C, supporting designs with elevated ambient or internal temperatures.
• Surface-Mount Package — Compact φ8 × 7.7 mm radial can configured for SMD assembly with a recommended land pattern of 8.3 × 8.3 mm; supplied in embossed carrier tape with moisture-proof packing for automated placement.
• Leakage & Reliability — Leakage current specified at 100 µA and endurance/shelf-life characteristics defined per the series datasheet, ensuring stable long-term behavior after soldering and thermal stress.
• Lead-Free Reflow Compatibility — SMD construction designed for lead-free reflow processes with peak temperature compatibility up to 260 °C per manufacturer reflow conditions.
• Environmental Compliance — RoHS compliant for conformity with common lead-free requirements.

Typical Applications

• Power Supply Smoothing — Local energy storage and ripple suppression for DC–DC converters and switching regulators, leveraging the low ESR and high ripple-current rating.
• High-Frequency Decoupling — AC filtering and decoupling at switching frequencies where 100 kHz ESR and 300 kHz ripple performance reduce voltage ripple on power rails.
• Industrial Electronics — Bulk decoupling and smoothing in compact assemblies that require elevated temperature endurance and long life at 125 °C.
• Compact SMD Designs — Board-level energy storage where space is limited but robust ripple handling and reliability are required.

Unique Advantages

• Low ESR for Efficient Filtering: 30 mΩ ESR at 100 kHz enables improved power conversion efficiency and reduced heating in high-frequency applications.
• High Ripple-Current Handling: Rated for 1.6 A at 300 kHz (and 160 mA at 120 Hz), supporting heavy switching loads and fast transient currents.
• Extended High-Temperature Life: 3000 hours at 125 °C provides predictable lifetime performance in thermally demanding environments.
• SMD-Ready Packaging: Embossed carrier tape and moisture-proof packing simplify automated assembly and long-term storage handling.
• Lead-Free Reflow Support: Compatible with lead-free reflow profiles up to 260 °C peak for modern assembly processes.
• Compact Footprint: φ8 × 7.7 mm can format with a small land pattern supports high-density PCB layouts without sacrificing ripple performance.
