RKS1E330MCNAHFGS

The RKS1E330MCNAHFGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor designed for high-ripple, high-temperature applications. It provides 33 µF capacitance at 25 V with low ESR and high allowable ripple current in a compact radial SMD can (φ8 × 6.7 mm).

Targeted at power-dense and industrial electronics, this part delivers long-term stability (3000 hours at 125°C) and packaging suited for automated assembly, making it ideal where thermal endurance and reliable power smoothing are required.

Key Features

• Capacitance & Voltage — 33 µF nominal capacitance with a rated voltage of 25 V and capacitance tolerance of −20% to +20%.
• Low Loss / Low ESR — Tangent of loss angle (tanδ) of 0.12 (20°C, 120 Hz) and ESR of 30 mΩ measured at 20°C/100 kHz, supporting efficient power delivery and reduced heating.
• High Ripple Current — Designed for significant ripple handling: 160 mA at 120 Hz and 1.6 A at 300 kHz, suitable for switching regulators and power filtering.
• Thermal Endurance — Rated operating temperature −55°C to +125°C with a specified load life of 3000 hours at 125°C for sustained high-temperature reliability.
• Leakage Current — Low leakage current specification: 100 µA (after standard conditioning), aiding in overall system efficiency.
• Surface-Mount Radial Can — Compact φ8 × 6.7 mm package (L × D) in an SMD-compatible radial can with embossed carrier taping and moisture-proof packing for automated assembly and storage.
• RoHS Compliant — Conforms to RoHS requirements as stated in the product documentation.

Typical Applications

• Power-supply output filtering — Use for smoothing and energy storage on DC–DC converter outputs where low ESR and high ripple capability improve regulator stability and thermal performance.
• Switching regulator decoupling — Supports high-frequency decoupling in switching power stages, leveraging 1.6 A ripple capability at 300 kHz and low ESR to reduce voltage ripple.
• Industrial and telecom power modules — Suitable for power modules operating at elevated temperatures given its 3000-hour endurance at 125°C and wide −55°C to +125°C operating range.
• LED driver and power-control circuits — Provides reliable smoothing and transient handling in LED drivers and electronic control units that demand robust ripple handling and thermal stability.

Unique Advantages

• High thermal reliability: 3000-hour load life at 125°C provides predictable long-term performance in hot operating environments.
• Superior ripple handling: Dual-frequency ripple specs (160 mA at 120 Hz, 1.6 A at 300 kHz) make it effective across both low- and high-frequency power systems.
• Low ESR for efficiency: 30 mΩ ESR at 100 kHz reduces losses and self-heating, improving overall power conversion efficiency.
• SMD-ready packaging: Embossed carrier taping and moisture-proof packing streamline automated placement and inventory handling.
• Compact radial can form factor: φ8 × 6.7 mm size offers a space-efficient solution for board-level power density requirements.
• Regulatory compliance: RoHS compliance supports use in designs targeting restricted-substance regulations.
