RKS1E270MCNAFEGS

The RKS1E270MCNAFEGS is a surface-mount conductive polymer aluminum electrolytic capacitor engineered for compact, high-ripple-current applications. It delivers 27 µF at 25 V with low ESR and a wide operating temperature range for sustained performance in thermally demanding assemblies.

This part is optimized for PCB-mounted power sections where long high-temperature endurance and robust ripple handling are required, offering a rated life of 3000 hours at 125°C and RoHS compliance.

Key Features

• Capacitance & Voltage — 27 µF rated capacitance at 25 V with tolerance of −20% to +20% (measured at 120 Hz, 20°C).
• Low ESR — ESR of 50 mΩ measured at 100 kHz and 20°C supports efficient power delivery and reduced loss in high-frequency circuits.
• High Ripple Current Capability — 90 mA at 120 Hz (low frequency) and 900 mA at 300 kHz (high frequency) for demanding AC ripple and switching environments.
• High-Temperature Endurance — Designed for 3000 hours load life at 125°C, providing long-term stability under elevated temperature stress.
• Leakage & Dissipation — Leakage current specified at 100 µA and tan δ (loss tangent) of 0.12 at 120 Hz, 20°C for predictable leakage and dissipation behavior.
• SMD Can Package — Radial can-style SMD (φ6.3 × 5.8 mm) in embossed carrier taping with moisture-proof packing for automated placement and reflow processing.
• Wide Operating Temperature — Rated for −55°C to +125°C to cover a broad range of thermal conditions.

Typical Applications

• Board-level power rails — Filtering and smoothing on compact SMD power domains where low ESR and high ripple capability reduce voltage ripple and thermal loss.
• Switching power supplies — Bulk and output-stage decoupling in switching regulators that require high-frequency ripple handling and stable ESR.
• Power management modules — Local energy storage for DC–DC converters and regulator modules operating in elevated-temperature environments.

Unique Advantages

• Extended high-temperature life: 3000 hours at 125°C supports durable performance in thermally stressed assemblies, reducing maintenance and replacement cycles.
• High ripple tolerance: Specified ripple currents at both low and high frequencies enable reliable operation with switching and pulse loads.
• Low-loss operation: 50 mΩ ESR and tan δ of 0.12 at 120 Hz minimize dissipation, improving efficiency in power delivery circuits.
• Compact SMD form factor: φ6.3 × 5.8 mm can-style SMD package with embossed carrier taping simplifies automated assembly while conserving PCB area.
• Predictable leakage behavior: Leakage current specified at 100 µA for easier thermal and bias budgeting in precision power designs.
• RoHS compliant: Built to meet RoHS requirements for regulatory and environmental compliance.
