RKS1K270MCNAHHGS

The RKS1K270MCNAHHGS from Nichicon is a surface-mount conductive polymer aluminum solid electrolytic capacitor offering 27 µF capacitance at an 80 V rating. It combines low equivalent series resistance and high allowable ripple current in a compact SMD package for general-purpose electronic designs.

Designed for robust operation across a wide temperature range (−55 °C to 125 °C) and a proven endurance of 3000 hours at 125 °C, this capacitor is suited to applications that require reliable high-frequency performance and long-term stability in a taped, moisture-proof format for automated assembly.

Key Features

• Dielectric / Construction Conductive polymer aluminum solid electrolytic capacitor construction for low loss and stable high-frequency characteristics.
• Capacitance & Tolerance 27 µF nominal capacitance with −20% to +20% tolerance (measured at 20 °C, 120 Hz).
• Rated Voltage 80 V DC rated voltage for higher-voltage power rails and energy storage needs.
• Low Loss (tan δ) tanδ = 0.12 at 20 °C, 120 Hz, supporting efficient operation in AC and ripple environments.
• High-Frequency Performance & ESR ESR of 40 mΩ measured at 20 °C / 100 kHz, enabling effective filtering at high frequencies.
• Ripple Current Capability Low-frequency ripple current 110 mA (120 Hz) and high-frequency ripple current 1.1 A (300 kHz) for demanding power conversion and decoupling tasks.
• Leakage Current Specified leakage current of 108 µA, measured per product conditions.
• Operational Life & Reliability Rated for 3000 hours at 125 °C, demonstrating long endurance under elevated-temperature conditions.
• Package & Assembly Surface-mount radial can (φ8 × 8.7 mm length) supplied in embossed carrier taping with moisture-proof packing for pick-and-place compatibility.
• Regulatory Compliance RoHS compliant.

Typical Applications

• Power supply filtering — Smoothing and bulk decoupling on higher-voltage rails where 80 V rating and high ripple capability are required.
• DC–DC converter output — High-frequency decoupling and energy buffering using low ESR (40 mΩ at 100 kHz) and 1.1 A ripple handling at 300 kHz.
• Industrial electronics — Reliable capacitance and long endurance (3000 h at 125 °C) for control and power modules operating over a wide temperature range.
• General-purpose high-frequency circuits — Applications where low loss (tanδ = 0.12) and compact SMD packaging support dense PCB layouts.

Unique Advantages

• High voltage capability: 80 V rating enables use on higher-voltage rails without up-rating multiple lower-voltage components.
• Low ESR at high frequency: 40 mΩ (100 kHz) reduces conductive losses and improves filtering performance in switching circuits.
• Strong ripple tolerance: 1.1 A high-frequency ripple current rating supports demanding switching supply outputs and decoupling.
• Extended high-temperature endurance: 3000 hours at 125 °C provides predictable lifetime in elevated-temperature environments.
• Assembly-ready packaging: Embossed carrier taping and moisture-proof packing streamline automated placement and inventory handling.
• Low leakage and controlled dissipation: Specified leakage current (108 µA) and tanδ (0.12) aid predictable power budgets and thermal behavior.
