RSA1C271MCN1GS

The RSA1C271MCN1GS is a surface-mount conductive polymer aluminum solid electrolytic capacitor offering 270 µF capacitance at a 16 V rating in a compact φ6.3×7.7 mm can. Designed for general-purpose power applications, it combines low equivalent series resistance and high ripple-current capability to support demanding decoupling and bulk-storage needs in compact SMT assemblies.

Key value propositions include low ESR (15 mΩ at 20 °C/100 kHz), high-frequency ripple handling (up to 3.8 A at 300 kHz), and a wide operating temperature range from -55 °C to 105 °C with a rated life of 2000 hours at 105 °C.

Key Features

• Electrical Performance — 270 µF nominal capacitance with ±20% tolerance and tanδ 0.12 (measured at 20 °C, 120 Hz), providing stable reactive behavior for power rails.
• Low ESR & High Ripple Current — ESR of 15 mΩ (20 °C/100 kHz) and rated ripple current of 380 mA at 120 Hz and 3.8 A at 300 kHz, enabling effective smoothing and high-frequency decoupling.
• Voltage & Leakage — Rated for 16 V with a specified leakage current of 864 µA (measurement condition as specified), suitable for a variety of low-voltage power circuits.
• Reliability & Life — Load life rating of 2000 hours at 105 °C under rated voltage, with endurance limits for capacitance, tanδ and ESR defined in the series specification.
• Package & Assembly — Surface-mount radial/can SMD package in φ6.3×7.7 mm, supplied in embossed carrier taping with moisture-proof packing and compatible with lead‑free reflow (260 °C peak).
• Environmental Compliance — RoHS compliant as specified in the product documentation.

Typical Applications

• Power Supply Filtering — Bulk smoothing and post-regulation decoupling on DC–DC converter outputs, leveraging low ESR and high ripple-current capability.
• High-Frequency Decoupling — Local decoupling for power rails in compact SMT designs where 100 kHz–300 kHz ripple is present.
• Embedded Power Modules — Energy storage and transient buffering in compact power modules and board-level power subsystems.

Unique Advantages

• High ripple tolerance: 3.8 A at 300 kHz and 380 mA at 120 Hz allow the capacitor to handle both low- and high-frequency ripple within the same component.
• Very low ESR: 15 mΩ (20 °C/100 kHz) reduces conduction losses and improves power conversion efficiency and thermal behavior on the board.
• Compact SMD can: φ6.3×7.7 mm package delivers 270 µF capacitance in a small footprint for space-constrained designs.
• Extended temperature range and rated life: −55 °C to 105 °C operation with 2000 hours endurance at 105 °C supports robust performance in elevated-temperature environments.
• Assembly-friendly: Supplied in embossed carrier taping with moisture-proof packing and compatible with 260 °C lead-free reflow processes.
• Regulatory compliance: RoHS conformity simplifies integration in RoHS-required product lines.
