RSS1E270MCN1GS

The RSS1E270MCN1GS is a surface-mount conductive polymer aluminum solid electrolytic capacitor from Nichicon’s RSS series. It provides 27 µF capacitance at a 25 V rating in a compact φ6.3 × 5.7 mm SMD can, designed for general-purpose surface-mount applications.

Key value propositions include low equivalent series resistance (ESR), high ripple-current capability, and a robust 2,000 hour load life at 105°C—making it suitable for designs that require stable filtering and reliable performance in elevated-temperature environments.

Key Features

• Capacitance & Voltage — 27 µF nominal capacitance with ±20% tolerance at 120 Hz, rated for 25 V operation.
• Conductive Polymer Dielectric — Solid electrolytic construction for reduced ESR and improved ripple performance compared with traditional wet aluminum types.
• Low ESR — ESR of 40 mΩ measured at 20°C / 100 kHz, contributing to lower losses and improved power-handling in high-frequency circuits.
• High Ripple-Current Capability — Rated ripple current of 260 mA at 120 Hz (low frequency) and 2.6 A at 300 kHz (high frequency), enabling effective smoothing in both low- and high-frequency environments.
• Loss Characteristic — tanδ (DF) of 0.12 measured at 20°C, 120 Hz, supporting predictable loss behavior in AC conditions.
• Leakage Current — Specified leakage current of 135 µA after 2 minutes at rated voltage and 20°C.
• Extended Load Life — Endurance rated to 2,000 hours at 105°C under rated voltage, with specified limits for capacitance change, tanδ, ESR and leakage after test.
• Temperature Range — Operating from −55°C to +105°C to cover a wide range of environmental conditions.
• SMD Package & Assembly — Compact package dimension φ6.3 × 5.7 mm with recommended land size 6.6 × 6.6 mm; supplied in embossed carrier taping with moisture-proof packing for automated assembly.
• RoHS Compliant — Manufactured in conformance with RoHS requirements.
• Lead-Free Reflow Compatible — Designed to withstand lead-free reflow soldering conditions (260°C peak) as noted in the RSS series documentation.

Typical Applications

• General-purpose power circuits — Fits surface-mount designs needing bulk capacitance and stable filtering across a wide temperature range.
• High-ripple environments — Low ESR and high ripple-current ratings support applications where repeated or high-frequency ripple must be absorbed.
• Compact SMD assemblies — Small φ6.3 × 5.7 mm package for space-constrained boards while maintaining robust electrical performance.

Unique Advantages

• Low-loss operation: 40 mΩ ESR at 100 kHz and tanδ 0.12 (120 Hz) reduce power dissipation and thermal stress in high-frequency circuits.
• High ripple tolerance: 2.6 A ripple current rating at 300 kHz and 260 mA at 120 Hz enable reliable smoothing in both switching and line-frequency contexts.
• Elevated-temperature endurance: 2,000 hour life at 105°C provides predictable long-term behavior under high thermal load.
• Compact, assembly-ready package: φ6.3 × 5.7 mm SMD can with embossed carrier taping and moisture-proof packing streamlines automated placement and handling.
• Manufacturing quality and compliance: Produced by Nichicon and RoHS-compliant for regulatory alignment in commercial electronics.

Why Choose RSS1E270MCN1GS?

The RSS1E270MCN1GS balances compact form factor with performance attributes that matter for power filtering and decoupling in surface-mount designs: a 27 µF conductive-polymer aluminum core, low ESR (40 mΩ at 100 kHz), and strong ripple-current capability (up to 2.6 A at 300 kHz). Its −55°C to +105°C operating range and 2,000 hour endurance at 105°C make it a reliable option where sustained elevated-temperature performance is required.

This part is well suited to engineers and procurement teams who need a proven, production-ready SMD electrolytic capacitor from Nichicon for general-purpose applications requiring low loss, compact packaging, and long-term stability.
