RFS0E181MCN1GS

The RFS0E181MCN1GS is a conductive polymer aluminum solid electrolytic capacitor in a surface-mount can package, offering 180 µF capacitance at a 2.5 V rating. It is designed for general-purpose electronic designs that require low equivalent series resistance and high ripple-current capability in a compact SMD footprint.

Key value propositions include low ESR (21 mΩ at 20°C/100 kHz), high rated ripple current (2.67 A at 100 kHz), RoHS compliance, and a 2000-hour load life at 105°C—features that support reliable power filtering in compact assemblies.

Key Features

• Capacitance & Voltage — 180 µF nominal capacitance with ±20% tolerance at 120 Hz, rated for 2.5 V operation.
• Low Loss / High Frequency Performance — tanδ of 0.12 (20°C, 120 Hz) and ESR of 21 mΩ measured at 20°C/100 kHz for low dissipation and stable AC behavior.
• High Ripple Current — Rated ripple current of 2.67 A at 100 kHz (105°C) and 267 mA at 120 Hz to handle sustained AC stress in power circuits.
• Leakage Current — Specified leakage current of 300 µA (measured at 20°C after 2 minutes) for predictable standby behavior.
• Thermal Endurance — Operates from −55°C to +105°C with a rated load life of 2000 hours at 105°C.
• Surface-Mount Package & Assembly — φ5 × 5.7 mm can-style SMD (radial, can — SMD); supplied in embossed carrier taping with moisture-proof packing and compatible with lead-free reflow up to 260°C peak.
• Regulatory — Compliant to RoHS directives.

Typical Applications

• Power supply filtering — Bulk smoothing and decoupling in compact power rails where low ESR (21 mΩ) and high ripple capability (2.67 A at 100 kHz) reduce voltage ripple and heat dissipation.
• Compact SMD power modules — Small φ5×5.7 mm can package and embossed carrier taping support automated placement in densely populated boards and module builds.
• General-purpose electronics — Suitable for designs requiring stable capacitance across −55°C to +105°C and a long-term endurance of 2000 hours at elevated temperature.

Unique Advantages

• Low ESR for reduced losses: 21 mΩ ESR at 100 kHz limits I²R heating and improves power-conversion efficiency under AC stress.
• High ripple-current rating: 2.67 A (105°C/100 kHz) lets the capacitor handle substantial AC currents common in switching supplies and converters.
• Compact SMD can: φ5×5.7 mm size delivers high capacitance in a small footprint for space-constrained PCBs.
• Thermal robustness: −55°C to +105°C operating range and 2000-hour life at 105°C support long-term reliability in elevated-temperature environments.
• Assembly-ready packaging: Embossed carrier taping with moisture-proof packing and lead-free reflow compatibility streamline automated manufacturing.
• Predictable leakage behavior: Specified 300 µA leakage (20°C, after 2 minutes) for controlled standby and bias conditions.

Why Choose RFS0E181MCN1GS?

RFS0E181MCN1GS combines conductive-polymer aluminum chemistry with a surface-mount can package to deliver a balance of high capacitance, low ESR, and robust ripple-current handling in a compact footprint.
