RSA1C181MCN1GS

The RSA1C181MCN1GS is a conductive polymer aluminum solid electrolytic capacitor in a compact surface-mount can (φ6.3×5.7 mm). It delivers 180 µF capacitance at 16 V with low ESR and high ripple-current capability, designed for general-purpose electronic power applications.

As a member of Nichicon’s RSA series (lower ESR), this SMD capacitor targets compact power and decoupling designs that require reliable performance across a wide temperature range and a specified 2000-hour endurance at 105°C.

Key Features

• Capacitance & Voltage — 180 µF nominal capacitance with a rated voltage of 16 V and tolerance of -20% to +20%.
• Low ESR — ESR specified at 22 mΩ measured at 20°C/100 kHz, supporting low-loss operation in high-frequency circuits.
• High Ripple Current — Low-frequency ripple current of 330 mA (120 Hz) and high-frequency ripple capability of 3.3 A (300 kHz), enabling efficient smoothing and decoupling.
• Dielectric Performance — Tangent of loss angle (tan δ) of 0.12 at 20°C/120 Hz for stable AC performance.
• Reliability & Lifetime — Rated life/endurance of 2000 hours at 105°C with operating temperature range from -55°C to 105°C.
• Leakage Current — Specified leakage current of 576 µA (measured after standard conditioning).
• Package & Mounting — Surface-mount radial can package, dimensions φ6.3×5.7 mm (L: 5.7 × D: 6.3 mm) with recommended PCB land size 6.5×6.5 mm; supplied in embossed carrier taping with moisture-proof packing.
• RoHS Compliance — Compliant to RoHS directives.

Typical Applications

• Power supply decoupling — Low ESR and high ripple-current capability make this capacitor suitable for local decoupling and bulk smoothing on compact power rails.
• DC‑DC converters — Compact SMD can package and high-frequency ripple handling support use in converter output stages and filter networks.
• Embedded and consumer electronics — General-purpose SMD capacitor for stable filtering and energy storage in size-constrained designs across a wide temperature range.

Unique Advantages

• Compact high-capacitance SMD form — 180 µF in a φ6.3×5.7 mm can helps reduce board footprint while maintaining bulk capacitance.
• Measured low ESR at high frequency — 22 mΩ at 100 kHz supports lower power loss and improved transient response in high-frequency circuits.
• High ripple tolerance — Up to 3.3 A ripple current at high frequency enables robust smoothing in switching power environments.
• Extended thermal endurance — 2000-hour rating at 105°C provides predictable lifetime behavior for demanding thermal conditions.
• Surface-mount assembly ready — Supplied in embossed carrier tape with moisture-proof packing for automated SMT lines.
• RoHS-compliant manufacturing — Meets current RoHS requirements for lead-free assemblies.
