RPA1C181MCN1GS

The RPA1C181MCN1GS is a conductive polymer aluminum solid electrolytic capacitor in a surface-mount radial can package. It delivers 180 µF capacitance at a 16 V rating with low equivalent series resistance and high ripple-current capability for general-purpose surface-mount applications.

Designed for engineers requiring compact power capacitors, this part combines a φ10×7.7 mm SMD can, RoHS compliance, and a rated operating range of –55 °C to +105 °C with a 2000-hour endurance at 105 °C.

Key Features

• Capacitance & Voltage — 180 µF nominal capacitance with a 16 V rated voltage and ±20% tolerance, suitable for a range of general-purpose power designs.
• Conductive Polymer Electrolyte — Solid conductive polymer construction for stable electrical characteristics and low loss (tanδ = 0.12 at 20 °C, 120 Hz).
• Low ESR — ESR of 20 mΩ measured at 20 °C/100 kHz, enabling efficient high-frequency performance and reduced dissipation in power applications.
• High Ripple Current — Rated ripple current of 360 mA at 120 Hz (low frequency) and 3.6 A at 300 kHz (high frequency) to handle demanding AC load conditions.
• Robust Temperature and Lifetime — Operating temperature range from –55 °C to +105 °C with a rated lifetime/endurance of 2000 hours at 105 °C.
• Surface-Mount Radial Can — φ10×7.7 mm SMD can (package case radial, can - SMD) in embossed carrier taping with moisture-proof packing for automated assembly.
• Leakage and Reliability — Specified leakage current of 576 µA (after 2 minutes at 20 °C) and endurance characteristics defined per the series test conditions.
• RoHS Compliance — Declared RoHS compliant for environmental conformance.

Typical Applications

• General Purpose Power Circuits — Bulk and decoupling capacitance in surface-mount power supply sections where a 16 V, 180 µF capacitor with low ESR is required.
• High-Frequency Filtering — AC ripple handling and smoothing in circuits that require high ripple-current capability up to 3.6 A at 300 kHz.
• Compact SMD Designs — Surface-mount radial can for space-constrained boards that need a robust electrolytic solution across –55 °C to +105 °C.

Unique Advantages

• High ripple capability tied to low ESR — 20 mΩ ESR at 100 kHz and 3.6 A high-frequency ripple rating reduce heating and improve performance in high-switching environments.
• Wide operating temperature window — –55 °C to +105 °C supports deployment across a broad range of thermal conditions without compromising specified endurance.
• Solid conductive polymer chemistry — Provides stable tanδ (0.12 at 20 °C/120 Hz) and predictable behavior for design margin control.
• SMD packaging for automated assembly — Embossed carrier taping and moisture-proof packing facilitate high-volume surface-mount production flows.
• Defined endurance specification — 2000 hours at 105 °C gives a measurable reliability baseline for thermal-stress planning.
