RPS1C181MCN1GS

The RPS1C181MCN1GS is a surface-mount conductive polymer aluminum solid electrolytic capacitor from Nichicon’s RPS series. It delivers 180 µF capacitance at a 16 V rating with low ESR and robust ripple-current handling for general-purpose power applications.

Designed for compact SMD assemblies, this φ8×11.7 mm radial can offers a wide operating temperature range of −55 °C to 105 °C and a specified endurance of 2000 hours at 105 °C, providing reliable performance in demanding environments.

Key Features

• Dielectric / Core Conductive polymer solid electrolyte construction for stable electrical performance and reduced equivalent series resistance compared with traditional electrolytes.
• Capacitance & Tolerance 180 µF nominal capacitance with tolerance −20% to +20% (measured at 20 °C, 120 Hz).
• Voltage Rating Rated at 16 V DC.
• Low Dissipation Factor tanδ = 0.12 (measured at 20 °C, 120 Hz), supporting efficient AC performance.
• Low ESR ESR = 20 mΩ (at 20 °C / 100 kHz), enabling effective high-frequency filtering and reduced losses.
• High Ripple Current Low-frequency ripple current: 370 mA at 120 Hz; high-frequency ripple current: 3.7 A at 300 kHz (frequency coefficients per datasheet apply).
• Leakage Current Specified leakage current of 576 µA (after 2 minutes at 20 °C).
• Reliability Load-life rating: 2000 hours at 105 °C (capacitance, tanδ and ESR limits per datasheet endurance criteria).
• Package & Mounting Surface-mount radial can, case size φ8 × 11.7 mm, recommended land size 8.3 × 8.3 mm; supplied in embossed carrier taping with moisture-proof packing.
• Environmental Compliance RoHS compliant.

Typical Applications

• Power supply output filtering — Low ESR (20 mΩ) and 3.7 A high-frequency ripple capability make this part suitable for smoothing outputs of DC–DC converters and switching regulators.
• Decoupling in high-frequency circuits — tanδ = 0.12 at 120 Hz and conductive polymer construction support stable decoupling where low-loss, compact capacitance is needed.
• Embedded and industrial electronics — Wide operating range (−55 °C to 105 °C) and 2000 h endurance at 105 °C provide robustness for industrial and long-life applications.
• Power modules and board-level energy storage — 180 µF capacitance in a compact φ8×11.7 mm SMD can supports transient response and energy buffering in compact power assemblies.

Unique Advantages

• High ripple-current capability: 3.7 A at 300 kHz enables handling of high-frequency switching peaks without excessive heating.
• Very low ESR: 20 mΩ at 100 kHz reduces power loss and improves converter efficiency and thermal performance.
• Compact SMD radial can: φ8×11.7 mm delivers substantial capacitance in a small footprint with recommended land size provided for PCB layout.
• Wide temperature tolerance and defined endurance: −55 °C to 105 °C operating range and 2000 hours at 105 °C support sustained operation in elevated-temperature environments.
• Lead-free reflow compatibility: RPS series SMD types correspond to lead-free reflow peak conditions (per datasheet), simplifying assembly process qualification.
• RoHS compliant packaging: Supplied in embossed carrier taping with moisture-proof packing for automated SMT lines and moisture-sensitive component handling.
