PCV1V181MCL2GS

The PCV1V181MCL2GS is a surface-mount conductive polymer aluminum electrolytic capacitor in Nichicon’s PCV series, specified at 180 µF and 35 V. It combines low equivalent series resistance and high ripple current capability with a compact SMD can package designed for demanding environments.

Engineered for automotive and other harsh-environment electronics, the part offers a rated operating range of −55 °C to +105 °C, a 3000‑hour load life at 105 °C, RoHS compliance, and AEC‑Q200 qualification for reliability-conscious designs.

Key Features

• Capacitance & Voltage: 180 µF nominal capacitance with a 35 V rated voltage and ±20% tolerance at 120 Hz, 20 °C.
• Low ESR: 22 mΩ equivalent series resistance measured at 100 kHz, supporting efficient energy transfer and reduced loss.
• High Ripple Current: Rated ripple current of 4.1 A at 100 kHz and 2.05 A at 120 Hz to handle high-frequency and low-frequency ripple on power rails.
• Long Life & Temperature Range: Load life of 3000 hours at 105 °C and an operating temperature range of −55 °C to +105 °C for extended reliability in elevated-temperature applications.
• SMD Can Package: Radial, can-style SMD package with overall dimensions L: 1.27 × D: 1.00 cm and recommended land size L: 1.03 × W: 1.03 cm for compact board-level integration.
• Assembly Compatibility: Lead‑free reflow soldering capable with a 260 °C peak correspondence, meeting surface-mount process requirements.
• Automotive-Grade Qualification: AEC‑Q200 qualified and RoHS compliant for use in regulated and safety-conscious systems.
• Polarized Design: Polar capacitor construction for correct orientation in DC power circuits.

Typical Applications

• Automotive power electronics: Use in in-vehicle power systems where long life at elevated temperature and AEC‑Q200 qualification are required.
• DC–DC converter outputs: Supports output smoothing and ripple handling thanks to low ESR (22 mΩ) and high ripple current ratings.
• Harsh-environment electronic modules: Suited to modules that require wide temperature operation (−55 °C to +105 °C) and a verified 3000-hour endurance at 105 °C.

Unique Advantages

• Low-loss operation: 22 mΩ ESR at 100 kHz minimizes power dissipation and improves converter efficiency under high-frequency switching.
• Robust ripple handling: 4.1 A ripple current at 100 kHz and 2.05 A at 120 Hz allow the capacitor to manage both high-frequency switching noise and lower-frequency ripple.
• Long-term thermal endurance: 3000‑hour load life at 105 °C provides predictable end-of-life behavior for long-life product platforms.
• Automotive-grade reliability: AEC‑Q200 qualification and RoHS compliance support deployment in regulated automotive electronics and related applications.
• SMD form factor: Compact radial can SMD package with defined land size simplifies board layout and saves PCB space compared with larger through-hole options.
• Assembly-ready: Compatible with lead‑free reflow processes up to a 260 °C peak, enabling modern surface-mount manufacturing flows.
