PCA1V331MCL1GS

The PCA1V331MCL1GS is a chip-type conductive polymer aluminum solid electrolytic capacitor engineered for high-reliability power applications. It combines low ESR and high ripple current capability with a long-rated life of 4000 hours at 125°C, making it suitable for demanding environments including automotive electronics.

This surface-mount, polarized can package is designed for lead-free reflow soldering (260°C peak) and complies with RoHS and AEC-Q200 requirements for reliable operation across a −55°C to +125°C temperature range.

Key Features

• Capacitance & Voltage: 330 µF capacitance rated at 35 V with ±20% tolerance (120 Hz, 20°C).
• Low ESR: ESR of 16 mΩ measured at 100 kHz, supporting efficient power delivery and reduced loss.
• High Ripple Current: Handles 2.5 A at 120 Hz and 5 A at 100 kHz, enabling robust smoothing and decoupling in high-current circuits.
• High-Temperature Endurance: Qualified for 4000 hours at 125°C under rated DC bias plus ripple current; meets specified endurance criteria for capacitance, ESR and leakage.
• Wide Operating Temperature: Rated for −55°C to +125°C, maintaining impedance stability across the specified range.
• SMD Radial Can with Reflow Compatibility: Chip-type surface-mount radial can designed for lead-free reflow; peak soldering temperature up to 260°C (reflow 2 times maximum under specified profile).
• Reliability & Compliance: AEC-Q200 compliant and RoHS directive (2011/65/EU,(EU)2015/863) compatible for regulated environments.
• Package Size: Compact footprint with body dimensions L: 1.27 × D: 1.00 cm and recommended land size L: 1.03 × W: 1.03 cm for PCB layout.

Typical Applications

• Automotive power electronics: Filtering and decoupling on ECU power rails and DC‑DC converters where AEC-Q200 compliance and high-temperature endurance are required.
• DC‑DC converters and voltage regulators: Bulk and output smoothing to support high ripple currents and low ESR requirements in compact power modules.
• Motor drive and actuator control: Energy buffering and ripple suppression in systems exposed to elevated temperatures and transient currents.
• Industrial power supplies: Robust filtering for power management in harsh or high-temperature industrial environments.

Unique Advantages

• Designed for high-ripple environments: Rated ripple current (5 A at 100 kHz) combined with low ESR (16 mΩ) reduces heating and improves reliability under heavy AC stress.
• Long high-temperature life: 4000 hours at 125°C endurance rating provides predictable lifetime behavior for high-temperature designs.
• Reflow-friendly SMD can: Compatible with lead-free reflow processes up to 260°C peak, enabling modern assembly flows without special handling.
• AEC-Q200 qualification: Explicit AEC-Q200 compliance supports use in automotive and other safety-conscious market segments requiring component-level qualification.
• Compact footprint: Small L × D dimensions and defined land pattern ease PCB layout in space-constrained power assemblies.
• Regulatory compliance: RoHS compliant to relevant directives for use in regulated products and regions.
