PCX1V390MCL6GS

The PCX1V390MCL6GS is a conductive polymer aluminum solid electrolytic chip capacitor in an SMD can package. It combines a 39 µF capacitance with a 35 V rating and a polarized design for compact, high-voltage applications.

Designed for demanding environments, this device delivers low ESR and high ripple-current capability with long-term endurance at elevated temperatures, making it suitable for automotive and industrial power electronics where reliability and thermal robustness are required.

Key Features

• Electrical performance — 39 µF nominal capacitance with a 35 V rated voltage and ±20% tolerance, providing predictable energy storage and decoupling in power rails.
• Low ESR — 35 mΩ equivalent series resistance measured at 100 kHz, helping reduce power loss and heat generation in high-frequency circuits.
• High ripple-current capability — Rated ripple currents of 350 mA at 120 Hz and 700 mA at 100 kHz, enabling effective smoothing and decoupling in switching power supplies.
• Long-life, high-temperature endurance — Specified lifetime of 3000 hours at 125°C and endurance performance outlined in the datasheet for sustained reliability under thermal stress.
• Surface-mount can package — Radial can SMD package with compact footprint (L: 1.0 × D: 0.8 cm) and recommended land size 8.3 × 8.3 mm for board-level integration.
• Assembly-ready — Compatible with lead-free reflow soldering up to a 260°C peak, supporting modern Pb-free manufacturing processes.
• Quality and compliance — AEC-Q200 qualified and RoHS compliant, addressing industry quality expectations and environmental requirements.

Typical Applications

• Automotive power modules — Bulk decoupling and smoothing in automotive electronics where AEC-Q200 qualification and high-temperature endurance are required.
• Switch-mode power supplies (SMPS) — Input/output filtering and ripple suppression in DC‑DC converters that demand low ESR and high ripple-current handling.
• Industrial control electronics — Energy storage and transient suppression in controllers and power subsystems operating over −55°C to +125°C.
• Compact SMD assemblies — Board-level decoupling and bypass in space-constrained surface-mount designs benefiting from a can-type SMD footprint and reflow compatibility.

Unique Advantages

• High ripple handling: 700 mA at 100 kHz supports aggressive switching applications and reduces the need for oversized capacitors.
• Low-loss operation: 35 mΩ ESR at 100 kHz minimizes dissipation and improves thermal performance in high-frequency circuits.
• Extended high-temperature life: 3000 hours at 125°C provides long-term stability in thermally demanding environments.
• AEC-Q200 qualification: Meets automotive-grade reliability criteria for customers targeting vehicle electronics.
• Reflow-ready SMD can: Lead-free reflow compatibility to 260°C simplifies integration into modern SMT production flows.
• Compact footprint: Small L × D dimensions and defined land pattern enable high-density PCB designs.
