PCA1E271MCL1GS

The PCA1E271MCL1GS is a chip-type conductive polymer aluminum solid electrolytic capacitor designed for high-reliability surface-mount applications. It delivers 270 µF at 25 V in a compact package (L: 1.2 × D: 0.8 cm) and combines low ESR with high ripple-current capability to support demanding power circuits.

Engineered for extended operation in elevated temperatures and qualified to AEC‑Q200, this part targets automotive and other high-reliability electronics where long life, thermal endurance, and robust solder-process compatibility are required.

Key Features

• Conductive polymer aluminum construction — Solid electrolyte design for improved ripple handling and stable electrical performance compared to wet electrolytic types.
• High capacitance in a compact SMD can — 270 µF rated capacitance at 25 V supplied in a chip-style radial can (SMD), size L: 1.2 × D: 0.8 cm.
• Low ESR and high ripple current — ESR of 19 mΩ measured at 100 kHz and rated ripple current up to 4 A at 100 kHz (2 A at 120 Hz) for effective smoothing and decoupling under high AC stress.
• Extended high-temperature life — Rated for 4000 hours at 125°C and specified operating range from −55°C to +125°C, supporting long-term performance in elevated-temperature environments.
• AEC‑Q200 qualified — Meets AEC‑Q200 requirements for high-reliability applications.
• Reflow-capable SMD — Designed for lead‑free reflow soldering with a 260°C peak profile; recommended surface-mount land size 8.3 × 8.3 mm.
• RoHS compliant — Conforms to the RoHS directive (2011/65/EU, (EU)2015/863).
• Polarized can-style package — Radial, can‑style SMD with clear polarity for straightforward placement in power circuits.

Typical Applications

• Automotive electronics — Bulk and decoupling capacitor for power rails, ECUs, and other vehicle electronics that require AEC‑Q200 qualification and extended thermal endurance.
• Power management and DC‑DC converters — Low ESR and high ripple-current capability make it suitable for output filtering and energy smoothing in high-current converter stages.
• High-reliability embedded systems — Long life at elevated temperature and controlled leakage specifications support designs where predictable endurance is required.

Unique Advantages

• Superior ripple handling: 4 A at 100 kHz and 2 A at 120 Hz ripple-current ratings reduce thermal stress and voltage ripple on power rails.
• Low ESR for better transient response: 19 mΩ ESR at 100 kHz helps minimize voltage drop and improve regulator stability.
• Long high-temperature endurance: 4000 hours at 125°C provides predictable life in elevated-temperature applications.
• AEC‑Q200 reliability: Qualification to AEC‑Q200 supports use in automotive-grade designs requiring rigorous component-level reliability.
• Reflow compatibility: Designed for lead-free reflow to 260°C peak, enabling standard SMD assembly processes without special handling.
• RoHS compliance: Meets modern environmental requirements for electronics manufacturing.
