PCM1E271MCL1GS

The PCM1E271MCL1GS is a conductive polymer aluminum solid electrolytic, chip‑type capacitor designed for surface‑mount integration. It provides 270 µF at 25 V with polarized construction and a compact SMD can package (L: 1.2 × D: 0.8 cm).

Engineered for applications that demand low ESR, high ripple handling and extended operation in elevated temperatures, this part is qualified to AEC‑Q200 and is RoHS compliant, making it suitable for automotive and other high‑temperature electronics environments.

Key Features

• Capacitance & Voltage — 270 µF rated capacitance at 25 V with ±20% tolerance (measured at 120 Hz, 20°C), suitable for bulk decoupling and energy storage in power rails.
• Low ESR & High Ripple Capability — 19 mΩ ESR at 100 kHz and ripple current ratings of 2.8 A (100 kHz) and 1.4 A (120 Hz), enabling effective smoothing and transient handling in high-frequency power stages.
• High Temperature Operation — Rated operating temperature range of −55°C to +125°C with a specified endurance of 8000 hours at 125°C, supporting sustained performance in hot environments.
• Reliability & Qualification — AEC‑Q200 qualified and designed for long life and stability after endurance and damp‑heat tests; leakage current and ESR specifications are maintained after required stress conditions.
• Surface-Mount Package — Chip-type SMD can (radial, can - SMD) with recommended land size L: 8.3 × W: 8.3 mm; compatible with lead‑free reflow soldering up to a 260°C peak.
• Compliance — RoHS compliant, meeting lead‑free and restricted substance requirements listed in the product data.

Typical Applications

• Automotive Electronics — Suitable for use in vehicle electronic control units and onboard power systems where AEC‑Q200 qualification and high‑temperature endurance are required.
• Power Supply Decoupling — Bulk decoupling and smoothing in DC‑DC converters and power rails, leveraging low ESR and high ripple current capability.
• High‑Temperature Power Modules — Energy storage and filtering in power assemblies that operate continuously at elevated temperatures up to 125°C.

Unique Advantages

• Low ESR for high-efficiency filtering: 19 mΩ at 100 kHz reduces losses and improves transient response in switching power stages.
• High ripple current tolerance: 2.8 A (100 kHz) and 1.4 A (120 Hz) ripple ratings support demanding, high-frequency power applications.
• Extended high-temperature life: 8000 hours at 125°C endurance provides predictable long-term performance in hot environments.
• AEC‑Q200 qualified: Designed to meet automotive grade reliability requirements for qualified electronics applications.
• Surface-mount, reflow-capable: SMD can package compatible with lead‑free reflow up to 260°C peak for modern assembly processes.
• RoHS compliant: Aligns with regulatory requirements for restricted substances and lead‑free manufacturing.
