PCF1A271MCL4GS

The PCF1A271MCL4GS is a conductive polymer aluminum solid electrolytic capacitor in a surface-mount radial can package, offering 270 µF capacitance at a 10 V rating. Designed for applications that demand low equivalent series resistance and high ripple-current capability, it is positioned for automotive and other demanding power-electronic environments.

Key value points include low ESR (13 mΩ at 20°C/100 kHz), high ripple-current handling (2.25 A at 120 Hz and 4.5 A at 100 kHz), and a 2000-hour endurance at 105°C—providing stability and durability for sustained high-temperature operation.

Key Features

• Capacitance and Voltage — 270 µF capacitance with a 10 V rated voltage and tolerance of -20% to 20% for predictable bulk energy storage and decoupling.
• Low ESR and High Ripple Capability — ESR of 13 mΩ measured at 20°C/100 kHz, with low-frequency ripple current of 2.25 A (120 Hz) and high-frequency ripple current of 4.5 A (100 kHz) to support high-current transient and switching applications.
• Thermal and Endurance Performance — Operational temperature range from -55°C to +105°C and load life rated to 2000 hours at 105°C for extended high-temperature service.
• Electrical Loss — Tangent of loss angle (tan δ) specified at 0.12 (measured at 20°C, 120 Hz) to characterize dielectric losses under typical test conditions.
• Leakage and Reliability — Leakage current specified at 540 µA (after rated voltage application), with endurance and damp-heat characteristics defined by the PCF series qualification tests.
• Package and Mounting — Surface-mount radial can (φ8 × 12L; L: 1.2 × D: 0.8 cm) with recommended land pattern 8.3 × 8.3 mm; shipped in embossed carrier taping with moisture-proof packing for automated assembly.
• Manufacturing and Compliance — AEC-Q200 qualified and RoHS compliant; compatible with lead-free reflow soldering up to the series-specified profiles (peak 260°C single reflow, ≤250°C for up to two reflows) per the PCF series datasheet.

Typical Applications

• Automotive Electronics — Suited for automotive power rails and modules where low ESR and high ripple-current handling are required under elevated temperatures.
• Power Conversion — Useful in power-supply output filtering and bulk decoupling for systems that need stable capacitance and low loss at switching frequencies.
• High-Temperature Systems — Applied in modules exposed to sustained high temperatures due to its 2000-hour life rating at 105°C and wide operating temperature range.

Unique Advantages

• High Ripple-Current Endurance: Rated for 2.25 A at 120 Hz and 4.5 A at 100 kHz, enabling reliable handling of both low- and high-frequency ripple currents.
• Very Low ESR: 13 mΩ (20°C/100 kHz) reduces dissipation and improves voltage stability under load.
• Automotive-Grade Qualification: AEC-Q200 qualification supports use in automotive applications with defined reliability expectations.
• Elevated Temperature Durability: 2000 hours life at 105°C provides a defined endurance metric for long-term deployment in heated environments.
• Assembly-Ready Packaging: Embossed carrier taping and moisture-proof packing streamline automated SMD placement and storage.
• Lead-Free Reflow Compatibility: Conforms to the PCF series reflow profiles (up to 260°C peak per datasheet), facilitating lead‑free manufacturing processes.
