PCL1A471MCL1GS

The PCL1A471MCL1GS is a conductive polymer aluminum solid electrolytic chip capacitor designed for surface-mount applications. It combines high capacitance (470 µF) with low ESR and high ripple-current capability to support robust power-filtering and decoupling in demanding environments.

Targeted at automotive and other high-reliability markets, this SMD capacitor delivers long-term stability with a rated lifetime of 20000 hours at 105°C, AEC-Q200 qualification, and lead-free reflow soldering compatibility up to a 260°C peak.

Key Features

• Dielectric / Construction Conductive polymer aluminum solid electrolytic construction for stable capacitance and improved ESR compared with conventional electrolytics.
• Capacitance & Voltage 470 µF capacitance at a 10 V rated voltage with ±20% tolerance for bulk energy storage and smoothing.
• Low ESR & High Ripple Current ESR of 17 mΩ (measured at 100 kHz) and ripple current ratings of 1.9 A (120 Hz) and 3.8 A (100 kHz) to minimize losses and heat under dynamic loads.
• Extended High‑Temperature Lifetime Endurance specified at 20000 hours when operated at 105°C, supporting long-term reliability in elevated-temperature applications.
• Temperature Range & Stability Operates from −55°C to +105°C; impedance ratios specified to maintain performance across the temperature range.
• Surface-Mount Package Chip-type radial can SMD package with compact dimensions (L: 1 cm × D: 0.8 cm) and a recommended land size of 8.3 × 8.3 mm for PCB layout.
• Manufacturing Compatibility & Compliance Compatible with lead-free reflow soldering (260°C peak, single pass at 260°C max), RoHS compliant, and AEC-Q200 qualified.

Typical Applications

• Automotive power electronics — Bulk filtering and smoothing where long life at elevated temperature and AEC‑Q200 qualification are required.
• DC–DC converter outputs — High capacitance and low ESR reduce output ripple and improve regulator stability under load transients.
• On-board power rails — Decoupling and energy storage for microcontrollers, FPGAs, and other power-sensitive modules operating across −55°C to +105°C.

Unique Advantages

• Long high-temperature endurance: 20000 hours at 105°C provides predictable service life in harsh thermal environments.
• Low ESR for efficiency: 17 mΩ at 100 kHz reduces I²R losses and helps control self-heating in high-current applications.
• High ripple-current capability: Rated for 1.9 A (120 Hz) and 3.8 A (100 kHz) to handle dynamic and high-frequency load conditions.
• AEC‑Q200 qualified: Suited for designs that require automotive-grade component qualification and traceable reliability data.
• Surface-mount, reflow compatible: Chip-type SMD construction and single-pass 260°C reflow compatibility simplify automated assembly and process flows.
• RoHS compliant: Meets current RoHS requirements for lead-free designs.
