PLF1A470MDL4

The PLF1A470MDL4 is a conductive polymer aluminum solid electrolytic capacitor in a radial-lead can package. It delivers low ESR and high ripple-current capability in a compact form factor, designed for demanding power applications.

Targeted for automotive and power-conversion use, the device combines AEC‑Q200 qualification, RoHS compliance, lead‑free flow soldering compatibility and a wide operating temperature range to support robust, high-reliability designs.

Key Features

• Capacitance & Rated Voltage — 47 µF nominal capacitance with a 10 V rated voltage and ±20% tolerance for reliable energy storage in low-voltage systems.
• Low ESR — ESR of 25 mΩ measured at 100 kHz, minimizing losses and improving efficiency in high-frequency power circuits.
• High Ripple Current — 1.45 A at 120 Hz and 2.9 A at 100 kHz, enabling effective smoothing and decoupling under substantial AC stress.
• Thermal & Lifetime Performance — Operating range from −55°C to +105°C with a specified load life of 2000 hours at 105°C, supporting long-term operation in elevated-temperature environments.
• Package & Mounting — Radial lead, can-style package with 2.5 mm lead spacing and compact dimensions (L: 1.05 × D: 0.63 cm) for through-hole implementations.
• Reliability & Compliance — AEC‑Q200 qualified and RoHS compliant; compatible with lead‑free flow soldering conditions for automotive-grade manufacturing processes.
• Polarized Electrolyte — Polarized construction for conventional electrolytic capacitor uses; marked with navy-blue top print for polarity identification.

Typical Applications

• Automotive electronics — Suitable for automotive subsystems where AEC‑Q200 qualification, high ripple tolerance and extended temperature operation are required.
• Power-supply filtering — Low ESR and high ripple-current capability make this capacitor appropriate for smoothing and decoupling in DC‑DC converters and power rails.
• High-frequency power circuits — ESR specified at 100 kHz and a measured high-frequency ripple rating support use in circuits operating at elevated switching frequencies.

Unique Advantages

• Reduced conduction losses: Low ESR (25 mΩ at 100 kHz) lowers I²R losses and improves thermal performance in power circuits.
• Handles substantial ripple: Rated ripple currents of 1.45 A (120 Hz) and 2.9 A (100 kHz) support sustained AC stress and improved voltage stability.
• Automotive-capable reliability: AEC‑Q200 qualification and 2000 hours load life at 105°C provide traceable performance for demanding applications.
• Wide operating temperature: −55°C to +105°C specification maintains capacitance and ESR stability across typical automotive and industrial temperature ranges.
• Manufacturing-ready: Radial lead can with lead‑free flow soldering compatibility simplifies assembly into through-hole boards and mixed-technology production.
• Compact footprint: Small can dimensions and 2.5 mm lead spacing enable space-efficient placement in dense board layouts.
