PLF1D470MCL2

The PLF1D470MCL2 is a conductive polymer aluminum solid electrolytic capacitor in a radial lead, can-style package. It delivers low equivalent series resistance (ESR) and high ripple current capability in a compact through-hole form factor for demanding electronics assemblies.

Key attributes include 47 µF capacitance at 20 V, AEC-Q200 qualification, RoHS compliance, lead-free flow soldering compatibility, and a load life of 2000 hours at 105°C. Note: this product is scheduled to be discontinued and is not recommended for new designs.

Key Features

• Capacitance & Voltage — 47 µF rated capacitance with a 20 V rated voltage provides energy storage and decoupling for mid-voltage circuits.
• Low ESR — ESR specified at 45 mΩ measured at 100 kHz (20°C), enabling lower loss and improved thermal performance in high-current conditions.
• High Ripple Current — Ripple current ratings of 1 A at 120 Hz and 2 A at 100 kHz support both low- and high-frequency power filtering needs.
• Thermal Endurance — Load life of 2000 hours at 105°C and an operating temperature range of −55°C to +105°C for sustained performance under elevated temperatures.
• Package & Mounting — Radial lead can package with lead spacing of 3.5 mm and physical dimension L: 7 × D: 8 mm for through-hole assemblies.
• Reliability & Compliance — AEC-Q200 qualified and RoHS compliant; designed for automotive-grade reliability and lead-free flow soldering conditions.
• Polarized Design — Polarized capacitor suitable where polarity is defined and maintained in the circuit.
• Tolerance — Capacitance tolerance of −20% to +20% at 120 Hz, 20°C.

Typical Applications

• Automotive electronics — Suited for AEC-Q200-qualified systems where low ESR and high ripple current are required.
• Through-hole power assemblies — Radial lead package fits legacy and repair applications using can-style through-hole mounting.
• High-frequency power circuits — Ripple performance specified up to 100 kHz supports filtering in high-frequency power stages.

Unique Advantages

• Low-loss operation: The 45 mΩ ESR at 100 kHz reduces power dissipation and heating in high-current applications.
• High ripple handling: Rated ripple current of 2 A at 100 kHz enables effective smoothing in high-frequency environments.
• High-temperature endurance: 2000 hours load life at 105°C supports prolonged operation in elevated-temperature applications.
• Automotive-grade qualification: AEC-Q200 qualification provides a documented baseline for use in automotive assemblies.
• Lead-free solder compatibility: Designed to meet lead-free flow soldering conditions for modern assembly processes.
• Compact through-hole form: Small L: 7 × D: 8 mm can with 3.5 mm lead spacing makes the capacitor suitable for space-constrained through-hole layouts.

Why Choose PLF1D470MCL2?

PLF1D470MCL2 combines conductive polymer low-ESR performance with high ripple handling and validated high-temperature endurance, making it a practical choice where robust power decoupling and thermal reliability are required. Its AEC-Q200 qualification and lead-free soldering compatibility align with automotive-grade manufacturing and assembly processes.

Because this part is scheduled for discontinuation and is not recommended for new designs, it is most appropriate for sustaining existing designs or for applications where the specified combination of size, ESR, ripple current, and thermal life directly matches requirements.
