PLF1D390MCL2

The PLF1D390MCL2 from Nichicon is a conductive polymer aluminum solid electrolytic capacitor in a radial lead can package. Designed for demanding power applications, it delivers low equivalent series resistance (ESR) and high ripple-current capability in a compact form.

Engineered for automotive and industrial environments, this 39 μF, 20 V polarized capacitor provides a wide operating temperature range of -55°C to 105°C and a rated load life of 2000 hours at 105°C. It is AEC-Q200 qualified and RoHS compliant.

Key Features

• Capacitance & Voltage — 39 μF rated capacitance at 20 V for bulk decoupling and smoothing in low-voltage power rails.
• Low ESR — 45 mΩ ESR specified at 100 kHz, supporting high-frequency decoupling and improved power-supply stability.
• High Ripple Current — 1 A at 120 Hz and 2 A at 100 kHz, enabling reliable handling of AC ripple and switching currents.
• Thermal and Endurance Performance — Operating range of -55°C to +105°C with a load life of 2000 hours at 105°C for long-term thermal reliability.
• Packaging & Mounting — Radial lead, can-style package with 3.5 mm lead spacing and compact dimensions (L: 7 × D: 8 mm) for through-hole assemblies.
• Quality & Compliance — AEC-Q200 qualified and RoHS compliant (2011/65/EU,(EU)2015/863) for regulated environments.
• Polarized Electrolyte — Conductive polymer aluminum solid electrolyte; polarity must be observed in circuit implementation.

Typical Applications

• Automotive power modules — Use on low-voltage vehicle power rails and control modules where low ESR and high ripple handling improve stability.
• DC–DC converter output filtering — Compact radial can provides bulk capacitance and supports switching converter ripple currents.
• Industrial power electronics — Suitable for control boards and power supplies that require robust temperature endurance and high ripple capability.

Unique Advantages

• Low ESR for improved transient response: 45 mΩ at 100 kHz reduces voltage ripple and supports tighter regulation in switching supplies.
• High ripple-current capacity: Rated 1 A (120 Hz) and 2 A (100 kHz) to endure heavy AC stress from power converters and inrush events.
• Compact, board-friendly package: Radial lead can with 3.5 mm lead spacing and small L×D footprint simplifies through-hole assembly in space-constrained designs.
• Designed for elevated temperatures: -55°C to +105°C operation and 2000-hour life at 105°C support sustained performance in hot operating environments.
• Automotive-grade qualification: AEC-Q200 rating provides an added level of component qualification for automotive and similarly demanding applications.
• Regulatory compliance: RoHS-compliant construction meets environmental regulatory requirements.
