PLF0G391MDL4

The PLF0G391MDL4 from Nichicon 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 through-hole form factor, with a rated capacitance of 390 µF at 4 V and polarization for DC applications.

Engineered for temperature-critical environments, the capacitor offers a rated operating range of −55°C to +105°C and a specified load life of 2000 hours at 105°C. The part is RoHS compliant and AEC-Q200 qualified. Note: this product is scheduled for discontinuation and is not recommended for new designs.

Key Features

• Conductive polymer construction — Solid electrolyte design provides low equivalent series resistance for efficient power delivery.
• Low ESR — ESR specified at 24 mΩ (measured at 100 kHz, 20°C), supporting stable decoupling and supply smoothing.
• High ripple-current capability — Rated ripple current of 1.65 A at 120 Hz and 3.3 A at 100 kHz to handle dynamic load currents.
• Robust thermal endurance — Load life specified as 2000 hours at 105°C; endurance and damp-heat characteristics defined in the datasheet.
• Automotive-grade qualification — AEC-Q200 qualified and listed for automotive applications.
• Radial lead, through‑hole package — Compact can package with lead spacing of 2.5 mm and physical size L: 1.05 × D: 0.63 cm, compatible with lead-free flow soldering conditions.
• Wide operating temperature — Specified from −55°C to +105°C for broad environmental tolerance.

Typical Applications

• Automotive control modules — Local power decoupling and smoothing on ECUs and sensor interface boards where AEC-Q200 qualification and high ripple handling are required.
• Power supply filtering — Bulk and output filtering in low-voltage DC power rails that benefit from low ESR and compact radial packaging.
• Embedded and industrial electronics — Supply stabilization and transient suppression in compact through‑hole assemblies operating across wide temperature ranges.

Unique Advantages

• Low ESR for improved voltage stability: 24 mΩ ESR at 100 kHz reduces ripple voltage and improves converter performance.
• High ripple-current tolerance: 1.65 A (120 Hz) and 3.3 A (100 kHz) ratings support dynamic loads and heavy switching environments.
• High-temperature endurance: 2000 hours at 105°C provides predictable long-term performance in elevated-temperature applications.
• Automotive qualification: AEC-Q200 rating signals suitability for automotive hardware where that qualification is required.
• Compact radial can package: 2.5 mm lead spacing and a 1.05 × 0.63 cm footprint enable space-efficient through-hole designs and lead-free flow solder compatibility.
• RoHS compliant: Meets current RoHS directives for restricted substances.
