PLS0J391MCL2

The PLS0J391MCL2 is a conductive polymer aluminum solid electrolytic capacitor in a compact radial can. Engineered for long-life operation and low impedance, it delivers ultra-low ESR and high ripple-current capability for low-voltage, high-performance power applications.

With a rated capacitance of 390 µF at 6.3 V, a wide operating temperature range from −55°C to +105°C and a rated load life of 5000 hours at 105°C, this radial lead capacitor is suited to general-purpose designs that demand stable capacitance and reliable ripple handling in a small footprint.

Key Features

• Electrical Performance — 390 µF nominal capacitance at 6.3 V with ±20% tolerance; polarized device for low-voltage energy storage and decoupling.
• Ultra-low ESR — ESR specified as 15 mΩ at 100 kHz (20°C), reducing voltage ripple and improving transient response in power rails.
• High ripple-current capability — Rated ripple currents of 1.95 A at 120 Hz and 3.9 A at 100 kHz to support demanding AC conditions on low-voltage supplies.
• Long-life endurance — Load life: 5000 hours at 105°C with specified limits for capacitance change, tan δ and ESR after endurance testing.
• Thermal and environmental range — Operates from −55°C to +105°C with stable impedance characteristics across temperature extremes.
• Radial package and solder compatibility — Radial lead, can-style package (L: 7 × D: 8 mm) with 3.5 mm lead spacing; compatible with lead-free flow soldering conditions.
• Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose power filtering — Use where low ESR and high ripple handling improve power-supply smoothing and stability on 6.3 V rails.
• Embedded and portable electronics — Compact radial can and high ripple capability suit space-constrained modules requiring robust decoupling and energy buffering.
• Industrial control and instrumentation — Long life at elevated temperature (5000 h at 105°C) supports continuous operation in industrial environments within the specified temperature range.

Unique Advantages

• Low impedance at high frequency: 15 mΩ ESR at 100 kHz enables stronger transient suppression and improved regulator stability.
• High AC endurance: Ripple current ratings at both 120 Hz and 100 kHz allow reliable operation under AC-loaded power conditions.
• Extended high-temperature life: 5000 hours at 105°C provides predictable long-term performance where elevated operating temperatures are expected.
• Compact radial form factor: 7 × 8 mm can with 3.5 mm lead spacing delivers high capacitance density for board-level designs.
• Manufacturing-ready solder profile: Designed for lead-free flow soldering processes, facilitating modern assembly lines.
• Regulatory compliance: RoHS conformity supports use in regions requiring lead-free component selection.
