LLS2E391MELA

The LLS2E391MELA is an aluminum electrolytic capacitor in a snap‑in terminal package, rated at 390 µF and 250 V. It is designed as a general‑purpose capacitor offering measured ripple current capability and long endurance for a range of electronic assemblies.

Key attributes include snap‑in mounting, a φ25 × 30 mm radial can, RoHS compliance, and an operating temperature range of −40 °C to 85 °C with a rated lifetime of 3000 hours at 85 °C.

Key Features

• Capacitance and Voltage — 390 µF nominal capacitance with a 250 V rated voltage and ±20% tolerance at 120 Hz, 20 °C.
• Low Dissipation Factor — tan δ of 0.15 (max.) measured at 120 Hz and 20 °C, supporting efficient AC performance at rated conditions.
• Ripple Current Capability — 1.88 A at 120 Hz (low frequency) and 2.82 A at 50 kHz (high frequency) to handle AC stress within specified limits.
• Leakage Current — Typical leakage current specified at 930 µA after rated voltage application.
• Endurance — Rated to withstand 3000 hours at 85 °C with rated ripple current applied and the peak voltage not exceeding rated voltage.
• Temperature Range — Operational from −40 °C to +85 °C for 16 to 250 V ratings, consistent with the product’s rated voltage.
• Package & Mounting — Radial, can‑style snap‑in package (φ25 × 30 mm) supplied in trays for mass production assembly.
• Environmental Compliance — RoHS compliant.

Typical Applications

• General‑purpose electronic systems — Suitable where a 390 µF, 250 V snap‑in electrolytic capacitor is required for bulk energy storage and AC ripple handling in general designs.
• Industrial assemblies — Applicable to equipment that needs a robust snap‑in capacitor with a −40 °C to 85 °C operating range and long endurance at elevated temperature.
• OEM and production builds — Tray packing and snap‑in mounting simplify assembly into mass production workflows requiring consistent capacitor performance.

Unique Advantages

• Measured ripple performance — Specified ripple currents at both low and high frequency (1.88 A @120 Hz, 2.82 A @50 kHz) provide known AC handling limits for design validation.
• Extended endurance at elevated temperature — 3000 hours at 85 °C under rated ripple current enables designs that require sustained operation at higher ambient temperatures.
• Compact snap‑in can — φ25 × 30 mm radial snap‑in package offers a space‑efficient solution with secure mechanical mounting for assemblies.
• Low dissipation factor — tan δ of 0.15 at 120 Hz, 20 °C aids in minimizing AC losses within specified operating conditions.
• Regulatory compliance — RoHS compliance supports regulatory needs for many electronic products and supply chains.
