LLS2W331MELC

The LLS2W331MELC is a snap-in terminal aluminum electrolytic capacitor from Nichicon's LLS series, rated at 330 µF and 450 V. It is a radial, can-style, polarized capacitor designed for general-purpose applications requiring high-voltage bulk capacitance and robust ripple handling.

Engineered for durability, this capacitor is specified to withstand 3000 hours of application of rated ripple current at 85°C and is RoHS compliant (2011/65/EU, (EU)2015/863), making it suitable for designs that demand consistent performance under sustained load.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with a 450 V rated voltage and a tolerance of −20% to +20%, providing defined high-voltage bulk storage.
• Endurance under Ripple — Specified to withstand 3000 hours of rated ripple current at 85°C; series endurance criteria include capacitance change within ±20% and leakage current remaining at or below the initial specified value after the test.
• Ripple Current Performance — Measured ripple current capabilities include 2.15 A at 120 Hz and 3.075 A at 50 kHz, enabling reliable filtering and energy-smoothing in high-voltage circuits.
• Operating Temperature — Rated for operation from −25°C to +85°C for the 350 to 450 V range, matching the thermal requirements for many industrial and commercial power applications.
• Mounting & Package — Snap-in radial can package for secure chassis or board mounting; physical size is L: 3.5 × D: 3.5 cm with a maximum seated height of 1.378 inches.
• Leakage and Dissipation Characteristics — Meets series leakage current and tangent-of-loss-angle (tan δ) specifications from the LLS datasheet; leakage current is specified as I ≤ 3√CV (µA) after 5 minutes at 20°C for the series.
• Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose high-voltage power assemblies — Bulk energy storage and smoothing where a polarized, high-voltage capacitor is required.
• Industrial power supplies — Filtering and ripple attenuation in 350–450 V systems consistent with the LLS series' rated temperature range and ripple endurance.
• Commercial electronic equipment — High-voltage decoupling and energy buffering for general-purpose designs that require snap-in mounting and long-term ripple performance.

Unique Advantages

• High-voltage capability: 450 V rating provides substantial headroom for 350–450 V applications.
• Demonstrated ripple endurance: 3000-hour rated ripple-current endurance at 85°C ensures stability in sustained-loading environments.
• Measured ripple-current specs: Published ripple current values at 120 Hz and 50 kHz allow designers to size capacitors against expected AC stress.
• Snap-in radial package: Robust mechanical retention for chassis or board installation and simplified assembly.
• RoHS compliance: Meets current RoHS requirements for restricted substances.
• Clear performance criteria: Endurance and shelf-life limits (capacitance change, tan δ, leakage current) are defined in the LLS series datasheet for predictable lifetime behavior.
