LLG2W331MELC30

The LLG2W331MELC30 is an aluminum electrolytic capacitor in a snap-in terminal, smaller-sized radial can package. It provides 330 µF of capacitance at a 450 V rating with polarized construction for general-purpose applications.

Designed for equipment downsizing, this component combines high-voltage bulk capacitance with a compact snap-in form factor, qualified for operation from −25 °C to +85 °C and compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Key Features

• Capacitance & Voltage — 330 µF rated capacitance at 450 V for high-voltage bulk energy storage in general-purpose designs.
• Smaller-sized Snap-in Package — Radial, can-type snap-in mounting in a smaller-sized case (one rank smaller than LLS) to support equipment downsizing and secure PCB attachment.
• Temperature & Lifetime — Rated for operation from −25 °C to +85 °C (for 400–450 V) with an endurance specification of 2000 hours at 85 °C under DC bias plus rated ripple current.
• Ripple Current Handling — Specified ripple performance of 1.95 A at 120 Hz and 2.788 A at 100 kHz to support common power filtering and smoothing loads.
• Electrical Characteristics — Capacitance tolerance ±20% (120 Hz, 20 °C); leakage current I ≤ 3√(C·V) μA after 5 minutes at 20 °C; tan δ max 0.20 at 450 V (120 Hz, 20 °C).
• Low-temperature Stability — Impedance ratio Z(−25 °C)/Z(+20 °C) up to 8 for 400–450 V ratings, maintaining performance in colder environments within the specified range.
• RoHS Compliance — Conforms to RoHS directive (2011/65/EU, (EU)2015/863).
• Physical Size — Compact dimensions L: 3 × D: 3.5 cm, suitable for constrained layouts where high-voltage capacitance is required.

Typical Applications

• General-purpose power equipment — Provides high-voltage bulk capacitance for smoothing and energy storage in a variety of general-purpose electronic and power systems.
• Equipment downsizing projects — Smaller-sized snap-in package supports reduced board footprint while maintaining 450 V capability.
• High-voltage filtering — Suitable for DC-link or high-voltage filter sections where polarized, high-capacitance components are required.

Unique Advantages

• High-voltage capability: 450 V rating gives designers the ability to use a single component for substantial DC bus voltages.
• Compact snap-in package: One-rank smaller case than the LLS series helps lower enclosure and PCB space requirements without sacrificing capacitance.
• Specified ripple performance: Rated ripple currents at both low and high frequency (1.95 A at 120 Hz, 2.788 A at 100 kHz) support real-world filtering demands.
• Endurance at elevated temperature: 2000 hours at 85 °C under rated conditions provides a clear reliability metric for thermal design and lifetime planning.
• Measured electrical limits: Leakage current formula and tan δ specification (max. 0.20 at 450 V) enable predictable loss and leakage budgeting in designs.
• RoHS compliant: Meets current RoHS requirements for environmental and regulatory consistency across regions.
