LLG2W331MELB35

The LLG2W331MELB35 is an aluminum electrolytic capacitor from Nichicon's LLG series featuring a snap‑in terminal radial can. It provides 330 µF nominal capacitance at a 450 V rating and is designed for general‑purpose use.

Engineered to support equipment downsizing, this LLG series part offers a one‑rank smaller case size than the LLS series and is RoHS compliant. It targets designs that require high‑voltage capacitance in a compact snap‑in package with defined endurance and ripple performance.

Key Features

• Capacitance & Voltage — 330 µF rated capacitance at 450 V provides a high‑voltage option within the LLG family.
• Snap‑in Terminal, Radial Can — Snap‑in mounting offers secure board retention for chassis or PCB assemblies using radial can packaging.
• Compact Case Design — One rank smaller case size than LLS, suited for equipment downsizing where board space is constrained.
• Operating Temperature & Lifetime — Specified for operation from –25 °C to +85 °C with a rated endurance of 2000 hours at 85 °C under DC bias plus rated ripple current.
• Ripple Current Performance — Rated ripple currents include 1.95 A at 120 Hz and 2.788 A at 100 kHz, enabling defined AC loading within datasheet conditions.
• Leakage & Dielectric Loss — Leakage current specified as I ≤ 3√(C·V) µA (after 5 minutes at 20 °C); tangent of loss angle (tan δ) for 450 V is specified with a maximum of 0.20 at 120 Hz, 20 °C.
• Low‑Temperature Stability — Impedance ratio Z(–25 °C) / Z(+20 °C) is specified (max 8 for 450 V), providing documented behavior under low‑temperature conditions.
• Polarized, Tolerance — Polarized device with capacitance tolerance of −20% to +20% at 120 Hz, 20 °C.
• Environmental Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General Purpose — Intended for general‑purpose electronic designs that require a high‑voltage electrolytic capacitor in a snap‑in package.
• Equipment Downsizing — One rank smaller case size than LLS makes this part suitable for projects focused on reducing enclosure or board footprint.
• Radial Snap‑in Assemblies — Snap‑in radial can format supports secure mounting in assemblies that utilize through‑hole snap‑in capacitors.

Unique Advantages

• High‑Voltage Capability: 450 V rating allows designers to specify a single capacitor for higher DC voltage applications within the LLG series.
• Documented Endurance: 2000 hours at 85 °C endurance with post‑test limits (capacitance ±20%, tan δ ≤ 200% of initial, leakage ≤ initial) provides predictable life performance.
• Ripple Current Ratings: Specified ripple currents at 120 Hz and 100 kHz enable designers to assess AC loading and thermal considerations from the datasheet values.
• Predictable Leakage Behavior: Leakage defined by I ≤ 3√(C·V) µA (after 5 minutes at 20 °C) allows straightforward leakage budgeting in power designs.
• Compact Form Factor: Smaller case size than LLS helps reduce occupied volume while retaining snap‑in mounting convenience.
• RoHS Compliant: Meets RoHS directive requirements for environmentally conscious designs.
