LGM2W331MELB30

The LGM2W331MELB30 is an aluminum electrolytic capacitor in a snap‑in radial can designed for ultra‑smaller‑sized equipment. It provides 330 µF capacitance at a 450 V rating and is intended for general‑purpose applications where board‑level snap‑in mounting and reduced case size are important.

Designed for elevated operating temperatures up to 105 °C and compliant with RoHS (2011/65/EU, (EU)2015/863), this part targets compact power assemblies and applications requiring robust ripple handling and long‑term endurance in a reduced footprint.

Key Features

• Electrical Rating — 330 µF nominal capacitance with a 450 V rated voltage and ±20% capacitance tolerance at 120 Hz, 20 °C.
• High‑Temperature Operation — Rated for an operating temperature range of −25 °C to +105 °C to support elevated ambient environments.
• Endurance and Shelf Life — 2000 hours endurance at 105 °C under D.C. bias plus rated ripple current with limits on capacitance change (within ±20%), tan δ and leakage current; shelf life characteristics defined after 1000 hours at 105 °C.
• Ripple Current Capability — Rated ripple current of 730 mArms at 105 °C, 120 Hz; equivalent high‑frequency ripple handling up to approximately 1.044 A at 50 kHz (per frequency coefficient scaling).
• Low Leakage and Dielectric Loss — Leakage current specified as I ≤ 3√CV (μA) after five minutes at 20 °C; tangent of loss angle (tan δ) ≤ 0.20 at 120 Hz, 20 °C.
• Compact Snap‑In Package — Radial, snap‑in can packaging in a 30 × 30 mm footprint (L × D), one rank smaller case size than LGL series for equipment downsizing and denser board layouts.
• Polarized Design — Polarized capacitor suitable for DC applications that require a polarized electrolytic solution.
• RoHS Compliant — Conforms to RoHS directives (2011/65/EU, (EU)2015/863).
• Low‑Temperature Stability — Specified impedance stability with Z(−25 °C)/Z(+20 °C) ≤ 8 for maintained performance at lower temperatures.

Typical Applications

• Compact Power Supplies — Suited for equipment downsizing where a 450 V, 330 µF capacitor is needed for smoothing and ripple support in reduced footprints.
• General‑Purpose DC Filtering — Polarized snap‑in construction and defined leakage/tan δ make it suitable for general‑purpose DC filtering roles on power boards.
• High‑Temperature Environments — Operation up to 105 °C and 2000‑hour endurance make it suitable for assemblies exposed to elevated temperatures while retaining capacitance and dielectric characteristics.

Unique Advantages

• Smaller Case Size: One rank smaller than the LGL series, enabling more compact power designs and denser PCB layouts.
• High Voltage, High Capacitance: 450 V rating combined with 330 µF capacitance offers high energy density for DC link and filtering applications within a compact package.
• Robust Ripple Handling: 730 mArms rated ripple at 120 Hz and scaled high‑frequency capability (~1.044 A at 50 kHz) supports effective ripple suppression across frequencies.
• Temperature and Endurance Specified: Clear endurance and shelf‑life specifications at 105 °C (2000 h endurance, 1000 h shelf conditions) provide predictable long‑term behavior in demanding thermal conditions.
• Measured Leakage and Loss Limits: Leakage current formula (I ≤ 3√CV) and tan δ ≤ 0.20 give quantifiable electrical loss and leakage expectations for design validation.
• RoHS Compliance: Meets RoHS directives to support environmentally regulated product designs.
