LGU2W331MELB

The LGU2W331MELB is a snap‑in terminal aluminum electrolytic capacitor from Nichicon's LGU series, rated 330 µF at 450 V. It is a polarized, radial can snap‑in package designed for general‑purpose use where high voltage, elevated temperature endurance and reliable ripple handling are required.

This part is specified for operation from ‑25 °C to 105 °C and is designed to withstand 3000 hours of rated ripple current at 105 °C, providing predictable performance in demanding thermal environments.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with a 450 V rated voltage for high‑voltage general‑purpose designs.
• High‑temperature Endurance — Rated to operate up to 105 °C with a specified endurance of 3000 hours at 105 °C when subjected to DC bias plus rated ripple current.
• Ripple Current Performance — Specified ripple current: 1.45 A at 120 Hz and 2.074 A at 50 kHz, supporting sustained AC stress at both low and higher ripple frequencies.
• Mounting & Package — Snap‑in terminal, radial can (snap‑in) package for secure mechanical mounting and straightforward board installation.
• Polarized with Standard Tolerance — Polarized capacitor with capacitance tolerance of –20% to +20% (±20% at 120 Hz, 20 °C).
• Operating Temperature Range — Specified for –25 °C to +105 °C for the 315 to 450 V range.
• RoHS Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).
• Compact Form Factor — Physical size approximately L: 5 × D: 3 cm for integration into constrained power assemblies.

Typical Applications

• General‑purpose polarized capacitor needs — Suited for circuits that require a polarized snap‑in aluminum electrolytic capacitor rated at 330 µF and 450 V.
• High‑temperature environments — Used in equipment operating up to 105 °C where extended ripple endurance (3000 hours at 105 °C) is required.
• RoHS‑compliant designs — Appropriate for systems where RoHS compliance is required.

Unique Advantages

• Long high‑temperature endurance: 3000 hours at 105 °C under rated ripple conditions supports reliable long‑term operation in elevated temperatures.
• High voltage capability: 450 V rating enables use in higher‑voltage power applications without parallel capacitor arrangements.
• Measurable ripple handling: Specified ripple current values at 120 Hz and 50 kHz allow designers to validate thermal and ripple performance against system requirements.
• Practical snap‑in packaging: Radial, snap‑in can simplifies mechanical retention and board mounting for power assemblies.
• Regulatory conformity: RoHS compliance ensures alignment with common environmental requirements.
• Clear specification set: Polarized construction, ±20% capacitance tolerance, and defined operating temperature range make selection and qualification straightforward.
