LGU2Z331MELY

The LGU2Z331MELY from Nichicon is a 330 µF, 180 V snap-in aluminum electrolytic capacitor in the LGU series. It is a polarized, radial snap‑in terminal type designed for general‑purpose applications that require bulk capacitance, sustained ripple handling and elevated temperature endurance.

Key value propositions include a 105°C operating range with a demonstrated 3000 hours endurance under rated ripple current, industry‑relevant ripple current capability at both low and high frequencies, and RoHS compliance for environmental conformance.

Key Features

• Electrical Performance — 330 µF capacitance at 180 V rated voltage with ±20% tolerance and a tangent of loss angle (tanδ) of 0.15 measured at 20°C, 120 Hz.
• Ripple Current Capability — Low‑frequency ripple current of 1.2 A (120 Hz) and high‑frequency ripple current of 1.8 A (50 kHz), enabling effective smoothing across a range of operating frequencies.
• Endurance at Elevated Temperature — Designed to withstand 3000 hours of rated ripple current at 105°C per LGU series specifications.
• Leakage and Reliability — Specified leakage current of 730 µA and endurance limits that maintain capacitance within ±20% after the life test.
• Mechanical & Mounting — Snap‑in terminal, radial can package (φ20 × 30 mm), supplied in tray packing for board assembly and handling.
• Environmental Compliance — RoHS compliant and available in mass production.
• Voltage Category Frequency Coefficients (160–250 V) — Frequency coefficients for rated ripple current: 50 Hz: 0.81, 60 Hz: 0.85, 120 Hz: 1.00, 300 Hz: 1.17, 1 kHz: 1.32, 10 kHz: 1.45, 50 kHz or more: 1.50.

Typical Applications

• General Purpose Power Filtering — Bulk energy storage and smoothing where 330 µF at 180 V and elevated temperature endurance are required.
• High‑frequency Ripple Mitigation — Use where significant high‑frequency ripple current (up to 1.8 A at 50 kHz) must be absorbed without degrading performance.
• Industrial and Commercial Electronics — Systems that demand sustained operation up to 105°C and long life under continuous ripple loading.

Unique Advantages

• Proven 105°C Endurance — Rated to endure 3000 hours at 105°C with applied rated ripple current, supporting designs that operate at elevated temperatures.
• Dual‑frequency Ripple Capability — Specified ripple ratings at both 120 Hz and 50 kHz provide predictable performance across power‑conversion and switching environments.
• Compact Snap‑in Form Factor — φ20 × 30 mm radial can with snap‑in terminals simplifies secure PCB mounting while saving board area.
• Predictable Loss Characteristics — Low tanδ (0.15 at 120 Hz, 20°C) supports efficient energy storage with controlled dissipation.
• RoHS Compliance and Production Availability — Environmentally compliant and available in mass production with tray packing for ease of procurement and assembly.
