LGU2Z271MELY

The LGU2Z271MELY from Nichicon is a snap‑in terminal aluminum electrolytic capacitor designed for general‑purpose power applications. It combines a 270 µF capacitance at a 180 V rating with a compact φ20 × 30 mm can and snap‑in mounting for robust board retention and high current handling.

Engineered for sustained operation up to 105°C, this part is targeted at industrial and commercial power electronics where high ripple endurance, long life, and low loss are required.

Key Features

• Capacitance & Voltage — 270 µF nominal capacitance at a 180 V rated voltage with ±20% tolerance, suitable for bulk energy storage and filtering in higher‑voltage circuits.
• High‑temperature Endurance — Rated for 3000 hours at 105°C under rated ripple current, providing predictable life performance in elevated operating temperatures.
• Low Loss Characteristic — Tangent of loss angle (tan δ) specified at 0.15 (measurement at 120 Hz, 20°C for this voltage class), minimizing heat generation and improving efficiency in AC‑ripple environments.
• Ripple Current Capability — 1100 mA at 120 Hz (low frequency) and 1650 mA at 50 kHz (high frequency), enabling effective ripple handling across common switching and line‑frequency conditions.
• Leakage Current & Polarization — Leakage current specified at 660 µA; the capacitor is polarized and intended for DC applications where polarity is observed.
• Package & Mounting — Radial, can-style snap‑in package (φ20 × 30 mm) supplied in tray packing for straightforward assembly and reliable mechanical mounting.
• Wide Operating Range & Compliance — Operates from −40°C to 105°C and is RoHS‑compliant, supporting environmentally regulated designs.

Typical Applications

• Power Supply Smoothing — Bulk filtering and smoothing in high‑voltage DC power supplies and intermediate bus capacitors where 180 V working voltage and high ripple endurance are required.
• Switch‑Mode Power Supplies (SMPS) — Output filtering and energy buffering in commercial and industrial SMPS designs that demand high ripple current capability at both low and high frequencies.
• Motor Drives & Inverters — DC link and smoothing duties in industrial drive electronics where sustained operation at elevated temperature improves system reliability.
• Energy Storage & Hold‑up — Short‑term energy storage for hold‑up and transient suppression in power conversion and control systems.

Unique Advantages

• Proven High‑Temperature Life: 3000 hours at 105°C under rated ripple current provides designers with a clear endurance benchmark for thermal‑stress applications.
• Measured Low Loss: Specified tan δ of 0.15 at the rated voltage reduces dissipation and heating, helping maintain performance in continuous‑duty systems.
• Dual‑Frequency Ripple Performance: Explicit ripple current ratings at 120 Hz and 50 kHz allow designers to size capacitors confidently for both line‑frequency and switching‑frequency conditions.
• Compact Snap‑in Package: φ20 × 30 mm radial can with snap‑in terminals simplifies PCB mounting and mechanical retention in high‑vibration or heavy‑current layouts.
• RoHS Compliance: Meets RoHS requirements for environmentally guided designs and regulatory consistency.
