LGU2P271MELY

The LGU2P271MELY is a Nichicon LGU series aluminum electrolytic capacitor in a snap‑in terminal (radial can) package. It delivers 270 µF capacitance at a 220 V rated voltage with snap‑in mounting for secure installation in assemblies.

Engineered for general‑purpose applications that require high ripple endurance and long operating life, this capacitor combines a wide operating temperature range with specified low‑loss characteristics and RoHS compliance.

Key Features

• Capacitance & Voltage — 270 µF rated capacitance at 220 V for bulk energy storage and voltage stabilization in higher‑voltage designs.
• Tolerance & Loss — ±20% capacitance tolerance; tan δ (DF) 0.15 maximum at 20°C, 120 Hz for predictable dissipation characteristics.
• High Ripple Current Capability — Rated ripple current of 1.15 A at 120 Hz (low frequency) and 1.725 A at 50 kHz (high frequency) to support designs with significant AC ripple stress.
• Leakage Current — Specified leakage current of 730 µA after rated voltage is applied, supporting controlled standby and charged conditions.
• Endurance & Reliability — 3000 hours life at 105°C with the ability to withstand rated ripple current for the endurance period when operated within specified conditions.
• Temperature Range — Wide operating temperature range of −40°C to +105°C for use across varied environmental conditions.
• Package & Mounting — φ20 × 35 mm (L: 3.5 × D: 2 cm) snap‑in radial can; supplied in tray packing for production use.
• Compliance — RoHS compliant.

Typical Applications

• General‑purpose power systems — Suited to circuits that require 220 V rated capacitance and robust ripple handling for smoothing and bulk storage.
• Power conversion and supplies — Appropriate where high ripple current endurance and long life at elevated temperature (105°C, 3000 h) are required.
• Electronic assemblies with snap‑in mounting — Designed for secure, low‑profile installation in production assemblies using snap‑in terminals and tray packing.

Unique Advantages

• Proven ripple endurance — Rated ripple currents of 1.15 A (120 Hz) and 1.725 A (50 kHz) and 3000 h life at 105°C support continuous operation under ripple stress.
• Wide operating temperature — −40°C to +105°C range enables use in environments with broad temperature fluctuations.
• Low dissipation factor — tan δ of 0.15 (20°C, 120 Hz) reduces heat generation from dielectric losses during operation.
• Compact, production‑friendly package — φ20×35 mm snap‑in can in tray packing simplifies board assembly and handling for mass production.
• Compliance and predictable leakage — RoHS compliance and specified leakage current (730 µA) assist in meeting regulatory and design requirements.
