LGN2E271MELZ25

The LGN2E271MELZ25 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LGN series, designed for general‑purpose power applications. It provides 270 µF capacitance at a 250 V rating in a compact φ22 × 25 mm can and is optimized for high ripple handling and extended endurance at elevated temperatures.

Engineered for applications that require reliable bulk capacitance and ripple suppression, this capacitor combines snap‑in mounting for secure board placement, RoHS compliance, and tray packing for production workflows.

Key Features

• Capacitance and Voltage — 270 µF nominal capacitance with a rated voltage of 250 V and a capacitance tolerance of −20% to +20%.
• Snap‑in Can Package — Radial, snap‑in can construction (φ22 × 25 mm) for robust PCB mounting and easy assembly in power modules and racks.
• High Ripple Current Capability — Low‑frequency ripple current of 1.1 A (120 Hz) and high‑frequency ripple current of 1.65 A (100 kHz) for effective smoothing in switching and rectifier circuits.
• Thermal Endurance — Rated for operation from −40 °C to +105 °C with endurance of 3000 hours at 105 °C under rated ripple conditions.
• Leakage and Dissipation — Low leakage current specified at 770 µA and tangent of loss angle (tan δ) of 0.15 measured at 20 °C, 120 Hz.
• Production‑Ready Packaging — Supplied in tray packing and listed as mass production status for stable procurement and assembly planning.
• Environmental Compliance — RoHS compliant per the product information.

Typical Applications

• Industrial Power Supplies — Bulk filtering and ripple suppression up to 250 V with high ripple current capability and extended 105 °C endurance.
• DC–DC Converters and Inverters — Energy storage and smoothing for power conversion stages that demand sustained ripple handling and thermal reliability.
• Motor Drive Power Sections — DC link and decoupling use where polarized high‑capacitance solutions and robust ripple performance improve system stability.

Unique Advantages

• Extended high‑temperature life — 3000 hours endurance at 105 °C ensures long service life under sustained thermal and electrical stress.
• Strong ripple performance — Dual ripple ratings (1.1 A at 120 Hz and 1.65 A at 100 kHz) support both low‑ and high‑frequency power stages.
• Compact snap‑in form factor — φ22 × 25 mm can delivers 270 µF in a smaller case size for space‑constrained power assemblies.
• Low leakage and controlled dissipation — 770 µA leakage current and tan δ = 0.15 (20 °C, 120 Hz) help maintain efficiency and predictable thermal behavior.
• Production convenience — Tray packing and mass production availability simplify procurement and assembly for volume designs.
• RoHS compliant — Meets environmental restrictions for use in regulated markets.
