LGU2F271MELB

The LGU2F271MELB is a 270 µF, 315 V aluminum electrolytic capacitor from Nichicon’s LGU series, configured with a snap‑in terminal for secure board mounting. It is designed for general‑purpose power applications that require high voltage capability, robust ripple current handling and extended endurance at elevated temperatures.

With a rated lifetime of 3000 hours at 105°C and RoHS compliance, this part addresses reliability and environmental requirements for industrial and power electronics designs that demand sustained performance under thermal and electrical stress.

Key Features

• Electrical Capacity — 270 µF capacitance at a rated voltage of 315 V, with a capacitance tolerance of ±20% (120 Hz, 20°C).
• High‑Voltage, High‑Ripple Capability — Rated ripple current handling of 1.16 A at 120 Hz and 1.659 A at 50 kHz, suitable for high‑voltage DC filtering and smoothing tasks.
• Endurance and Reliability — Specified endurance of 3000 hours at 105°C under rated ripple current, and designed to meet performance requirements after DC bias plus rated ripple is applied for that duration.
• Thermal Range — Operating temperature range of −25°C to +105°C for the 315 V rating, supporting operation in elevated temperature environments common to power electronics.
• Leakage and Loss Characteristics — Measured leakage current of 870 µA and tangent of loss angle (tan δ) measured at 120 Hz, 20°C (tan δ max for the 315 V range per series data).
• Package and Mounting — Snap‑in radial can package (φ30×25L) for robust board mounting and straightforward assembly in power modules and enclosures.
• Regulatory — RoHS‑compliant construction.

Typical Applications

• General‑purpose power electronics — Smoothing, filtering and decoupling on high‑voltage DC rails where 315 V capability and significant ripple current handling are required.
• Power supply modules — Bulk and output capacitance in switch‑mode power supplies that operate at elevated temperatures and require reliable long‑term endurance.
• Industrial equipment — Use in power conversion and control systems that need a compact, snap‑in high‑voltage capacitor with defined long‑term ripple performance.

Unique Advantages

• Proven endurance under load — Engineered to withstand 3000 hours of rated ripple current at 105°C, providing predictable longevity in thermally stressed applications.
• High ripple current performance — Specified ripple current at both low and high frequencies enables designers to address broad-spectrum switching and line‑frequency ripple components.
• High‑voltage capability — 315 V rating supports high‑voltage DC rails without stacking or special arrangements, simplifying BOM and layout.
• Compact snap‑in form factor — φ30×25L radial snap‑in can offers robust mechanical retention and straightforward placement in power assemblies.
• Clear electrical characterization — Tangent of loss angle measured at 120 Hz, 20°C and specified leakage current provide engineers with verifiable parameters for design margin calculations.
• RoHS compliance — Meets environmental regulation requirements for restricted substances.
