LGN2V271MELZ40

The LGN2V271MELZ40 is a snap‑in terminal aluminum electrolytic capacitor designed for general‑purpose power applications. It delivers 270 µF at 350 V in a compact radial can with snap‑in mounting and is specified for operation to 105°C.

Key value propositions include 3000 hours of rated ripple‑current endurance at 105°C, a one‑rank smaller case size compared with the LGU series, and RoHS compliance—providing a compact, high‑temperature, long‑life capacitor option for industrial and electronic designs.

Key Features

• Capacitance & Voltage — 270 µF rated capacitance at 350 V for energy storage and smoothing in higher‑voltage circuits.
• High‑Temperature Endurance — Specified to withstand 3000 hours of rated ripple current at 105°C; endurance limits include capacitance change within ±20%, tan δ ≤ 200% of initial, and leakage current ≤ initial specified value after the test.
• Package & Mounting — Radial, can‑type snap‑in package for secure PCB mounting; physical size L: 4 cm × D: 2.2 cm with a seated height maximum of 1.575 inch.
• Ripple Current Capability — Rated ripple current of 1.1 A at 120 Hz and 1.573 A at 100 kHz to support AC ripple handling at common power frequencies and higher switching frequencies.
• Temperature Range & Stability — Operating range −25°C to +105°C for the 350 V rating; low‑temperature impedance stability of Z(−25°C)/Z(+20°C) up to 8 for 350–600 V parts.
• Leakage & Loss Characteristics — Leakage current conforms to I ≤ 3/√C (µA) after 5 minutes at 20°C; tangent of loss angle (tan δ) max of 0.15 for rated voltages up to 420 V.
• Environmental Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).
• Polarity — Polarized capacitor suitable for DC bias applications.

Typical Applications

• General Purpose — Used where a 350 V, 270 µF polarized electrolytic is required for energy storage or smoothing while operating up to 105°C.
• General Purpose — Suitable for board‑level snap‑in mounting in systems that need compact high‑voltage capacitance with defined ripple capability.
• General Purpose — Appropriate for designs requiring RoHS‑compliant aluminum electrolytic capacitors with validated long‑term endurance at elevated temperature.

Unique Advantages

• Validated 105°C Endurance: 3000 hours at rated ripple current provides predictable long‑term behavior for high‑temperature deployments.
• Compact, One‑Rank Smaller Case: Smaller case size than LGU series helps reduce board footprint without sacrificing rated voltage or capacitance.
• Robust Ripple Performance: Specified ripple current at both 120 Hz and 100 kHz supports a range of power and switching environments.
• Clear Electrical Limits: Leakage current and tan δ specifications allow straightforward thermal and leakage budgeting in designs.
• RoHS Compliant: Meets 2011/65/EU and (EU)2015/863 requirements for environmental compliance.
• Snap‑In Mounting: Radial snap‑in terminals simplify secure PCB integration for higher‑voltage assemblies.
