LLG2G271MELA35

The LLG2G271MELA35 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LLG series. It provides 270 µF capacitance at a 400 V rating in a smaller-sized, radial can snap‑in package suited for equipment downsizing.

Designed for general-purpose electronic applications, the part combines a compact footprint with specifications oriented to moderate-temperature environments and sustained performance under rated bias and ripple conditions.

Key Features

• Capacitance & Voltage — 270 µF nominal capacitance with a 400 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• Snap‑in Terminal, Radial Can — Snap‑in mounting type in a radial, can-style package for secure board retention and straightforward assembly.
• Compact, Downsizing‑Friendly — LLG series is one rank smaller in case size than LLS, making this part suited to space-constrained designs.
• Temperature & Endurance — Rated for operation from –25°C to +85°C (for 400 V parts) with an endurance specification of 2000 hours at 85°C under DC bias plus rated ripple current.
• Ripple Current — Rated ripple current of 1.5 A at 120 Hz and 2.145 A at 100 kHz for managing AC stress in power circuits.
• Leakage & Loss Characteristics — Leakage current defined by I ≤ 3√CV (μA) after 5 minutes at 20°C; tan δ (loss tangent) max 0.15 for 160–400 V parts (measured at 120 Hz, 20°C).
• RoHS Compliant — Conforms to the RoHS directive (2011/65/EU, (EU)2015/863).
• Physical Size — Body dimensions approximately L: 3.5 × D: 2.5 cm with a radial snap‑in package.

Typical Applications

• General Purpose Electronics — For circuits requiring a 270 µF, 400 V aluminum electrolytic capacitor in a snap‑in package for bulk smoothing or energy storage.
• Space‑Constrained Equipment — Where reduced case size is needed, the LLG series offers one rank smaller dimensions versus LLS to aid equipment downsizing.
• Board‑Mounted Power Assemblies — Snap‑in terminals and radial can packaging provide secure mounting for assemblies that require robust mechanical retention.
• Moderate‑Temperature Installations — Suitable for applications operating between –25°C and +85°C with a documented 2000‑hour endurance at 85°C under rated conditions.

Unique Advantages

• Compact footprint: One rank smaller case size than LLS enables denser PCB layouts and smaller end products.
• High voltage capability: 400 V rating supports higher-voltage DC bus and power applications within the series’ voltage range.
• Defined endurance: 2000 hours at 85°C under DC bias plus rated ripple current gives predictable long‑term behavior for thermal and electrical stress.
• Measurable electrical limits: Leakage current formula (I ≤ 3√CV) and tan δ ≤ 0.15 at 120 Hz provide clear, testable performance boundaries for design validation.
• Assembly efficiency: Snap‑in terminals in a radial can simplify mounting and improve mechanical stability on the board.
• Regulatory compliance: RoHS conformity supports environmental and regulatory requirements for many markets.
