LLS2G271MELA

The LLS2G271MELA is a Nichicon LLS series snap-in aluminum electrolytic capacitor rated at 270 µF and 400 V with ±20% tolerance. It is a radial, can-style snap-in terminal capacitor designed for general-purpose applications that require high-voltage capacitance with robust ripple-handling and long endurance.

This part is optimized for designs operating between −25°C and +85°C and offers a combination of high ripple current capability, controlled dissipation factor, and a 3000-hour life at 85°C, making it suitable where long-term stability and reliable performance are required.

Key Features

• Capacitance & Voltage — 270 µF nominal capacitance at a 400 V rated voltage with ±20% tolerance.
• Package & Mounting — Snap-in terminal, radial can (snap-in) package. Physical size: φ25 × 40 mm (L: 4 × D: 2.5 cm) with a seated height specification (1.575 inch).
• Ripple Current Performance — Low-frequency ripple current 1.79 A at 120 Hz and high-frequency ripple current 2.56 A at 50 kHz, supporting high-demand AC ripple environments.
• Loss Tangent (tan δ) — tan δ of 0.20 (max) measured at 20°C and 120 Hz for the 400 V rating, enabling predictable dissipation behavior.
• Leakage Current — Specified leakage current of 980 µA (measured after rated voltage application as defined in the datasheet).
• Endurance & Reliability — Guaranteed to withstand 3000 hours at 85°C with rated ripple current applied; after endurance testing the capacitor meets defined limits for capacitance change (±20%), tan δ, and leakage current.
• Environmental Compliance — RoHS compliant in accordance with the LLS series declaration.

Typical Applications

• General-purpose power systems — Suitable where a 400 V, 270 µF snap-in electrolytic is required for high-voltage filtering and smoothing in power assemblies.
• High-voltage filter and smoothing stages — Used in circuits that require rated ripple handling (1.79 A at 120 Hz / 2.56 A at 50 kHz) and stable dissipation factor at 20°C, 120 Hz.
• Long-life industrial and commercial equipment — Appropriate for applications that demand 3000 hours of endurance at 85°C with consistent capacitance and leakage performance.

Unique Advantages

• High-voltage, high-capacitance combination: 270 µF at 400 V provides bulk capacitance in a compact snap-in can for elevated-voltage designs.
• Reliable ripple handling: Specified ripple currents at both low and high frequencies support stable operation under AC stress.
• Endurance-proven performance: 3000-hour life at 85°C with defined post-test limits for capacitance, tan δ, and leakage, offering predictable long-term behavior.
• Clear thermal range: Rated for operation from −25°C to +85°C, aligning performance expectations with operating environment limits.
• RoHS compliance: Meets RoHS requirements for environmental regulatory alignment.
