LLS2E271MELZ

The LLS2E271MELZ is an aluminum electrolytic, snap-in terminal capacitor engineered for general-purpose power applications. It pairs a 270 µF rated capacitance with a 250 V voltage rating in a radial can snap-in package optimized for robust power-rail use.

Designed for demanding ripple environments and long-term operation, this part delivers high ripple-current capability, low leakage, and a 3000-hour endurance at 85°C, making it suitable for industrial and commercial power systems requiring reliable bulk capacitance and smoothing.

Key Features

• Capacitance & Voltage — 270 µF nominal capacitance with a 250 V rated voltage and ±20% tolerance, providing substantial bulk energy storage for high-voltage DC rails.
• Snap-In Radial Can Package — Snap-in terminal mounting for secure board retention and easy installation in power assemblies; package dimensions: Ø22 × 25 mm (L: 2.5 × D: 2.2 cm).
• High Ripple Current — Supports 1.5 A at 120 Hz (low frequency) and 2.25 A at 50 kHz (high frequency), enabling effective smoothing under significant AC ripple loads.
• Endurance & Temperature Range — Qualified for 3000 hours at 85°C and rated for operation from −40°C to +85°C, supporting long service life in elevated-temperature environments.
• Low Leakage & Loss — Specified leakage current around 770 µA and tan δ of 0.15 at 20°C/120 Hz for the 250 V rating, contributing to predictable performance and low dissipation.
• RoHS Compliant & Tray Packing — Compliant with RoHS directives and supplied in tray packing for automated handling and manufacturing readiness.

Typical Applications

• Power Supplies — Bulk filtering and smoothing on high-voltage DC rails where 270 µF at 250 V and high ripple capability improve voltage stability.
• Industrial Power Electronics — Energy storage and decoupling in motor drives, inverters, and converters operating up to +85°C with long endurance requirements.
• Uninterruptible Power and Backup Systems — Supporting transient suppression and charge reservoir functions where low leakage and sustained ripple handling are important.

Unique Advantages

• High ripple tolerance — Rated for 1.5 A @120 Hz and 2.25 A @50 kHz, allowing reliable operation in both low- and high-frequency ripple environments.
• Verified long-term endurance — 3000 hours at 85°C endurance specification provides design confidence for extended field life in elevated-temperature applications.
• Low dissipation and leakage — tan δ of 0.15 and measured leakage current around 770 µA contribute to efficient power handling and predictable aging.
• Robust mechanical mounting — Snap-in radial can package ensures secure board attachment for power modules and rugged assemblies.
• Manufacturing-friendly packaging — Tray packing supports automated placement and production throughput.
