LLS2G271MELB

The LLS2G271MELB from Nichicon is an aluminum electrolytic, snap-in terminal capacitor in the LLS series designed for general-purpose power applications. It delivers 270 µF capacitance at a 400 V rating with a snap-in radial can package and tray packing for volume assembly.

Engineered for sustained operation at elevated ripple stress, this part combines a high working voltage, sizable capacitance and proven endurance to support power filtering and DC bus energy storage in industrial and commercial equipment where a -25°C to 85°C operating range is required.

Key Features

• Electrical Characteristics — 270 µF nominal capacitance with ±20% tolerance and a 400 V rated voltage suitable for high‑voltage power circuits.
• Low Loss — Tangent of loss angle (tanδ) specified at 0.15 (max) measured at 20°C and 120 Hz, supporting stable performance under AC ripple conditions.
• High Ripple Endurance — Rated ripple current of 1.82 A at 120 Hz (low frequency) and 2.603 A at 50 kHz (high frequency), enabling continuous ripple handling in demanding power supply environments.
• Leakage and Reliability — Specified leakage current of 980 µA and designed to meet endurance requirements of 3000 hours at 85°C; after endurance testing, capacitance remains within ±20%, tanδ stays ≤200% of initial spec, and leakage is ≤ initial specified value.
• Mechanical & Mounting — Snap-in terminal, radial can package (φ30 × 30L / approximately 3 × 3 cm), suitable for robust board mounting in assembled systems. Tray packing supports higher-volume manufacturing.
• Operating Environment — Rated for operation from -25°C to 85°C; compliant to RoHS (2011/65/EU,(EU)2015/863).

Typical Applications

• General Purpose Power Filtering — Bulk smoothing and decoupling in power supplies that require a 400 V working voltage and substantial capacitance.
• DC Bus / Energy Storage — Energy buffering on DC bus lines where high ripple current capability and long endurance at 85°C are required.
• Industrial and Commercial Equipment — Applications needing a robust, snap-in aluminum electrolytic with tray packing for production assembly and long operational life.

Unique Advantages

• High Voltage Capability: 400 V rating provides headroom for high-voltage power rails without changing capacitor family.
• Substantial Capacitance in a Compact Can: 270 µF available in a φ30 × 30L radial can supports significant energy storage in a modest footprint.
• Rated Ripple Performance: Defined low- and high-frequency ripple ratings (1.82 A at 120 Hz; 2.603 A at 50 kHz) let designers quantify thermal and lifetime stress for reliability planning.
• Long Endurance at Elevated Temperature: Specified 3000 hours at 85°C under rated ripple current demonstrates sustained performance for long service intervals.
• Manufacturing-Friendly Packaging: Snap-in terminals and tray packing simplify placement and secure mechanical retention for production assemblies.
• RoHS Compliant: Meets RoHS requirements (2011/65/EU,(EU)2015/863) for environmental and regulatory alignment.
