LLG2G271MELZ40

The LLG2G271MELZ40 is a Nichicon LLG series aluminum electrolytic capacitor in a snap-in terminal, designed for compact, general-purpose power applications. It delivers 270 µF at a rated 400 V in a smaller-case snap-in can that supports equipment downsizing.

Key technical attributes include a snap-in radial can package, RoHS compliance, an operating temperature range of -25°C to 85°C (for 400 V), and an endurance rating of 2000 hours at 85°C under rated DC bias plus rated ripple current.

Key Features

• Capacitance & Voltage: Rated capacitance of 270 µF at 400 V for bulk energy storage and DC link applications where high voltage rating is required.
• Package & Mounting: Snap-in terminal, radial can package for secure board mounting and simplified assembly in power assemblies.
• Compact Form Factor: One rank smaller case size than LLS, suited for equipment downsizing while retaining high voltage capability.
• Temperature and Endurance: Operating temperature range of -25°C to 85°C (for 400 V); endurance specified as 2000 hours at 85°C with rated DC bias plus rated ripple current.
• Ripple Current Performance: Rated ripple current of 1.5 A at 120 Hz and 2.145 A at 100 kHz to support AC ripple handling across frequency ranges.
• Leakage Current Specification: Leakage current meets I ≤ 3√(C·V) (µA) after 5 minutes' application of rated voltage at 20°C, per datasheet criteria.
• Loss and Stability: Tangent of loss angle (tan δ) max 0.15 at rated voltages up to 400 V (measured at 120 Hz, 20°C); low-temperature impedance guidance available in datasheet.
• Tolerance & Polarization: Capacitance tolerance ±20% and polarized construction per electrolytic capacitor standard practice.
• Regulatory Compliance: Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).
• Physical Size: Body dimension approximately L: 4 × D: 2.2 cm, available in a snap-in can format for board-level power modules.

Typical Applications

• General-purpose power modules: Provides bulk capacitance and DC link support at 400 V where board-level snap-in mounting and compact size help reduce enclosure volume.
• Industrial power electronics: Suitable for equipment that requires high-voltage electrolytic capacitance with defined endurance at elevated operating temperatures.
• Energy smoothing and filtering: Used to smooth DC bus ripple and support transient currents in systems needing 270 µF at 400 V with rated ripple handling.

Unique Advantages

• Space-saving design: One rank smaller case than the LLS series enables reduced board footprint and system downsizing without lowering voltage rating.
• High-voltage capability: 400 V rating provides headroom for high-voltage DC link and power infrastructure requirements.
• Verified endurance: 2000 hours at 85°C under rated bias and ripple gives a measurable reliability baseline for thermal and electrical stress.
• Frequency-aware ripple specs: Separate ripple current ratings at 120 Hz and 100 kHz support informed design choices across low and high-frequency ripple environments.
• Measured electrical limits: Datasheet-specified leakage current formula and tan δ value enable predictable performance verification during qualification.
• RoHS compliant: Meets current RoHS directives for use in regulated markets and products.
