LLG2Z272MELB50

The LLG2Z272MELB50 is an aluminum electrolytic capacitor in Nichicon's LLG series featuring a snap-in terminal, designed for general-purpose power applications. With a 2.7 mF capacitance at a 180 V rating and a compact can-style snap-in package, it is intended for equipment downsizing—offering a one-rank smaller case than the LLS series.

Engineered for demanding ripple environments and extended operation at elevated temperatures, this component provides high ripple current capability, RoHS compliance, and a rated lifetime of 2000 hours at 85°C for reliable long-term use in commercial and industrial power systems.

Key Features

• Capacitance & Voltage — 2.7 mF capacitance with a rated voltage of 180 V, suited for bulk energy storage and filtering in medium-voltage DC applications.
• Compact Snap‑In Package — Radial, can-style snap-in termination for secure PCB mounting and reduced assembly time; one rank smaller case size than LLS for equipment downsizing.
• Ripple Current Performance — Rated ripple current of 4.7 A at 120 Hz and 7.05 A at 100 kHz, supporting heavy AC ripple and switching-power environments.
• Temperature & Endurance — Operates from −40°C to +85°C with a specified endurance of 2000 hours at 85°C under DC bias plus rated ripple current.
• Reliability Characteristics — Capacitance tolerance −20% to +20% at 120 Hz, 20°C; leakage current governed by I ≤ 3√CV (μA) after 5 minutes’ application of rated voltage at 20°C (series specification).
• Regulatory Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).
• Polarized Design — Polarized aluminum electrolytic suitable for DC filtering and bulk storage applications where polarity is maintained.
• Physical Size — Package dimensions approximately L: 5 × D: 3 cm, enabling denser power assemblies.

Typical Applications

• Power Supply Filtering — Bulk smoothing and ripple reduction in commercial and industrial DC power supplies, leveraging high capacitance and ripple current ratings.
• Power Conversion & Inverters — Energy storage and decoupling in converter stages where rated voltage and high ripple capability are required.
• Industrial Electronics — General-purpose filtering and energy buffering in factory automation, robotics controllers, and instrumentation.
• Commercial Equipment — Support for power management in UPS systems, LED drivers, and other medium-voltage commercial devices.

Unique Advantages

• Smaller Case for Downsizing: One rank smaller case size than LLS allows designers to reduce overall equipment footprint without sacrificing capacitance.
• High Ripple Handling: Dual-frequency ripple ratings (4.7 A at 120 Hz and 7.05 A at 100 kHz) enable reliable performance across both low- and high-frequency ripple environments.
• Extended High‑Temperature Endurance: 2000 hours at 85°C under rated conditions supports durability in elevated-temperature applications.
• Regulatory Compliance: RoHS conformity simplifies end-product regulatory alignment for commercial markets.
• Secure Snap‑In Mounting: Snap-in radial package provides robust mechanical retention for high-vibration or mechanically demanding assemblies.
