LLG2Z122MELA40

The LLG2Z122MELA40 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LLG series, designed for compact, general‑purpose power applications. It delivers 1.2 mF of capacitance at a 180 V rating in a radial, snap‑in can that is one rank smaller than the LLS series—making it suitable for equipment downsizing.

This RoHS‑compliant component offers a broad operating range (–40 °C to 85 °C) and engineered endurance for steady long‑term performance in power conversion and other industrial electronics where space and reliable energy storage matter.

Key Features

• Capacitance & Voltage — 1.2 mF capacitance rated at 180 V for energy storage and filtering in power circuits.
• Package & Mounting — Radial, snap‑in can package with snap‑in terminals for secure PCB installation and fast assembly; size approximately L: 4 × D: 2.5 cm.
• Compact Footprint — One rank smaller case than the LLS series, suited for equipment downsizing and tighter board layouts.
• Temperature & Lifetime — Operating temperature range –40 °C to 85 °C and rated endurance of 2000 hours at 85 °C to support sustained operation in elevated ambient conditions.
• Ripple Current Performance — Rated ripple current of 3 A at 120 Hz and 4.5 A at 100 kHz to handle AC ripple in power supply and converter applications.
• Tolerance & Polarization — ±20% capacitance tolerance; polarized device for correct polarity installation.
• Series Endurance Criteria — Meets series endurance requirements after 2000 hours at 85 °C (capacitance change within ±20%, tan δ within 200% of initial, leakage current not exceeding initial specified value).
• Environmental Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Compact Power Conversion — Energy storage and smoothing in compact AC/DC and DC/DC converters where board space is constrained.
• Industrial Power Supplies — Bulk filtering and ripple handling in general‑purpose industrial power modules.
• Equipment Downsizing Projects — Replacement or redesign efforts requiring smaller case sizes without sacrificing capacitance or voltage rating.

Unique Advantages

• Space‑efficient form factor: One rank smaller than LLS enables denser board layouts and supports equipment miniaturization.
• Robust ripple capability: Specified ripple currents at both 120 Hz and 100 kHz provide predictable performance across low and high frequency ripple conditions.
• Designed for endurance: 2000 hours at 85 °C endurance with defined post‑test limits for capacitance, tan δ and leakage current supports long‑term reliability planning.
• Ease of assembly: Snap‑in terminals simplify PCB installation and mechanical retention for production environments.
• Regulatory compliance: RoHS conformity supports environmental and regulatory requirements for commercial and industrial products.
