LGG2Z122MELC25

The LGG2Z122MELC25 is a snap-in terminal aluminum electrolytic capacitor from Nichicon’s LGG series, offering 1.2 mF capacitance at a 180 V rating. Designed for general-purpose power applications, it provides high ripple handling and compact snap-in packaging for straightforward board assembly.

Key value propositions include robust high-temperature endurance (2000 hours at 105°C), dual-frequency ripple performance (specified at both 120 Hz and 100 kHz), and RoHS compliance for regulatory consistency in production designs.

Key Features

• Capacitance & Voltage — 1.2 mF (1200 µF) rated at 180 V for energy storage and decoupling in medium-voltage power circuits.
• Tolerance & Polarity — ±20% tolerance and polarized construction for predictable performance in DC applications.
• Dual-frequency Ripple Performance — Low-frequency ripple current 2.15 A (120 Hz) and high-frequency ripple current 3.225 A (100 kHz) to address both mains and switching ripple environments.
• Leakage Current — Specified leakage current of 1390 µA, measured after standard conditioning, for predictable standby and leakage behavior.
• High-temperature Endurance — Rated for 2000 hours at 105°C under DC bias plus rated ripple, supporting long-term reliability in elevated operating temperatures.
• Package & Mounting — Snap-in radial can (φ35 × 25L) for secure board mounting and simplified assembly; supplied in tray packing for production handling.
• Environmental Compliance — RoHS compliant construction to meet regulatory requirements for electronics manufacturing.

Typical Applications

• Power supplies — Bulk smoothing and energy storage where 180 V rating and high ripple current capability reduce voltage ripple and improve regulation.
• Industrial power electronics — Filtering and decoupling in medium-voltage converters and control equipment that operate at elevated temperatures.
• Switch-mode power supplies (SMPS) — Output filtering and ripple absorption for switching regulators, benefiting from specified performance at both 120 Hz and 100 kHz.

Unique Advantages

• High ripple handling: Specified ripple currents at 120 Hz and 100 kHz ensure the capacitor can address both low- and high-frequency ripple sources.
• Designed for high-temperature environments: 2000-hour endurance at 105°C provides a predictable lifetime for designs exposed to elevated temperatures.
• Compact snap-in form factor: φ35 × 25L radial snap-in can simplifies mechanical retention and assembly on the PCB.
• Manufacturer support: Part of Nichicon’s LGG series, offering consistent specifications and production availability for volume designs.
• Regulatory readiness: RoHS compliance supports deployment in markets requiring restricted-substance conformance.
