LGG2D122MELC25

The LGG2D122MELC25 is a snap-in terminal type aluminum electrolytic capacitor from Nichicon’s LGG series, designed for space-constrained power designs. It delivers 1.2 mF capacitance at a 200 V rating in an ultra-smaller-sized can — one rank smaller than the LGN series — making it suited for equipment downsizing and general-purpose power smoothing.

Engineered for elevated operating conditions, this capacitor is rated to operate from −40°C to +105°C and is RoHS compliant (2011/65/EU, (EU)2015/863), providing a combination of compact packaging and durable performance for high-temperature applications.

Key Features

• Capacitance and Voltage — 1.2 mF capacitance rated at 200 V, providing bulk energy storage and smoothing for 200 V power rails.
• Snap-in, Radial Can Package — Snap-in terminal mounting for secure PCB installation in compact assemblies; package dimensions L: 2.5 × D: 3.5 cm for space-efficient layout.
• High Temperature Rating — Specified operating range of −40°C to +105°C for use in elevated-temperature environments.
• Endurance — Rated lifetime of 2000 hours at 105°C when subjected to D.C. bias plus rated ripple current, supporting sustained performance under thermal stress.
• Ripple Current Capability — Handles 2.3 A at 120 Hz and 3.45 A at 100 kHz, enabling effective filtering of both low- and high-frequency ripple components.
• Polarized Design — Polarized capacitor suitable for conventional power-supply and energy-storage topologies.
• Tolerance — Capacitance tolerance of −20% to +20% as specified at 120 Hz, 20°C.
• Regulatory Compliance — Compliant with RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Compact Power Supplies — Bulk energy storage and smoothing on 200 V rails where board space is limited and downsizing is a priority.
• Industrial Control Equipment — Filtering and decoupling in compact control modules that require operation up to 105°C and extended endurance.
• Power Modules and Conversion — Support for DC-link and bulk-capacitance roles in compact converters and power modules with moderate ripple demands.
• General-Purpose Electronic Equipment — Versatile polarized capacitor for a wide range of general-purpose smoothing and energy-storage needs.

Unique Advantages

• Space-Saving Case Size — One rank smaller than LGN, enabling equipment downsizing without sacrificing capacitance for 200 V applications.
• High-Temperature Endurance — 2000 hours rated life at 105°C under rated stress conditions supports reliability in hot environments.
• Dual-Frequency Ripple Performance — Ripple specifications provided for both 120 Hz (2.3 A) and 100 kHz (3.45 A) to address a range of ripple sources in power designs.
• Robust Operating Range — −40°C to +105°C operating temperature range covers many industrial and commercial environments.
• Regulatory Compliance — RoHS-compliant material set aligns with environmental and regulatory requirements.
• Proven Series Design — Part of Nichicon’s LGG snap-in series, offering consistent mechanical and electrical characteristics for repeatable design integration.
