LLG2C122MELB25

The LLG2C122MELB25 is a Nichicon LLG series aluminum electrolytic capacitor with a snap-in terminal configuration, designed for general-purpose applications. It delivers 1.2 mF capacitance at a 160 V rating and is optimized for equipment downsizing, featuring a one-rank-smaller case than the LLS series while remaining RoHS compliant.

Engineered for reliable power filtering under elevated ripple and temperature conditions, this snap-in radial can offers a balance of capacitance, ripple handling and endurance for compact electronic equipment.

Key Features

• Capacitance & Voltage — 1.2 mF (1200 µF) rated at 160 V for energy storage and bulk filtering in DC circuits.
• Snap-in Radial Can Package — Snap-in terminal mounting for secure board retention and simplified assembly in vertical configurations; smaller-case design compared to LLS for equipment downsizing.
• Ripple Current Handling — Rated ripple current of 3.05 A at 120 Hz and 4.575 A at 100 kHz, enabling effective smoothing of AC ripple across a range of frequencies.
• Temperature Range & Endurance — Specified operating range down to –40 °C and up to +85 °C, with endurance of 2000 hours at 85 °C under rated DC bias plus rated ripple.
• Leakage & Tolerance — Capacitance tolerance ±20%; typical leakage behavior consistent with Nichicon LLG series specifications (leakage current for this part listed at 1.31 mA in the series dimension table).
• Polarized Electrolytic — Polarized design for DC applications requiring high capacitance per volume.
• Regulatory — Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Compact power supplies — Bulk filtering and energy storage where smaller case size helps reduce overall equipment footprint.
• General-purpose power smoothing — DC link and decoupling in electronic systems requiring polarized electrolytic capacitance.
• Industrial and commercial electronics — Use in equipment that benefits from high ripple capability and extended endurance at elevated temperatures.

Unique Advantages

• Space-efficient form factor: One-rank-smaller case compared to LLS enables tighter packaging and board-level downsizing without sacrificing capacitance.
• High ripple capability across frequencies: Dual ripple ratings (3.05 A at 120 Hz, 4.575 A at 100 kHz) support effective smoothing of both low- and high-frequency ripple components.
• Endurance at elevated temperature: 2000 hours at 85 °C under rated conditions provides measured reliability for sustained operation.
• Wide operating temperature: –40 °C to +85 °C supports deployment across a broad range of environmental conditions.
• Regulatory compliance: RoHS conformity simplifies use in designs requiring restricted-substance compliance.
