LLG2C182MELA45

The LLG2C182MELA45 is an aluminum electrolytic capacitor from Nichicon's LLG series featuring a snap-in terminal radial can package. Engineered as a one-rank-smaller case than the LLS series, it is suited for equipment downsizing and compact power assemblies.

With a rated capacitance of 1.8 mF at 160 V, polarized construction, RoHS compliance, and specified ripple-current capability across low and high frequencies, this part targets general-purpose electronic applications requiring compact, high-voltage electrolytic energy storage.

Key Features

• Electrical performance — Rated capacitance 1.8 mF (1800 μF) at 160 V; polarized aluminum electrolytic topology for general-purpose use.
• Compact snap-in package — Radial can with snap-in terminals; one rank smaller case than LLS to support equipment downsizing. Size: 25 × 45 mm (L × D: 4.5 × 2.5 cm).
• Temperature range & endurance — Operating temperature range –40 °C to +85 °C. Endurance specified as 2000 hours at 85 °C under DC bias plus rated ripple current.
• High ripple-current capability — Rated ripple current: 3.8 A at 120 Hz and 5.7 A at 100 kHz (part-specific values provided).
• Loss and low-temperature stability — Tangent of loss angle (tan δ) max 0.15 (measurement: 120 Hz, 20 °C). Impedance stability at low temperature: Z(–25 °C)/Z(+20 °C) ≤ 4 for the applicable voltage range.
• Tolerance and leakage — Capacitance tolerance ±20% (120 Hz, 20 °C). Leakage current guideline: I ≤ 3√CV (μA) after 5 minutes at 20 °C; part-specific leakage current listed as 1.60 mA in the LLG series dimension table.
• Environmental compliance — Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose electronic equipment — Provides bulk capacitance and energy storage where a polarized aluminum electrolytic is required for general-purpose functions.
• Equipment downsizing — One rank smaller case size than the LLS series makes it suitable for designs prioritizing reduced PCB footprint and compact assemblies.
• Snap-in mounting systems — Designed for assemblies that use radial, snap-in can packages for robust board mounting and handling.

Unique Advantages

• Smaller-case benefit: One rank smaller than LLS allows designers to reduce enclosure and PCB real estate without changing capacitor family.
• High-voltage, high-capacitance option: 1.8 mF at 160 V provides substantial stored energy in a compact snap-in package.
• Specified ripple performance: Clear ripple-current ratings at 120 Hz and 100 kHz support selection against thermal and ripple requirements.
• Defined endurance: 2000 hours at 85 °C under rated conditions provides a measurable lifecycle parameter for thermal design and reliability planning.
• Series-level consistency: LLG series data (rated voltage and capacitance ranges) enables scaling within the same family for design variants.
• Regulatory compliance: RoHS conformity supports environmental and regulatory requirements for many markets.
