LLG2E182MELC45

The LLG2E182MELC45 is an aluminum electrolytic capacitor in Nichicon’s LLG series, featuring a snap‑in terminal radial can designed for smaller-sized assemblies. It is a polarized, general-purpose capacitor rated for 250 V with a nominal capacitance of 1.8 mF, optimized for equipment where compact size and reliable power handling are required.

Key value propositions include a reduced case size compared with larger siblings in the series, robust ripple-current capability across low and high frequencies, and operation across a wide temperature range, making it suitable for a variety of general-purpose power applications.

Key Features

• Core Construction – Aluminum Electrolytic Polarized electrolytic design providing 1.8 mF capacitance at a 250 V rating for power filtering and energy storage in general-purpose circuits.
• Compact Snap‑in Package Radial, can-style snap‑in mounting for secure board retention and simplified PCB assembly; one rank smaller case size compared to the LLS series to support equipment downsizing.
• Operating Range & Temperature Operational from −40 °C to +85 °C for the 160–250 V category; designed for typical ambient conditions encountered in industrial and general-purpose electronics.
• Endurance & Lifetime Rated lifetime of 2000 hours at 85 °C when subjected to DC bias plus rated ripple current; post‑endurance requirements include capacitance within ±20%, tan δ within 200% of initial spec, and leakage current at or below initial specified value.
• Ripple Current Performance Supports 4.55 A at 120 Hz (low frequency) and 6.825 A at 100 kHz (high frequency), enabling effective smoothing under both mains‑frequency and high‑frequency ripple conditions.
• Electrical Characteristics Capacitance tolerance ±20%; leakage current specified by the datasheet formula I ≤ 3√CV (μA) after 5 minutes at 20 °C; tangent of loss angle (tan δ) for the 160–400 V range is specified up to 0.15 (measured at 120 Hz, 20 °C).
• Environmental Compliance RoHS compliant (2011/65/EU, (EU)2015/863), suitable for applications requiring lead‑free components.

Typical Applications

• General‑Purpose Power Circuits Bulk filtering and energy buffering in general-purpose power supplies and converter DC links where a 250 V rated electrolytic is required.
• Equipment Downsizing Applications that benefit from reduced capacitor footprint—useful when shrinking power electronics assemblies while maintaining capacitance and voltage rating.
• Industrial and Commercial Electronics Filtering and smoothing in control equipment, power distribution modules, and other general-purpose industrial electronics that operate within the specified temperature and lifetime envelope.

Unique Advantages

• Smaller Case Footprint: One rank smaller case size than the LLS series enables more compact designs and better use of enclosure space.
• High Ripple‑Current Capability: Defined ripple current ratings at both 120 Hz and 100 kHz support effective suppression of low‑ and high‑frequency ripple, improving power stability.
• Designed Endurance: 2000 hours at 85 °C with DC bias plus rated ripple current provides predictable performance over the specified lifetime, with post‑test limits for capacitance, tan δ, and leakage current.
• Controlled Leakage Behavior: Leakage current bound by the datasheet formula I ≤ 3√CV after initial application of rated voltage, allowing engineered designs to account for self‑discharge characteristics.
• RoHS Compliance: Meets RoHS directive requirements, simplifying regulatory compliance for assemblies destined for regulated markets.
• Snap‑in Mounting: Robust mechanical retention for printed circuit boards and easier handling during assembly compared with loose or glued components.
