LLG2D182MELB40

The LLG2D182MELB40 is an aluminum electrolytic capacitor from Nichicon's LLG series, featuring a snap‑in terminal configuration and a compact case designed for equipment downsizing. It provides 1.8 mF capacitance at a 200 V rated voltage with polarization and ±20% tolerance, targeting general‑purpose power applications that require reliable bulk capacitance and ripple handling.

Designed for -40°C to 85°C operation and RoHS compliance, this part balances energy storage, ripple capability, and a smaller case footprint compared with the LLS family, making it suitable for space‑constrained industrial and power electronics designs.

Key Features

• Capacitance & Voltage: 1.8 mF capacitance rated at 200 V, suitable for bulk energy storage and smoothing in DC circuits.
• Snap‑in Radial Can Package: Snap‑in terminal mounting in a radial can package provides secure board retention for power assemblies and simplified insertion during assembly.
• Compact Case Size: One rank smaller case sized than LLS, enabling equipment downsizing where board space and enclosure volume are constrained.
• Temperature & Lifetime: Operates from -40°C to 85°C with a rated endurance of 2000 hours at 85°C under D.C. bias plus rated ripple current.
• Ripple Current Performance: Supports ripple currents of 3.32 A at 120 Hz and 4.98 A at 100 kHz, enabling effective smoothing under both low‑ and high‑frequency ripple conditions.
• Polarized with ±20% Tolerance: Polarized electrolytic construction with a capacitance tolerance of -20% to +20% for predictable performance in power circuits.
• RoHS Compliant: Conforms to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Power Supplies: Bulk smoothing and energy storage in switch‑mode and linear power supplies where 200 V rated capacitance is required.
• Industrial Power Electronics: Filtering and ripple suppression in motor drives, inverters, and industrial controllers that benefit from higher ripple current capability.
• Equipment Downsizing Projects: Use in designs prioritizing reduced case volume—smaller case size than LLS helps shrink overall product footprint.

Unique Advantages

• Space‑Efficient Form Factor: Smaller case size than the LLS series allows designers to reclaim PCB and enclosure space without sacrificing bulk capacitance.
• High Ripple Capability: Specified ripple currents at both 120 Hz and 100 kHz enable flexible use across a range of power conversion topologies and switching frequencies.
• Robust Temperature Endurance: Rated for operation to 85°C with a 2000‑hour endurance at that temperature, providing predictable life under elevated thermal stress.
• Easy Mounting: Snap‑in terminals deliver reliable mechanical retention for assemblies subject to vibration or handling during manufacturing.
• Regulatory Compliance: RoHS compliance supports use in markets and products that require restricted‑substance conformance.
