LLG2Z182MELB40

The LLG2Z182MELB40 from Nichicon is a snap-in terminal aluminum electrolytic capacitor in the LLG series designed for downsized equipment. This polarized, radial can capacitor delivers 1.8 mF of capacitance at a 180 V rating and is optimized for general-purpose power applications where board-level retention and compact footprint matter.

Key value drivers include a smaller case size (one rank smaller than the LLS series), designed endurance at elevated temperature, and RoHS compliance—making it suitable for designs that require compact bulk capacitance and reliable ripple handling.

Key Features

• Electrical Performance — 1.8 mF rated capacitance with ±20% tolerance (measured at 120 Hz, 20°C). Polarized construction for DC power applications.
• Rated Voltage — 180 V DC rating appropriate for mid-voltage power supply and converter stages.
• Ripple Current Capability — Rated ripple handling of 3.6 A at 120 Hz and 5.4 A at 100 kHz, supporting AC ripple and switching regulator environments within specified limits.
• Temperature and Lifetime — Operating temperature range of −40°C to +85°C (category specification for 160–250 V parts). Endurance specified as 2000 hours at 85°C with DC bias plus rated ripple current applied.
• Compact Mechanical Package — Snap-in radial can package for secure board mounting; dimensions approximately L: 4 × D: 3 cm with a maximum seated height of 1.575 inch.
• RoHS Compliance — Conforms to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Power supplies and DC–DC converters — Bulk smoothing and hold-up capacitance in downsized power modules, leveraging the 180 V rating and high ripple current capability.
• Industrial control equipment — Energy buffering and ripple filtering in control and instrumentation systems that require compact, board-mounted electrolytic bulk capacitance.
• Consumer and communications electronics — Smoothing and decoupling in compact systems where a smaller case size (one rank smaller than LLS) helps reduce enclosure and PCB footprint.

Unique Advantages

• Space-saving footprint: One rank smaller case than the LLS series enables equipment downsizing without sacrificing bulk capacitance.
• Strong ripple handling: Rated ripple currents of 3.6 A (120 Hz) and 5.4 A (100 kHz) allow the capacitor to support common AC and switching ripple conditions in power circuits.
• Rated endurance at elevated temperature: 2000 hours at 85°C under DC bias plus rated ripple current provides a defined lifecycle metric for thermal stress planning.
• Robust operating range: Specified for −40°C to +85°C operation (for 160–250 V category), covering a wide set of general-purpose environments.
• Secure board mounting: Snap-in radial can termination delivers reliable mechanical retention for through-hole assembly.
• Regulatory compliance: RoHS conformity supports regulatory requirements for many commercial and industrial products.

Why Choose LLG2Z182MELB40?
