LGG2Z182MELB45

The LGG2Z182MELB45 is an aluminum electrolytic capacitor from Nichicon's LGG series featuring a snap-in terminal can and a compact φ30 × 45 mm package. It delivers 1.8 mF (1800 µF) capacitance at a 180 V rated voltage, designed for general-purpose use in equipment that requires high-capacitance bulk energy storage in a reduced footprint.

Engineered for reliable operation across a wide temperature range, this part supports an operating temperature of –40 °C to +105 °C and a guaranteed endurance of 2000 hours at 105 °C. It is supplied in tray packing for mass production use and is RoHS compliant.

Key Features

• Capacitance & Voltage — 1.8 mF (1800 µF) rated at 180 V for bulk energy storage and smoothing in mid-voltage applications.
• Snap-In Terminal Package — Radial can with snap-in mounting for secure PCB retention and straightforward assembly in through-hole designs.
• Compact Size — φ30 × 45 mm (L: 4.5 cm × D: 3 cm) package; LGG series offers an ultra-smaller-sized design (one rank smaller case than LGN) to aid equipment downsizing.
• Temperature & Endurance — Rated for –40 °C to +105 °C with 2000 hours endurance at 105 °C under rated DC bias plus rated ripple current.
• Ripple Current Performance — Rated ripple currents of 2.7 A at 120 Hz and 4.05 A at 100 kHz to support AC ripple filtering across a broad frequency range.
• Tolerance & Polarity — Capacitance tolerance of ±20% and polarized design; suitable for circuits designed for electrolytic capacitor polarity.
• Marking & Compliance — Printed in white on a black sleeve; RoHS compliant.
• Production & Packaging — Tray packing intended for mass production assembly and handling.

Typical Applications

• Power Supply Smoothing — Bulk filtering and energy buffering in general-purpose power supplies that require 180 V rated capacitance and extended life at elevated temperatures.
• Industrial Electronics — Decoupling and energy storage in industrial control equipment where –40 °C to +105 °C operation and 2000 h endurance at 105 °C are required.
• High-Voltage DC Bus Support — Energy buffering on mid-voltage DC rails that benefit from 1.8 mF capacitance and snap-in mechanical retention.

Unique Advantages

• High Bulk Capacitance at 180 V — Provides 1.8 mF in a compact snap-in can, enabling fewer components for equivalent stored energy.
• Compact, Snap-In Form Factor — φ30 × 45 mm can and snap-in terminals simplify assembly and board retention while saving board area compared to larger cases.
• Wide Operating Temperature with Defined Endurance — –40 °C to +105 °C rating and 2000 hours at 105 °C give clear thermal and lifespan expectations for design planning.
• Broad Ripple Capability — Specified ripple currents at both 120 Hz and 100 kHz support filtering across low and high-frequency components of ripple.
• Production-Ready Packaging — Tray packing for mass production streamlines handling and assembly in volume manufacturing.
• RoHS Compliant — Meets RoHS requirements for restricted substances.
