LGG2Z182MELC35

The LGG2Z182MELC35 is a Nichicon LGG series aluminum electrolytic capacitor in a snap-in terminal configuration. It delivers 1.8 mF (1800 µF) capacitance at a rated voltage of 180 V in a compact φ35 × 35 mm can, intended for general-purpose power applications.

Designed for equipment downsizing and robust operation, this RoHS-compliant capacitor supports operation from −40 °C to +105 °C and a rated endurance of 2000 hours at 105 °C, making it suitable for a wide range of industrial and electronic power designs requiring high-voltage bulk capacitance with snap-in mounting.

Key Features

• Core Type — Aluminum Electrolytic: Polarized aluminum electrolytic construction providing 1.8 mF capacitance at 180 V for bulk energy storage and smoothing.
• High Voltage Rating: Rated voltage of 180 V to support higher-voltage power rails within the LGG series rated range.
• Compact Snap-in Package: Radial can with snap-in terminals in a φ35 × 35 mm package designed to support secure board mounting and simplified assembly.
• Wide Operating Temperature: Specified for −40 °C to +105 °C operation, enabling deployment across varied environmental conditions.
• Endurance and Reliability: Endurance specified as 2000 hours at 105 °C under DC bias plus rated ripple current; post-test limits include capacitance change within ±20%, tan δ ≤ 200% of initial spec, and leakage current at or below initial specified value.
• Ripple Current Performance: Rated ripple current of 2.7 A at 120 Hz and 4.05 A at 100 kHz, supporting AC ripple handling across low and high frequency domains.
• Low-temperature Impedance Stability: For rated voltages in the 160–250 V range, impedance ratio Z(−25 °C)/Z(+20 °C) is specified to a maximum of 4 (measured at 120 Hz), aiding performance in cooler environments.
• Leakage Current Specification: Leakage current conforms to I ≤ 3√(C·V) µA after 5 minutes’ application of rated voltage at 20 °C, allowing predictable leakage behavior for design calculations.
• Environmental Compliance: RoHS compliant, reflecting adherence to restricted substances requirements listed in the product data.

Typical Applications

• Power supply smoothing: Bulk capacitance for filtering and energy storage on higher-voltage DC rails where 180 V rating and large capacitance are required.
• Industrial power electronics: General-purpose high-voltage bulk capacitor for control and power modules that require robust temperature and ripple performance.
• Equipment with space constraints: Suited to equipment downsizing needs due to LGG series smaller case sizing compared with prior LGN series options.

Unique Advantages

• High-capacitance, high-voltage combination: 1.8 mF at 180 V provides significant bulk energy storage for demanding power rails without requiring multiple smaller components.
• Compact, snap-in form factor: φ35 × 35 mm can with snap-in terminals simplifies mounting and saves PCB assembly time compared to screw or bolt-mounted alternatives.
• Designed for elevated temperatures: 2000-hour endurance at 105 °C gives designers predictable life and performance under continuous high-temperature operation.
• Dual-frequency ripple capability: Specified ripple current at both 120 Hz and 100 kHz supports applications with varied ripple profiles.
• Predictable leakage and impedance behavior: Leakage current formula and low-temperature impedance limits enable engineering calculations for system-level performance and margining.
• RoHS compliance: Meets restricted substances requirements, supporting regulatory needs for many global markets.
