LGN2Z182MELB45

The LGN2Z182MELB45 is a snap-in terminal aluminum electrolytic capacitor designed for high-temperature, general-purpose power applications. This smaller-sized member of Nichicon's LGN series delivers 1.8 mF capacitance at a 180 V rating and is built for sustained ripple performance at elevated temperatures.

As part of the LGN family, the device supports extended endurance at 105°C and is RoHS compliant, making it suitable for designs that require long life under continuous ripple current and compact snap-in mounting.

Key Features

• Capacitance & Voltage — 1.8 mF capacitance rated at 180 V, with a tolerance of −20% to +20% to support bulk energy storage and decoupling roles.
• High-Temperature Endurance — Rated operating temperature up to −40°C to 105°C and specified to withstand 3000 hours application of rated ripple current at 105°C.
• Ripple Current Performance — Rated ripple current of 2.7 A at 120 Hz and 4.05 A at 100 kHz, enabling reliable operation under continuous AC stress.
• Snap-In Radial Can Package — Snap-in terminal mounting and radial can construction for secure PCB insertion and mechanical stability in power assemblies.
• Compact Dimensions — Physical size L: 4.5 × D: 3 cm with a seated height up to 1.772 inch, offering a smaller case option (one rank smaller than LGU) for space-constrained designs.
• Polarized Design — Polar capacitor construction for DC power circuits with specified leakage and tan δ characteristics per datasheet requirements.
• RoHS Compliant — Conforms to RoHS directive (2011/65/EU, (EU)2015/863) for regulatory environmental compliance.

Typical Applications

• General-purpose power circuits — Suitable where 1.8 mF at 180 V bulk capacitance and high-temperature endurance are required.
• High-temperature environments — Use in assemblies that demand sustained performance up to 105°C and long ripple endurance.
• PCB-mounted power modules — Snap-in radial can package designed for secure mounting in power supply and power-management boards.

Unique Advantages

• Designed for sustained ripple loading — Specified to withstand 3000 hours of rated ripple current at 105°C, supporting long operating life under continuous AC stress.
• High ripple capacity across frequencies — Separate ripple current ratings at 120 Hz and 100 kHz provide predictable thermal and electrical performance in both low- and high-frequency applications.
• Space-efficient form factor — One rank smaller case than the LGU series offers reduced board footprint without sacrificing endurance.
• Wide operating temperature range — −40°C to 105°C rating accommodates designs that must operate across broad environmental conditions.
• Regulatory compliance — RoHS conformity supports deployment in markets requiring restricted substance compliance.
