LGN2G151MELZ35

The LGN2G151MELZ35 is a snap-in terminal aluminum electrolytic capacitor designed for general-purpose power applications. It delivers 150 µF capacitance at a 400 V rating in a compact, radial can snap-in package optimized for reliable ripple handling and extended high-temperature operation.

Key value comes from its 3000 hour endurance under rated ripple current at 105°C and a smaller case size compared with the LGU series, enabling robust performance where space and thermal durability matter.

Key Features

• Capacitance & Voltage — 150 µF nominal capacitance with a 400 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• High-temperature Endurance — Designed to withstand 3000 hours of rated ripple current at 105°C, supporting sustained operation in hot environments.
• Ripple Current Performance — Rated ripple current of 850 mA at 120 Hz and 1.216 A at 100 kHz, enabling effective smoothing and decoupling in power circuits.
• Operating Temperature Range — Specified for −25°C to +105°C operation (consistent with the 350–600 V category in the LGN series).
• Package & Mounting — Radial can, snap-in terminal type for secure PCB mounting and streamlined assembly.
• Polarized Electrolytic — Standard polarized construction for DC power applications.
• Compact Form Factor — Physical size L: 3.5 × D: 2.2 cm with a seated height maximum of 1.378 inch, offering a smaller case profile than the LGU family.
• RoHS Compliant — Meets RoHS directive (2011/65/EU, (EU)2015/863) for lead-free environmental requirements.

Typical Applications

• Power Supplies — Bulk smoothing and ripple filtering in general-purpose AC/DC and DC/DC converter designs where high-voltage filtering is required.
• Industrial Power Equipment — Decoupling and energy storage in industrial power modules that operate at elevated temperatures and demand long endurance.
• General-Purpose Electronic Equipment — Energy storage and transient suppression in a wide range of general-purpose devices requiring a 400 V electrolytic solution.

Unique Advantages

• Extended High-Temperature Life: 3000 hours at 105°C under rated ripple current provides predictable life performance in hot environments.
• Compact, Space-Saving Case: One rank smaller case size than the LGU series helps reduce board area without sacrificing voltage or capacitance.
• High Ripple Capability: Dual-frequency ripple ratings (850 mA at 120 Hz; 1.216 A at 100 kHz) support robust filtering across common power-conversion frequencies.
• Snap-in Mounting: Radial snap-in terminals provide mechanical stability for through-hole assembly and ease of handling during production.
• RoHS Compliance: Meets current RoHS requirements for environmentally regulated designs.
