LGN2W151MELA30

The LGN2W151MELA30 is a snap‑in terminal aluminum electrolytic capacitor designed for high‑voltage, general‑purpose power applications. It combines a compact radial can snap‑in package with a 450 V rating and 150 µF capacitance for bulk energy storage and ripple filtering.

Engineered for elevated‑temperature operation, this part is rated to +105°C with a 3000‑hour endurance under rated ripple current. The LGN series also offers a one‑rank smaller case than the LGU series and is RoHS compliant.

Key Features

• Capacitance & Voltage — 150 µF capacitance at a 450 V rated voltage, suitable for high‑voltage smoothing and energy storage in power circuits.
• High Temperature Endurance — Rated for operation up to +105°C with specified endurance of 3000 hours under DC bias plus rated ripple current.
• Snap‑in Radial Can Package — Snap‑in terminal mounting for secure board installation and high current handling in compact assemblies; package dimensions approximately L: 3.0 × D: 2.5 cm.
• Ripple Current Capability — Rated ripple current of 790 mA at 120 Hz and 1.13 A at 100 kHz, enabling effective ripple suppression across low and high frequency domains.
• Stability & Tolerance — Capacitance tolerance of ±20% at 120 Hz, 20°C and endurance characteristics that limit capacitance change to within ±20% after 3000 hours at 105°C.
• RoHS Compliance — Conforms to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Power Supplies and Converters — Bulk smoothing and ripple filtering for high‑voltage supplies where 450 V rating and elevated temperature endurance are required.
• Industrial Power Equipment — Energy storage and decoupling in industrial inverters, drives, and high‑voltage power modules operating in elevated ambient temperatures.
• UPS and Backup Systems — Peak load support and voltage stabilization in uninterruptible power systems and large energy‑storage components.
• High‑Voltage Filtering — Frequency‑dependent ripple handling across 120 Hz and 100 kHz regimes for EMI/ripple control in high‑voltage circuits.

Unique Advantages

• Long Endurance at Elevated Temperature — Specified to withstand 3000 hours of rated ripple current at +105°C, providing predictable life performance for hot‑running systems.
• High Voltage Handling — 450 V rating supports higher DC bus voltages without series stacking, simplifying designs and reducing component count.
• Compact Snap‑in Format — One rank smaller case size than the LGU series delivers space savings while retaining snap‑in mounting robustness for high‑current applications.
• Dual‑frequency Ripple Capability — Published ripple current values at both 120 Hz and 100 kHz help designers size capacitors for mixed low‑ and high‑frequency ripple environments.
• Predictable Electrical Stability — Capacitance tolerance of ±20% and defined endurance limits (capacitance change within ±20%, tan δ and leakage current limits after endurance) support reliable BOM and life‑cycle planning.
• Regulatory Compliance — RoHS conformity supports use in regulated markets and simplifies environmental compliance efforts.
