LGJ2W151MELC20

The LGJ2W151MELC20 is a snap‑in terminal aluminum electrolytic capacitor offering 150 µF capacitance at a 450 V rating in a low‑profile 35 mm × 20 mm can. It is a polarized, snap‑in mount component intended for general‑purpose power applications where high voltage handling and robust ripple performance are required.

Key attributes include a 3000‑hour endurance at 105°C, a measured tangent of loss angle (tanδ) of 0.20 at 20°C and 120 Hz, and rated ripple performance that supports both low‑ and high‑frequency power circuits.

Key Features

• Electrical Performance — 150 µF nominal capacitance with ±20% tolerance and a 450 V rated working voltage for high‑voltage DC energy storage and smoothing.
• Low Loss — tanδ (DF) of 0.20 maximum at 20°C and 120 Hz, providing controlled dissipation for power applications.
• Ripple Handling — Rated ripple current of 1.17 A at 120 Hz and 1.673 A at 50 kHz to support AC ripple and switching frequencies in power circuits.
• Leakage Current — Specified leakage current of 770 µA after rated voltage application, enabling predictable standby and idle behavior.
• Thermal & Endurance — Operating temperature range −25°C to +105°C with endurance rated at 3000 hours at 105°C.
• Package & Mounting — Radial can, snap‑in terminal mounting for secure mechanical retention in power assemblies; physical size φ35 × 20 mm (D × L).
• Production & Packaging — Mass production status with tray packing for board‑level handling and assembly efficiency.

Typical Applications

• Power supplies — Bulk filtering and DC bus smoothing in general‑purpose AC/DC and DC/DC power supplies where a 450 V rating is required.
• Industrial power electronics — Energy storage and ripple suppression in industrial converters and control equipment operating within −25°C to 105°C.
• Switching power stages — Filtering for switching regulator outputs and intermediate DC links that demand defined ripple current capability across low and high frequencies.

Unique Advantages

• High‑voltage capability: 450 V rating enables use on higher DC rails without series stacking.
• Compact low‑profile form: φ35 × 20 mm can size provides high capacitance in a short axial length for denser power assemblies.
• Verified ripple performance: Rated ripple currents at 120 Hz and 50 kHz support both line‑frequency and high‑frequency switching environments.
• Long endurance at elevated temperature: 3000 hours at 105°C supports sustained operation in thermally demanding installations.
• Predictable leakage and dissipation: Specified leakage current (770 µA) and tanδ limit (0.20) help simplify thermal and standby loss calculations.
• Secure mounting and production ready: Snap‑in terminals and tray packing facilitate reliable board retention and scalable assembly.
