LGU2W121MELZ

The LGU2W121MELZ is a snap‑in terminal aluminum electrolytic capacitor rated at 120 µF and 450 V, designed for general‑purpose applications that require high voltage handling and sustained operation at elevated temperatures. It is a radial, can‑style snap‑in component engineered for board‑level power applications where long ripple endurance and reliable polarization are required.

Built to withstand continuous ripple stress, this part endures 3000 hours of rated ripple current at 105°C and is RoHS compliant, offering a combination of high‑voltage capability and high‑temperature endurance for demanding designs.

Key Features

• Capacitance & Voltage — 120 µF nominal capacitance with a 450 V rated voltage for high‑voltage filtering and energy buffering.
• High‑Temperature Endurance — Specified to operate up to 105°C and rated to withstand 3000 hours of rated ripple current at 105°C.
• Ripple Current Performance — Supported ripple current values include 800 mA at 120 Hz (low frequency) and 1.144 A at 50 kHz (high frequency), enabling effective AC ripple handling across frequency ranges.
• Package & Mounting — Radial can with snap‑in terminals for secure board mounting and straightforward assembly into power assemblies.
• Electrical Characteristics — Polarized aluminum electrolytic design with ±20% capacitance tolerance at 120 Hz, and a specified tan δ max of 0.20 at the 450 V rating.
• Operating Range & Dimensions — Rated for −25°C to +105°C operation; physical size approximately L: 4 × D: 2.2 cm for PCB layout and enclosure planning.
• Standards Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General Purpose — Designed for general‑purpose electronic equipment that requires a high‑voltage, high‑temperature electrolytic capacitor with snap‑in mounting.
• High‑Temperature Power Systems — Suited to power circuits operating up to 105°C where long ripple endurance (3000 hours at 105°C) is needed.
• High‑Frequency Ripple Environments — Effective in circuits exposed to significant AC ripple across frequency ranges thanks to rated ripple current of 800 mA at 120 Hz and 1.144 A at 50 kHz.

Unique Advantages

• High‑Voltage Capability: 450 V rating enables use in higher‑voltage power stages without series stacking.
• Long‑Term Ripple Endurance: Withstands 3000 hours of rated ripple current at 105°C, supporting reliable operation under sustained stress.
