LGU1K222MELZ

The LGU1K222MELZ is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LGU series designed for general‑purpose power applications. It delivers 2200 µF capacitance at an 80 V rating in a compact φ22 × 40 mm can with radial snap‑in mounting.

This part emphasizes lasting performance under elevated temperature and continuous ripple stress, offering 3000 hours endurance at 105°C and significant low‑ and high‑frequency ripple current capability for demanding DC filtering and smoothing tasks.

Key Features

• Capacitance & tolerance — 2200 µF (2.2 mF) with ±20% tolerance (measured at 120 Hz, 20°C), suitable for bulk energy storage and smoothing.
• Rated voltage — 80 V DC rating for higher‑voltage DC link and intermediate bus applications.
• Mounting / package — Snap‑in terminal radial can (φ22 × 40 mm) for fast, secure chassis or board mounting; supplied in tray packing for assembly handling.
• High temperature endurance — Endurance of 3000 hours at 105°C when subjected to rated ripple current, designed for sustained operation in elevated ambient conditions.
• Ripple current capability — Low‑frequency ripple current 2.09 A at 120 Hz and high‑frequency ripple current 2.404 A at 50 kHz, enabling effective filtering across a range of ripple spectra.
• Loss and leakage — tan δ (DF) ≤ 0.20 measured at 20°C, 120 Hz; leakage current specified at 1250 µA after standard test conditions.
• Operating temperature — Rated for −40°C to +105°C operating range to support a wide array of environments.
• Compliance — RoHS‑compliant construction.

Typical Applications

• General‑purpose DC filtering — Bulk filtering and smoothing in power supplies and DC link circuits where an 80 V rating and high capacitance are required.
• Power conversion — Energy buffering and ripple attenuation in converters and intermediate bus stages that impose continuous ripple current at elevated temperatures.
• Industrial electronics — General‑purpose use in industrial control and power modules that require durable capacitors with snap‑in mounting for robust assembly.

Unique Advantages

• Rated for elevated‑temperature duty — 3000‑hour endurance at 105°C under rated ripple current supports long service intervals in hot operating environments.
• Broad ripple performance — Specified ripple currents at both 120 Hz (2.09 A) and 50 kHz (2.404 A) provide predictable filtering behavior across low and high frequency components.
• Compact high‑voltage option — 2200 µF at 80 V in a φ22 × 40 mm can offers high capacitance density for space‑constrained designs.
• Installation‑friendly termination — Snap‑in radial can simplifies mechanical retention for chassis or PCB mounting and supports standardized assembly workflows.
• Measured loss and leakage data — tan δ ≤ 0.20 (20°C, 120 Hz) and specified leakage current help engineers predict dissipation and standby losses.
• RoHS compliance and tray packing — Environmentally compliant and supplied in trays for handling and process compatibility.
