LGUW6221MELB

The LGUW6221MELB is a snap‑in terminal aluminum electrolytic capacitor in Nichicon's LGU series, rated 420V with 220µF capacitance and ±20% tolerance. It is designed for general‑purpose applications that require a high‑voltage, high‑temperature electrolytic solution with snap‑in mounting.

Key value propositions include a 105°C performance rating, a long endurance specification (3000 hours at 105°C under rated ripple stress), and a radial snap‑in can package (φ30×35L) for robust board mounting and straightforward installation.

Key Features

• Capacitance & Tolerance — 220 µF nominal capacitance with ±20% tolerance (measured at 120Hz, 20°C).
• High Voltage Rating — Rated for 420 V DC to support high‑voltage applications within the LGU series range.
• High‑Temperature Endurance — Specified to withstand 3000 hours at 105°C when subjected to D.C. bias plus rated ripple current; capacitance change remains within ±20% after the endurance test.
• Operating Temperature Range — –25°C to +105°C for the 315–450V range, matching the product's rated voltage class.
• Defined Ripple Current Performance — Rated ripple current of 1.1 A at 120 Hz and 1.573 A at 50 kHz, with frequency coefficients provided in the series datasheet.
• Snap‑In Radial Can Package — Snap‑in terminal radial can (φ30×35L; L: 3.5 × D: 3 cm) for secure PCB retention and mass‑production assembly (tray packing).
• Endurance & Shelf Life Specifications — Endurance and shelf life requirements are defined in the datasheet (including 1000 hours at 105°C shelf condition with subsequent voltage treatment), ensuring predictable long‑term behaviour.
• RoHS Compliance — Compliant with RoHS directives as specified in the product documentation.

Typical Applications

• General‑purpose power filtering — Use where a 420V, 220µF electrolytic capacitor is needed for general filtering tasks.
• General‑purpose energy buffering — Suitable for general applications requiring high‑voltage energy storage in a snap‑in package.
• General‑purpose smoothing — For general smoothing duties at elevated ambient temperatures up to 105°C.

Unique Advantages

• High‑voltage capability: 420V rating enables use in higher DC voltage environments without changing capacitor topology.
• Temperature‑rated endurance: 3000‑hour endurance at 105°C under rated stress provides predictable long‑term performance in hot operating conditions.
• Snap‑in mounting convenience: Radial snap‑in can offers secure PCB retention for high‑volume assembly and mechanical stability.
• Clear performance data: Ripple current values at 120Hz and 50kHz and endurance/shelf life limits are defined in the datasheet for engineering verification.
• RoHS compliance: Meets RoHS requirements for environmentally regulated designs.
