LGUW6221MELC

The LGUW6221MELC is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LGU series, rated at 220 µF and 420 V with ±20% tolerance. It is a general‑purpose, radial can capacitor designed for applications that require high voltage capability, robust ripple current handling, and long endurance at elevated temperatures.

Key performance attributes include a low dissipation factor (tanδ 0.15 at 20°C/120 Hz), high ripple current capability, a 3000‑hour endurance rating at 105°C, RoHS compliance, and tray packing for production volumes.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance with a rated voltage of 420 V and ±20% tolerance for high‑voltage DC applications.
• Terminal & Package — Snap‑in terminal, radial can (snap‑in) package for secure board mounting in power assemblies.
• Endurance & Temperature Range — Rated for 3000 hours at 105°C; operating temperature range −25°C to +105°C.
• High Ripple Current Handling — Rated ripple current: 1.1 A at 120 Hz (low frequency) and 1.573 A at 50 kHz (high frequency), supporting demanding ripple environments.
• Low Loss & Leakage — Tanδ 0.15 (max) at 20°C/120 Hz and specified leakage current of 910 µA for predictable electrical behavior.
• Production & Compliance — Tray packing and mass production availability; RoHS compliant.
• Compact Size — Size: φ35 × 25 L (3.5 × 2.5 cm), offering a compact footprint for high‑voltage designs.

Typical Applications

• General‑purpose power filtering — Bulk smoothing and energy storage in general‑purpose power circuits where 420 V rating and substantial capacitance are required.
• High‑temperature power assemblies — Circuits that require sustained operation at elevated temperatures, taking advantage of the 3000‑hour endurance at 105°C.
• Snap‑in board assemblies — Power modules and assemblies that benefit from radial, snap‑in mounting for secure, production‑friendly installation.

Unique Advantages

• High voltage capability: 420 V rating provides headroom for high‑voltage DC applications.
• Long operational life at elevated temperature: 3000 hours endurance at 105°C supports reliable performance in demanding thermal environments.
• Robust ripple handling: High ripple current ratings at both low and high frequencies reduce thermal stress and extend service life in ripple‑heavy circuits.
• Controlled dissipation and leakage: Low tanδ (0.15) and specified leakage current enable predictable AC loss and standby behavior.
• Production ready: Tray packing and mass production status simplify procurement and assembly for volume builds.
• Regulatory compliance: RoHS compliant for environments that require restricted‑substance adherence.
