LGNW6221MELA35

The LGNW6221MELA35 is an aluminum electrolytic capacitor in a snap‑in terminal, radial can package from Nichicon's LGN series. It provides 220 µF capacitance at a 420 V rating and is polarized for general‑purpose power applications.

Designed for high‑temperature operation, this smaller‑sized snap‑in capacitor withstands extended ripple‑current loading at elevated temperature and is RoHS‑compliant, making it suitable for robust industrial and commercial power systems where compactness and thermal endurance matter.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance with a 420 V rated voltage and ±20% tolerance, suitable where mid‑range high‑voltage bulk capacitance is required.
• High‑temperature Endurance — Rated operating temperature up to 105°C with a specified lifetime of 3000 hours at 105°C when subjected to rated ripple current and DC bias.
• Ripple Current Performance — Specified ripple current capability of 1.05 A at 120 Hz and 1.502 A at 100 kHz, supporting AC ripple handling across low and high frequency ranges.
• Compact Snap‑in Package — Radial, can‑style snap‑in terminal mounting that delivers secure PCB retention; the LGN series offers one rank smaller case sizing than the LGU family for tighter board layouts.
• Operating Range & Polarization — Polarized electrolytic capacitor specified for operation from −25°C to +105°C; intended for general‑purpose power use.
• Physical Dimensions — Size approximately L: 3.5 × D: 2.5 cm with a maximum seated height of 1.378 inch, enabling compact placement in power assemblies.
• Regulatory Compliance — Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Power supplies — Bulk smoothing and filtering where 420 V rating and 220 µF capacitance provide energy storage and ripple reduction.
• Industrial power conversion — DC bus support and ripple handling in converters and inverters that require 105°C endurance and sustained ripple capability.
• Commercial electronics — General‑purpose high‑voltage decoupling and energy buffering in systems needing a compact, snap‑in radial can solution.

Unique Advantages

• Extended high‑temperature lifetime — 3000 hours at 105°C under rated ripple and DC bias reduces maintenance and replacement frequency in high‑thermal environments.
• Dual‑frequency ripple capability — Published ripple current ratings at both 120 Hz and 100 kHz help designers evaluate performance across mains and switching domains.
• Space‑efficient case size — One rank smaller case than LGU series supports denser board layouts without sacrificing voltage or capacitance.
• Robust snap‑in mounting — Radial snap‑in terminals provide secure mechanical retention for high‑vibration installations.
• RoHS compliance — Conforms to applicable RoHS directives, easing regulatory acceptance in many end products.
