LGNW6221MELB30

The LGNW6221MELB30 is a polarized aluminum electrolytic capacitor in a snap‑in radial can package designed for general‑purpose power applications. It delivers 220 µF at a rated 420 V with a compact, smaller‑sized snap‑in form factor and is specified for continuous operation up to 105°C.

Built to the Nichicon LGN series endurance profile, this part targets power supply filtering, smoothing and energy storage in industrial and electronic equipment where elevated temperature endurance and high ripple handling are required.

Key Features

• Rated Capacitance and Voltage — 220 µF capacitance at a 420 V rated voltage for high‑voltage filtering and energy storage.
• Snap‑in Radial Can Package — Snap‑in terminal mounting for secure mechanical retention in power assemblies and capacitor banks.
• Compact, Smaller Case Size — One rank smaller case size than LGU, providing a reduced board footprint while maintaining high performance.
• High Temperature Endurance — Specified for operation to 105°C with a guaranteed lifetime of 3000 hours at 105°C under DC bias plus rated ripple current.
• Ripple Current Capability — Rated ripple current of 1.05 A at 120 Hz and 1.502 A at 100 kHz to support heavy AC stress in power circuits.
• Electrical Stability — Capacitance tolerance ±20% and tan δ maximum 0.15 for rated voltages up to 420 V; endurance limits cap change to within ±20% after the specified life test.
• Wide Operating Range — Operating temperature range of −25°C to +105°C appropriate for 350–600 V class parts in the LGN series.
• RoHS Compliant — Meets RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Power Supply Filtering — Bulk and smoothing capacitors in high‑voltage DC rails where 420 V ratings and high ripple handling are required.
• Industrial Power Electronics — Energy storage and DC link use in power conversion equipment that sees elevated ambient and operating temperatures.
• Capacitor Banks and Power Modules — Snap‑in mounting simplifies assembly into multi‑capacitance banks and rack‑mounted power assemblies.

Unique Advantages

• Proven High‑Temperature Endurance: 3000 hours at 105°C under rated ripple/voltage conditions provides predictable aging characteristics for long‑life designs.
• High Ripple Handling: Specified ripple currents at both 120 Hz (1.05 A) and 100 kHz (1.502 A) support designs subject to substantial AC stress.
• Space‑Saving Mechanical Design: One rank smaller case size than LGU allows more compact assemblies without sacrificing rated voltage or capacitance.
• Predictable Post‑Endurance Performance: After endurance testing, capacitance remains within ±20% and tan δ remains within specified limits, aiding reliability forecasting.
• RoHS Compliance: Meets current EU RoHS requirements for use in regulated markets.
