• High‑temperature rating: Rated for operation up to 105°C, with category temperature range specified for 350–600 V parts covering –25°C to +105°C.
• Long endurance: Withstands 3000 hours of rated ripple current application at 105°C per LGN series endurance criteria.
• Robust ripple current performance: Rated ripple current of 1.23 A at 120 Hz and 1.759 A at 100 kHz, supporting demanding AC ripple conditions.
• Snap‑in radial can package: Snap‑in mounting for secure board retention and straightforward assembly in power electronics assemblies.
• Polarized, ±20% tolerance: Polarized device with capacitance tolerance of –20% to +20% at 120 Hz, 20°C.
• Compact footprint: Smaller case sizing relative to the LGU series while providing similar LGN series performance characteristics; physical size L: 5 × D: 2.5 cm.
• RoHS compliant: Conforms to RoHS directive requirements (2011/65/EU, (EU)2015/863).

Typical Applications

• High‑voltage power filtering — General‑purpose DC filtering where 450 V rating and 270 µF capacitance are required to smooth power rails.
• Power conversion and conditioning — Use in general‑purpose power electronics requiring sustained ripple handling at elevated temperature.
• Industrial equipment — Suitable for general‑purpose industrial assemblies that demand 105°C rated electrolytic capacitors with snap‑in mounting.

Unique Advantages

• Proven high‑temperature endurance: Specified to withstand 3000 hours under rated ripple at 105°C, delivering predictable life under thermal stress.
• High voltage capability: 450 V rating enables use in elevated DC link and high‑voltage circuits while maintaining compact capacitance.
