Product Description
Product Overview
The LGN series aluminum electrolytic capacitors are designed for high-reliability applications, featuring snap-in terminals and a 105C temperature rating. These capacitors offer a smaller case size compared to the LGU series, making them suitable for space-constrained designs. They are rated to withstand 3000 hours of rated ripple current at 105C and comply with the RoHS directive (2011/65/EU, (EU)2015/863). The series includes an expanded voltage range up to 600V, providing greater design flexibility.
