The 05D470K with Varistors 38V 104V 100A Through Hole RoHS manufactured by COV is a cylindrical component with 2 leads, measuring 5mm in diameter and 4.7mm in height. It is typically made from alumina oxide or other ceramic-based compounds, depending on the manufacturer and application requirements. The Varistor provides an effective bidirectional voltage clamp by attenuating voltage above and below a set clamp point, allowing for a high degree of electrical protection. This product is RoHS compliant and is rated at 38V – 104V with a current rating of 100A.
