Don’t get burned about LED UV
Another myth busted: You needn’t worry about ultraviolet light coming from ordinary LED bulbs. We recently checked a batch of LED bulbs for the amount of blue light they gave off. This effort came in response to claims from some in the alternative medicine crowd that LED bulbs gave off inordinate amounts of unhealthy blue […]
New 1.2-kV SiC Schottky diodes feature more creepage and clearance
Wolfspeed, a Cree Company, has expanded its C4D family of 1200V SiC Schottky diodes to introduce three new products in a TO-247-2 type package. The increased spacing between the two leads provides more than twice the creepage and clearance distance compared to standard TO-247-3 and TO-220-2 packages. “Improved creepage distance makes the C4D family expansion […]
