The PRODUCT TECHNICAL INVENTORY SAMPLES CONTACT performance delivered in the Bourns GDT25 Series helps to significantly heighten LIBRARY protection against induced voltage transients such as lightning and AC induction. Plus, the enhanced level of protection with tighter voltage limiting provided during fast-rising Agency Recognition events will reduce stress on downstream components compared to current GDT designs in the same application.
