Bourns, Inc. Gas Discharge Tube Arresters (GDT) 2027-47-BLF

The 1030207-2027-47-BLF is a Gas Discharge Tube (GDT) arrester designed for circuit protection applications. It features a DC sparkover voltage of 470 V with a tolerance of ¬±15%. This model is part of the 2027 series, which is recognized for its high surge current rating, capable of handling an impulse discharge current of 10,000 A (10 kA) for 8/20 Oºs pulses. The device operates with two poles and is suitable for through-hole mounting in an axial cylinder package. The GDT has an insulation resistance greater than 10^10 Oc and a low capacitance of less than 1 pF at 1 MHz, making it suitable for high-frequency applications. It can withstand operating and storage temperatures ranging from -55 ¬8C to +125 ¬8C. The product is UL recognized and complies with RoHS directives, ensuring it meets environmental standards. Engineers considering this component should note its stable breakdown characteristics throughout its lifespan and its ability to protect without venting after discharge, making it a reliable choice for telecommunications, industrial, and consumer electronics applications.
