2026-42-C2LF Description

Short technical summary and product information.

The Bourns 2026-42-C2LF is a 3-pole gas discharge tube (GDT) from the 2026 series, designed for overvoltage protection in telecommunications and industrial equipment. It features a DC sparkover voltage of 420V with ±20% tolerance and a high impulse discharge current rating of 20kA (8/20µs waveform).

 

The GDT provides stable breakdown characteristics throughout its life, with typical impulse sparkover voltages of 725V at 100V/µs and 1000V at 1000V/µs. It offers low capacitance of less than 2pF at 1MHz, making it suitable for high-speed signal line protection. The device operates over a temperature range of -40°C to +90°C.

 

Packaged in an axial cylinder with three radial leads for through-hole mounting, the 2026-42-C2LF is RoHS compliant and has an MSL rating of 1 (unlimited). It is UL recognized and meets ITU-T K.12, IEEE C62.31, and IEC 61643-311 GDT standards.
