2026-40-C2LF Description

Short technical summary and product information.

The Bourns 2026-40-C2LF is a 3-pole gas discharge tube (GDT) from the 2026 series, designed for overvoltage protection. It has a nominal DC sparkover voltage of 400V with ±20% tolerance, and typical impulse sparkover voltages of 675V at 100V/µs and 925V at 1000V/µs. The device can handle impulse discharge currents up to 20kA (8/20µs, 10 operations) and 5kA (10/350µs, 1 operation). It also has a maximum alternating discharge current of 130A RMS (11 cycles).

 

The GDT features a low capacitance of less than 2pF at 1MHz and high insulation resistance greater than 10 GΩ at 100V. The glow voltage is typically 70V and arc voltage is typically 10V. The impulse transverse delay is less than 75ns. It operates over a temperature range of -40°C to +90°C.

 

This 3-pole device is packaged in an axial cylinder with radial leads for through-hole mounting. It is UL recognized. The datasheet indicates a RoHS compliant version is available.
