Tiny surge arrester
26 November 2008, Circuit & System Protection
Epcos has developed what it claims is the world’s smallest leaded gas-filled 2-electrode arrester.
With a length of 3,5 mm, it has a diameter of just 2,8 mm. The G3 arrester series is available with response voltages ranging from 75 to 600 V d.c. Despite its tiny dimensions, it can withstand surge currents of 2 kA with an 8/20 μs ripple and features an insulation resistance of more than 1 G.
The parasitic capacitance of this arrester is less than 0,5 pF at 1 MHz, making it well suited for use in data and telecommunications technology as well as for applications with a high packing density of components. |
