coaxial protector
CX12 - CX12LC
Description
The CX12 series is a two stage, hybrid surge protector designed to protect interfacing equipment from induced light-
ning or switching transients. The multistage technique has proven to be the most cost effective and reliable method
for protecting sensitive electronic equipment. Employing state-of-the-art avalanche junction diode technology, these
devices provide superior performance for video, Ethernet, Token Ring or other LAN interface systems. They are in-line
modules with easy interconnecting terminals. A completely enclosed aluminum housing provides EMC shielding to
meet industry standard requirements. The enclosure has two female BNC type connections for easy installation. The
case is grounded for those installations that require external ground connections.

Figures 1 and 2 are photographs of digitized waveforms showing the typical clamping action of a CX12LC module. The device was subjected to a
2000A, 8/20µs impulse waveform in accordance with ANSI C62.36. The CX12 has an operating frequency range up to 10MHz and the CX12LC has
an operating frequency range up to 100MHz.
