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.
