05017 CX12 - CX12LC Only One Name Means ProTek’Tion™ coaxial protector Description The CX12 series is a two stage, hybrid surge protector designed to protect interfacing equipment from induced lightning 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. cx12 Features applications • Compatible with IEC 61000-4-5 (Surge): 24A, 8/20µs, Level 2(LineGnd) Level 3 (Line-Line) • BNC Connection • Low Capacitance • Completely Enclosed Aluminum Housing • Low Clamping Voltage • Nanosecond Response Time • Long Life and Maintenance Free • Finger Safe Connectors • Fully Shielded Case • High Speed Video Camera • Coaxial Ethernet • High Speed Data Lines Mechanical characteristics • Metal Package • Approximate Weight: 161 grams figure 1 transient voltage threat condition figure 2 CX12LC clamping voltage Current - Amps Current - Amps 2K 1K 0 30 20 10 0 0 20 40 60 80 100 120 140 160 0 t - Time - µs 20 40 60 80 100 120 140 160 t - Time - µs 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. 05017.R5 2/11 Page 1 www.protekdevices.com 05017 CX12 - CX12LC Only One Name Means ProTek’Tion™ typical device characteristics MAXIMUM RATINGS @ 25°C Unless Otherwise Specified PARAMETER Peak Operating Line Voltage SYMBOL VALUE UNITS VOP ±12 Volts Operating Line Current IO 200 mA Transient Voltage - 20 kV Transient Current - 8/20µs waveform - 3000 Amps CX12 Frequency Response -3dB - 30 MHz CX12LC Frequency Response -3dB - 200 MHz Operating Temperature TA -40 to 85 °C TSTG -40 to 85 °C - < 10 ns Storage Temperature Response Time ELECTRICAL CHARACTERISTICS PER LINE @ 25°C Unless Otherwise Specified PART NUMBER MAXIMUM LEAKAGE CURRENT typical capacitance r ohms @vop ID µA @ 0v, 1mhz c pF 24 3 5 200 28 10 5 25 MAXIMUM CLAMPING VOLTAGE Line-to-Ground (8/20µs) @ 500A VC volts maximum line throughput resistance CX12 CX12LC installation instructions The CX12 series is designed with a female BNC type connector on both ends for easy installation. Disconnect the video or data line from the sensitive equipment. Insert the CX12 in the line near the AC power outlet of the equipment to be protected. Install a cable in between the CX12 and the equipment to be protected. Attach a ground wire between the case of the CX12 and the equipment AC power ground, or to the coax shield as required. 05017.R5 2/11 Page 2 www.protekdevices.com 05017 CX12 - CX12LC Only One Name Means ProTek’Tion™ typical device characteristics figure 3 pulse wave form IPP - Peak Pulse Current - % of IPP 120 tf 100 TEST WAVEFORM PARAMETERS tf = 8µs td = 20µs Peak Value IPP 80 e-t 60 40 td = t/(IPP/2) 20 0 0 5 C - Capactiance - pF 1,000 10 15 t - Time - µs 20 25 30 figure 4 linear vs non-linear capacitance Industry Standard Low Capacitance TVS Protector 100 ProTek Device 10 05017.R5 2/11 0 2 4 6 8 10 V(OP) - Data Line Operating Voltage - Volts Page 3 www.protekdevices.com 05017 CX12 - CX12LC Only One Name Means ProTek’Tion™ typical device characteristics figure 5 frequency response - cx12 20 dB per Division 0 -20 -40 -80 1Hz 100Hz 10kHz 1MHz 100MHz 10GHz 100MHz 10GHz Frequency figure 6 frequency response - cx12LC 10 dB per Division -5 -15 -25 -35 -45 1Hz 100Hz 10kHz 1MHz Frequency 05017.R5 2/11 Page 4 www.protekdevices.com 05017 CX12 - CX12LC Only One Name Means ProTek’Tion™ package information outline dimensions inches NOMINAL NOMINAL A 30.73 1.21 B 27.94 1.10 C 35.56 1.40 D 27.94 1.10 E 18.29 0.72 F 57.15 2.25 G 18.29 0.72 H 17.78 0.70 I 74.93 2.95 J 82.55 3.25 K 3.81 0.15 A B C D K E LINE millimeters dim Notes 1.
