LAN Filter Module Readied For Military Assignments

Protecting 10/100 Base-TX circuitry at temperatures ranging from -40°C to +85°C, the NT805T series LAN filter module is compatible with the industry’s most common transceiver chipsets for military networking environments. It meets PCMCIA, IEEE 802.3, and ANSI X3.263 requirements and is suitable for use in satellite systems, ground transmission and reception stations, and remote instrumentation or test equipment. Features include an insertion loss of -1.1 dB maximum at 1 to 100 MHz, a typical rise time of 2.5 ns from 10% to 90%, and a typical return loss of -5 dB from 0.1 to 60 MHz and -11 dB from 60 to 100 MHz. Common mode choke rejection ratio is -45 dB from 0.1 to 60 MHz and -40 dB from 60 to 100 MHz. Minimum crosstalk is -40 dB from 0.1 MHz to 60 MHz and -38 dB from 60 MHz to 100 MHz. The module also provides 1.5 kVRMS minimum isolation from chip to cable. Available in both transfer-molded through-hole and SMT packages, prices start at $1.80 each/10K.
