10K ECL Noise Filter Module
The 10K ECL Noise Filter Modules manufactured by Engineered Components Company are designed to filter or
suppress input pulses below a specified suppress pulse width and to pass pulses above a specified pass pulse
width. The operation of this module will eliminate unwanted shorter positive pulses from an input data
stream and produce an output data stream consisting of only the longer positive pulses. The output of the
module will remain “low” for any input pulse times shorter than the suppress time, and will change to a “high”
for pulse times longer than the pass time.
The MTBF on these modules, when calculated per MIL-HDBK-217, for a 50 deg.C ground fixed environment and
with 50VDC applied, is in excess of 1.8 million hours. The temperature coefficient of delay is less than
+/-200 ppm/deg.C over the operating temperature range of -30 to +85 deg. C.
The module is provided in a 16-pin DIP package, fully encapsulated in epoxy resin and is housed in a Diallyl
Phthalate case, blue in color. The case marking is applied by silkscreen using white epoxy paint. The 5 copper
leads are tin-lead plated and meet the solderability requirements of MIL-STD-202, Method 208.
