Surface Mount DIP Tapped Passive Delay Line
The Surface Mount DIP Tapped Passive Delay Lines manufactured by Engineered Components Company are designed to
provide precise and stable delays for analog delay line applications. These tapped delay lines are provided in a
small 14-pin DIP package, available in impedances of 50, 100, and 200 ohms, with 10 equally spaced taps.
These delay lines are designed and tested in accordance with MIL-D-23859 and they are capable of meeting the
environmental requirements of MIL-STD-202 for moisture resistance, vibration, temperature cycling, humidity, and
life. The MTBF on these delay lines, when calculated per MIL-HDBK-217, for a 50 deg.C ground fixed environment
and with 50VDC applied, is in excess of 12 million hours. The temperature coefficient of delay is less than
75 ppm/deg.C over the operating temperature range of -55 to +125 deg. C.
The delay line is fully encapsulated in epoxy resin and is housed in a Diallyl Phthalate case, green in color. The
case marking is applied by silkscreen using white epoxy paint. The 13 beryllium copper leads are tin-lead
plated and meet the solderability requirements of MIL-STD-202, Method 208.
