Part description: Edge Card Twin-ax Differential Pair Cable Assy

ATTRIBUTE DEFINITIONS Continued

DIELECTRIC WITHSTANDING VOLTAGE (DWV):

To determine if the sockets can operate at its rated voltage and withstand momentary over potentials due to

switching, surges, and other similar phenomenon. Separate samples are used to evaluate the effect of

environmental stresses so not to influence the readings from arcing that occurs during the measurement

process.

1) PROCEDURE:

a. Reference document: EIA-364-20, Withstanding Voltage Test Procedure for Electrical Connectors.

b. Test Conditions:

i. Between Adjacent Contacts or Signal-to-Ground

ii. Rate of Application 500 V/Sec

iii. Test Voltage (VAC) until breakdown occurs

2) MEASUREMENTS/CALCULATIONS

a. The breakdown voltage shall be measured and recorded.

b. The dielectric withstanding voltage shall be recorded as 75% of the minimum breakdown voltage.

c. The working voltage shall be recorded as one-third (1/3) of the dielectric withstanding voltage (one-

fourth of the breakdown voltage).

LLCR:

1) EIA-364-23, Low Level Contact Resistance Test Procedure for Electrical Connectors and Sockets.

2) A computer program, LLCR 221.exe, ensures repeatability for data acquisition.

3) The following guidelines are used to categorize the changes in LLCR as a result from stressing

a. <= +5.0 mOhms: --------------------------- Stable

b. +5.1 to +10.0 mOhms:--------------------- Minor

c. +10.1 to +15.0 mOhms: ------------------- Acceptable

d. +15.1 to +50.0 mOhms: ------------------- Marginal

e. +50.1 to +2000 mOhms: ------------------ Unstable

f. >+2000 mOhms:---------------------------- Open Failure
