current-sense resistor pulse rating

[DHambley]

I would like to know if anyone knows of a Hi-Reli current sense resistor with test data of continuous pulse ratings. Several of our circuits have pulses in the 100's of KHz range, way beyond the thermal time constant. The average power is 100mW but the power during an individual pulse of a few nanosec's is 5W.
The problem is the reliability engineers at every customer of ours, from Lockheed to Boeing, requires that these parts have test data for pulses, which doesn't exist for many resistor types.
Has anyone had any luck finding a good CSR with pulse data for space use?

Circuit Design forum might help more with this question.
good luck.

Higgler, Yes, that may be true but, I wouldn't think any one outside of engineering for spacecraft would have any help. I'll try to post. I bet I get a lot of nonsense from lurkers.

Let's see.....

Trouble is you have all kinds of 'aerospace' related folks here, relatively few of them electric string type folk,.

You have lots of electric string folks there, some of whom may be aerospace.

...just as I thought. No one in the electrical section could answer the question either. Quite a few "lurker" answers though, which were all worthless.
I found some parts with the test data I was looking for anyhow.
