I've had a similar experience with failing electrolytic aluminum can caps. Interesting in that all the failures have been in aluminum radial leaded caps. Never have had a failure of axial le ...

My very basic test rig with somewhat empirical results- no measured data.

Objective: observe failure of fusible links of various lengths when subjected to a high current short circuit event.

Aha! That's a whole different problem. If I'm reading ElectroAir literature correctly, that input of bus (SNIP) A short on that feeder would be limited to 600 mA or le ...

This discussion is the result of the addition of two E-mags to the current RV project and reviewing the Emag installation instruction. They call for a c ...

The Delphi spec does not indicate length. Really is' material properties not performance characteristics.

I will do a couple of tests with varying "link" lengths using a fully char ...

Back to the original question of the length of a fusible link. That is the length of smaller gauge wire comprising the 'link'.

The premise being that a dead short of the fusible link prote ...

In re-reading the AeroElectric connection section on fusible links, you refer to 3" to 6" length for the fusible section. Why can they not be, say 1" in length? Mostly concern for ...

Bob,Excellent info. I'm a bit smarter now, a good thing! As are others reading this!

Bob, Thanks for the info. I have lots of 50Ω terminations from the old coax network days. But not designed for high power.The item you referred is exactly what I need!

The load has to dissipate the power which is quite high I believe. An inductive load I don't think is advisable.

What is the appropriate type load to apply as a dummy in place of an antenna to test operation of a transponder?

All good points and I appreciate your confirmation and critique.

Huber+Suhner(Mouser) lists weights asRG-400 6.4 kg/100m
RG-316 1.6 kg/100m

RG-400 is 4x the weight of RG-316

I would hope that the weight of cable is consistent between manufacturers.

RG-316: Max power at 1.05 GHz is 125 Watts (I am using RG-400 for Xponder). ~350 Watts max power at comm frequencies. Attenuation at 0.15 Ghz (nominally comm freq) 0.096 db/ft (RG-400 @ .30 Ghz i ...

Looking at the specs for antenna coax the RG-316 v RG-400, the RG-316 performs as well as RG-400 for the short runs and RF frequencies used in our OBAM aircraft. The RG-316 is 1/4 the weight/ft as ...

There is a self powered vibration sensing stand alone Hobbs meter. I have on, after 20 years it still continues to count hours.

I think ENM makes one and I wonder if there is a vibration sensor t ...
