Hi
Well…..
Once upon a time, there was a design review on a space part. There
was an tantalum cap used in a couple of places in the design. It was
a 50V part and running at 12V.
We got dinged for it. Turns out if you over derate electrolytics (of any sort)
there is a failure mechanism that
I've just released an update to the Arduino firmware for the TICC; the
new version is 20200412.1. It, along with all the TICC source code and
documentation, is available at:
https://github.com/TAPR/TICC.
In addition to a few bug fixes and cleanups, there are a couple of more
noticeable changes
Hi
Electrolytic caps have a lot of leakage. That’s the bad news. The good news is
that if you maintain a stable voltage on a tantalum part, the leakage decays
( = drops off) with time. In a system with a fixed EFC, you probably can get
away
with a tantalum part. You will have to wait a bit for
Speaking of high-performance crystal oscillators, EFC inputs and Tantalum
capacitors, how to select a good decoupling capacitor for its EFC input?
I'm attaching two PN measurements made yesterday on a HP3048A. There are
two 100MHz crystal oscillators in the setup, (1) a XCO made by myself,
which
Unwind a foot or so of wire and measure the resistance to figure the wire
size. If possible, then unwind the entire choke to find its proper
resistance. This will determine the original value from the inductor data
sheet. If not calculate the resistance from the volume of the winding.
