Power Resistors in kits
#1
Hi all Tuberionatians!


I noticed that in the kits there are no Power Resistors anymore for local decoupling.


Or so it seems.
Maybe they are rated 1 Watt and I just don't see it.


In earlier times it was advised to raise them above the PCB or circuit card, but I don't see that notice anymore.
Have the resistors become so much cooler?


Also, it was always advised to make a shape with the legs instead of just keeping them straight.
I always wondered what that is about.
I can think of only one scenario:
The Power Resistor gets very, I mean extremely hot in case of some failure.
It melts, no it boils the solder and threatens to do a "melt down": sink down the solder holes onto the board.
There it could make a short if it touches another component on the way down.
Therefore the legs are bent, so that it can not lower itself onto the board.


Kind regards,

Eric-Jan
