Webasto Air Top 5000 installation.

Pablo,
I looked @ the Webasto site and for me the Thermo 90 st
would best suite my needs. That being said, the price was
$2,600.00 not including install. 1) I believe it to be worth it,
opinions? 2) Could i/ would I want to install myself....
Very capable with anything mechanical. Thanx in advance

 

Thanks for the info. I guess Vishay Dale is the correct manufacturer?
Can anyone tell med what the smd form factor of the 1R0 resistor is?
I can only find resistors with solder strips on the short ends, as opposed to on the long ends.

 

What would be a reasonable temperature coefficient for this purpose?
I can buy a 2 ppm/K resistor for $40/piece, or there is 50 ppm/K units for $0.1/piece.

The correct form factor with soldering point on the long side seems to be hard to get over here in Europe :-/
What about an axial resistor covered with thermal glue?

 

Compare picture below. After this repair the Thermo top C has been working perfectly for a month now. I could'nt get an SMD resistor, had to to a quick repair.

Removed the old resistor, placing a 100W soldering iron transversely on top of it and lifting it with a knife. Soldered in a "traditional" 1 Ohm metal film resistor (1%, probably 0,25W).

 

Just for info, my Thermo Top C is now running perfectly again!
I replaced the faulty 1R0 SMD resistor with a standard 0,4W 1R0 one.
Thanks for tips

 

By the way, have another Thermo Top C with a faulty NTC temp. sensor.
Anyone happen to know the specs on that one?
Thanks!
