| A couple
things to keep in mind about these caps.
- The voltage rating of the cap is only really
important if you try to use a cap that is rated below your system.
So do not attempt to use anything with a voltage rating below 15v
for its normal rating. Most caps have a dual rating, but to use the
higher voltage rating other aspects must be met or taken into
consideration. It's not worth messing with.
The capacitance, expressed here in microfarads (uF) was speced at
22uF. I do not know how or where this value was determined, I'm just
trying to provide owners out there some options. All parts listed
here are 22uF. Usually it does not harm anything to have a greater
value, but since this cap is to be used to clean up the electrical
signal to the ECU, I would not try another value. Especially since
this value has been proven to work well.
Tolerance. This value could be important. It basically gives you an
idea of how accurate, or true, the part is. Caps are not exact
creatures and have sway in there values. They are all rated as +/-
X%. So obviously a cap with a smaller tolerance will give you better
results.
Body style. Axial has leads coming out each end of the part. Kind of
like a car axle. Radial has both leads coming out the same side of
the part. Like legs. While neither style will offer a performance
advantage, I would think the radial leaded parts will physically fit
in the location better.

All of the above items can be purchased from a
number of vendors. Most wholesalers of electronic parts do not like to
sell small quantities of parts. But the following online vendors will sell
to you. They may however impose a small minimum purchase amount. Probably
your best bet is to use Digi-Key (
www.digikey.com ) or Newark (
www.newark.com ). You may also have good luck with Allied Electronics
( www.alliedelec.com ), Mouser
Electronics ( www.mouser.com ) and of
course Radio Shack (
www.radioshack.com ). Radio Shack however is not going to use the
manufacturer's part numbers in this list. You will have to search through
their stuff for the values you want. |
