Similar rated caps made by CDE in the USA are available for less cost at
Mouser. Look for the 381LX series. They also carry a full line of power
resistors including 3 and 5W Metal Oxide.
1-800-346-6873 for a free catalog

NO minimum order and only ACTUAL shipping charges. Three regional
warehouses.
