Dale Electronics was founded in 1950 in Columbus, Nebraska, USA. It quickly became the gold standard (MIL-SPEC) for the aerospace and military industries, thanks to its nearly indestructible wirewound resistors. In 1985, Vishay Intertechnology acquired Dale. Today, components with the classic Dale tubular format are synonymous with old-school military and industrial reliability.<\/p>\n(FAQ)<\/span><\/h3>\n
A: Not at all. The wear is purely cosmetic, caused by contact with other components during storage. The internal wirewound element remains intact and has been verified with a precision multimeter to ensure an accurate 1.5-ohm resistance value.<\/p>\n
A: Yes. To operate this resistor continuously at its full 225W rating, proper thermal management is essential, such as a suitable heatsink or forced-air cooling, due to its high power density in a compact 61\u00ed\u201428 mm form factor.<\/p>\n
A: Yes, as long as the circuit requires the exact 1.5-ohm specification and has sufficient space and thermal management to accommodate this 225W model.<\/p>\n","protected":false},"excerpt":{"rendered":"
