The company was founded in 1974 in Fairfield, New Jersey as a manufacturer of High-Q, temperature compensating Multi-Layer capacitors. We quickly realized that carefully crafted Single-Layer capacitors were superior to Multi-Layer devices for many higher frequency applications and this was the beginning of the DiCap® product line. It also spawned the basic philosophy that drives DLI today, "deliver innovative products that enhance customers products". In 1977, the company moved to the current site.
