 | Refrigeration Motors and Motor Efficiencies

 | Consolidation, or Better Design?
Sometime around 1920, so my grandmother said, it was believed that everything that could be invented had been. An explosion of consumer goods in that decade had made everything from telephones to toaster ovens to vacuum cleaners and automatic washing machines—things nobody had even heard of a few decades earlier—must-own items for every respectable household.

 | TDK-EPC
New MKP and MKT film capacitors with low insertion heights
have a lead spacing of 37.5 mm feature insertion heights of only 15 or 19 mm.
The components are designed for rated voltages of between 63 and 2000 V DC or
250 to 400 V AC. Their capacitance ranges from 0.1 to 82 µF. Depending on type
and technology (MKT or MKP), these capacitors are designed for maximum
operating temperatures of 105, 110 or 125 °C. Visit www.epcos.com/film_capacitors
