The PPE blends are characterized by hot water resistance with low water absorption, high impact strength, halogen-free fire protection and low density. This plastic is processed by injection molding or extrusion; depending on the type, the processing temperature is 260–300 °C. The surface can be printed, hot-stamped, painted or metallized.
Oscilloscope OL-1 from 1954, the company's first with a relatively small 3-inch CRT which allowed for a highly competitive price of US$ 29.50 (equivalent to $335 in 2023) for the DIY kit. [1] Heathkit is the brand name of kits and other electronic products produced and marketed by the Heath Company.
However, a larger feedback resistance increases the output voltage swing, and consequently a higher gain from the operational amplifier is needed, demanding an operational amplifier with a high gain-bandwidth product. The feedback resistance and therefore the sensitivity are thus limited by the required operating frequency of the transimpedance ...
