237C

237C is a designation that can refer to several distinct entities, most notably a specific type of transistor and a location within the United States. In the realm of electronics, 237C often designates a bipolar junction transistor, specifically an NPN type. These transistors are commonly used in amplification and switching circuits. The '237' part of the designation typically indicates a series or family of transistors, while the 'C' might denote a particular variation within that series, possibly related to its gain (hFE) or other electrical characteristics. Information regarding the exact specifications and applications of a 237C transistor would be found in its manufacturer's datasheet.

Beyond electronics, 237C is also a designation for a specific block within the United States census system. This refers to census tract 237 in certain counties and states. Census tracts are small, relatively stable statistical subdivisions of a county, generally having between 1,200 and 8,000 persons, designed for the purpose of presenting statistical data. Therefore, 237C in this context would represent a particular geographic area for the collection and dissemination of demographic and socioeconomic information.
