42 | page dimensions in inches (millimeters) cotomos C237S/c337s when small size and high performance are needed, the sop package, such as the C237S or c337s, is the industry choice. both the C237S and the c337s feature low on resistance fast turn on time. in addition, the c337s ofers two fully-independent form a channels for further space savings. both relays are ideally suited to the needs of test and measurement, industrial, and telecommunications.
