Comparison of ni-cr and tantalum nitride film resistors in communication applications
Prior to the widespread acceptance of surface mounted sheet resistors in the 1980s and 1990s, metallized hole mounted molded resistance was usually used in precision applications. Through hole mounted discrete resistors have always been made by depositing thin film resistive materials on cylindrical ceramics. The leads are connected to both ends of the ceramic and the columnar resistance devices are molded or coated to produce a fully sealed product as shown in figure 1. The sheet resistance shown in [...]
