This document describes the features and characteristics of the transistors with built-in resistors UNR4121/4122/4123/4124/412X/412Y, which are suitable for digital circuits. Costs can be reduced through downsizing of the equipment and reduction of the number of parts. The new S type package allows supply with radial taping.
This document is a datasheet for the Panasonic UNR4121/4122/4123/4124/412X/412Y series of silicon PNP epitaxial planar transistors with built-in resistors. The series is designed for digital circuits and features a new S type package allowing supply with radial taping. The datasheet lists specific resistance values for each model, such as 2.2kΩ for the UNR4121 and 10kΩ for the UNR4123.
