BU21050FS-E2 Overview
Packaging consists of materials from Tape & Reel (TR).There is a 32-SOP (0.213, 5.40mm Width) package that is used in order to conserve space.This type of Capacitive Switch is capable of providing superior performance.Surface Mount is used as the mounting method.In order to avoid unnecessary cooling processes, the operating temperature should be kept at -40°C~85°C.Sensor and detector interface uses the input type Logic.The use of 32 terminations is intended to prevent signals from reflecting off the transmission line's end.According to its base part number of BU2105*, related electronic parts are available.In this case, it is configured with 1 functions.There is a voltage supply of 5V that is used to operate it.As an electronic device, it is a 32-pin type.Each 32 component pin is designed for a specific purpose.A Surface Mount mounting is used.Maintaining the operating supply current at 550μA may improve efficiency.The supply voltage will be exceeded by 5.5V and failures will occur.In the case of a lower supply voltage than 4.5V, failures will occur.A 8 channel is designed for the transmission of data.Sensor and detector interface is typically used in applications where the supply voltage is 5V.
