0℃~+70℃ 1.2214V~1.2586V 100mA Adjustable Parallel ±1.5% SOT-23 Voltage Reference ROHS
The CJ432 is a voltage Reference made by WEIDA in a SOT-23 package with 3 pins. 0℃~+70℃ 1.2214V~1.2586V 100mA Adjustable Parallel ±1.5% SOT-23 Voltage Reference ROHS.
PCBKit's library has its KiCad symbol (Reference_Voltage:CJ432, from KiCad's library) and its footprint (Package_TO_SOT_SMD:SOT-23, from KiCad's library), ready for a KiCad board. 1,682 are in stock at JLCPCB (part C22437007). 5 open-source boards in 5 repositories on GitHub use it.
