Ex workshop spare parts and small manufacturing stock
ALL devices have been sourced through reputable local distributors such as RS Electronics, Farnell, WES and Rockby (Victoria) NOT direct import Chinese (often dodgy spec) devices
These are NEW transistors but tested for Hfe values in preparation for audio equipment production use
FAIRCHILD - Transistor (Gain Tested)
Type: MPS A42
Small signal (particularly audio)
High voltage capable (300V)
Si NPN
300V
Full part # on package
Details details ... serious engineering often will specify EXACT manufacturers product (not all transistors are created equal) and here are the specific manufacturer and batch code information for these A42's.
These transistors have been individually tested by production staff and then stored in packs based on their hFE measurement (β)
Below is a list of the different hFE values and the respective quantity in brackets, I will supply quantities less than one pack - just specify which hFE values you would like
