SA050 series

A1, A2, A3 (Cone Angle): A1 is the smallest, A3 is the biggest.
CR ( Curvature Radius): CR50 means tip apex curvature radius is 50nm, total diameter is under 100nm.

Example:

MSCT-SA060TPL015TL03TC025A1-CR20

It means
•SA050 series, Copper diameter is 0.5mm
•Total probe length(TPL)is 15mm
•Tip length(TL) is 3mm
•A1 cone angle type
•Tip apex curvature radius(CR) is 20nm, total diameter is under 40nm
