Low Cost Axial VactrolsVTL5C3, 5C4PACKAGE DIMENSIONS INCH (MM)PLASTIC POTTING CONTOUR NOT CONTROLLEDDESCRIPTION VTL5C3 has a steep slope, good dynamic range, a very low temperature coefficient of resistance, and a smal light history memory. VTL5C4 features a very low “on” resistance, fast response time, with a smaller temperature coefficient of resistance than VTL5C1.
