INFORMATION

circuit component values

The TISP61060 is a functional replacement for three devices, the LB1201, TCM1030 and TCM1060. These

devices have a minimum value of series limiting resistor (R1 and R2 in Figure 2) which will ensure that the

impulse surge current will not exceed the device rated value. This is summarised in the table below.

This table shows that the TISP61060 has impulse ratings which are higher or equal to those of the other three

devices. Similarly, the TISP61060 has a.c. ratings which are higher or equal to those of the other three

devices. A series over-current protector should be included in the wire feed to prevent exceeding the
