ACAS 0606 AT, ACAS 0612 AT - Precision

Precision Thin Film Chip Resistor Array

Superior Moisture Resistivity

Vishay Beyschlag

APPLICATION INFORMATION

The power dissipation on the resistor generates a temperature rise against the local ambient, depending on the heat flow support

of the printed-circuit board (thermal resistance). The rated dissipation applies only if the permitted film temperature is not

exceeded. These resistors do not feature a limited lifetime when operated within the permissible limits.
