**T (Tuned Model) Option
Designed for higher di/dt and
∆I
applications, the
transient response has been modified to take
advantage of the capacitance on the customer's
PCB. This unit requires a minimum load
capacitance of 5600µF with an impedance
magnitude of less than 0.005Ω at 15kHz. It offers a
minimum 3X improvement in the peak response
compared to a standard unit.
