**T (Tuned Model) Option

Designed for higher di/dt and ∆I applications, the

transient response has been modified to take advan-

tage 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.
