** T (Tuned Model) Option
Designed for higher di/dt and ∆l
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 minmum
3X improvement in the peak response
compared to a standard unit.
