**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 5600

µF with an impedance

magnitude of less than 0.005

Ω at 15kHz. It

offers a minimum 3X improvement in the peak

response compared to a standard unit.
