T= Tuned model**

**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.

Notes:

1. Mechanical tolerances:

x.xxx in. = ± 0.005 in.

x.xx in. = ± 0.01 in.

2. Pin material: brass with tin/lead plating over nickel

3. Workmanship: Meets or exceeds IPC-A-610B Class II

4. "A" = 0.040" dia. pins

5. "B" = 0.060" dia. pins

6. Min. screw length for heatsink attachment

= 4.5mm + heatsink flange + locking hardware.
