Rated for a maximum voltage of 75 Vdc, the iDQ has a differential mode attenuation of 63 dB at 300 kHz measured with a 50Ω source and load impedance. The filter measures 50 mm in length, 15 mm in width, with a height of 10.8 mm. The iDQ will operate without forced air cooling in ambient temperatures of -40 to +85ºC.
System level compliance to FCC and CISPR is made easier. A pin is provided for the addition of extra capacitance to further enhance common mode performance. The iDQ has 1500 Vdc isolation from ground, enabling operation in systems where the ground is connected to either the positive or negative input.
