FF0250J

The FF0250J is designed as one kind of 7-pole elliptical function low pass filter device that is similar to a type which has been successfully used in Broadcasting for many years but is offered in a small size and at a reduced cost. And this device is corrected for group delay distortion over 95% of the passband and for loss distortion over the entire passband.

The electrical characteristics of the FF0250J can be summarized as:(1)End of Passband: 2.50 MHz;(2)Nominal 3 dB: 2.68 MHz;(3)Start of Stopband: 3.32 MHz;(4)Group Delay Ripple: 40 ns;(5)Delay Time: 1043 ns.

The other data of this device can be summarized as:(1)Impedance 75 ohms; (2)Insertion Loss < 1.0 dB; (3)Stopband attenuation wrt 100 kHz > 45 dB; (4)Amplitude ripple in passband < 0.2 dB; (5)Video performance for filters of 5.0 MHz (4.5 MHz for 525 line) and above.; (6)Pulse and bar: K - rating < 0.5 %; (7)Luminance/Chrominance Gain inequality (20T) < 2 %; (8)Luminance/Chrominance Delay inequality < 10 ns; (9)Aqueous Washable No. If you want to know more information such as the electrical characteristics about the FF0250J, please download the datasheet in www.seekic.com or www.chinaicmart.com.
