FF0250M

The FF0250M is designed as one kind of low pass video filter device that is intended for bandwidth limitation where a fast rate of cut off is required. Also this device is especially useful in removing sound sub-carriers from a video signal while maintaining essential bandwidth and is corrected for group delay distortion over 85% of the passband and for loss distortion over the entire passband.

The electrical characteristics of the FF0250M can be summarized as:(1)End of Passband: 2.50 MHz;(2)Start of Stopband: 2.85 MHz;(3)Group Delay Ripple: 30 ns;(4)Delay Time: 1047 ns.

The other data of the FF0250M can be summarized as:(1)Impedance 75 ohms; (2)Insertion Loss < 2.0 dB; (3)Stopband attenuation wrt 100 kHz > 40 dB; (4)Amplitude ripple in passband < 0.3 dB; (5)Video performance for filters of 5.5 MHz (4.5 MHz for 525 line) and above.; (6)Pulse and bar: K - rating < 1.0 %; (7)Luminance/Chrominance Gain inequality (20T) < 1.5 %; (8)Luminance/Chrominance Delay inequality < 5 ns; (9)Aqueous Washable No. If you want to know more information such as the electrical characteristics about the FF0250M, please download the datasheet in www.seekic.com or www.chinaicmart.com.
