Ceramic Filters (CERAFILr)/Ceramic Discriminators for Communications Equipment 1 CERAFILr kHz SMD Type SFPKA Series 7.50.3 The SFPKA series is comprised of small, high performance, economical, thin (5.0mm) filters consisting of 4 ceramic elements. Their innovative construction is perfect for shrinking mobile communication products such as cordless phones, pagers and transceivers. MARKING EIAJ CODE 5.0 max. 0.90.1 2.00.3 1.50.3 2.00.3 Features Center 6dB Frequency (fo) Bandwidth (kHz) (kHz) Stop Bandwidth (kHz) 1.50.3 1.60.3 Connection (1) : Input (2) : Ground (3) : Output (1) (2) (3) 1. The filters are mountable by automatic placers. 2. The filters can be reflow soldered and withstand washing. 3. They are slim, at only 5.0mm maximum thickness. 4. The bandwidth ranges from D to H. 5.
