7 / 78 page Ceramic Filters (CERAFIL r) for Communications Equipment CERAFIL r kHz SMD Type SFPKA Series 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. c Features 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. Operating temperature range: -20 to +80 (°C) Storage temperature range: -40 to +85 (°C) 3.0±0.3 2.0±0.3 1.5±0.3 7.0±0.3 0.9±0.1 MARKING EIAJ CODE 2.0±0.3 (1) (2) (3) 1.5±0.3 1.6±0.3 Connection (1): Input (2): Ground (3): Output (in mm) Part Number Center Frequency (fo) (kHz) 6dB Bandwidth (kHz) Stop Bandwidth (kHz) Stop Band Attenuation (dB) Insertion Loss (dB) Ripple (dB) Input/Output Impedance (ohm) SFPKA455KD4A-R1 455 ±1.5kHz fn±10.0 min. fn±20.0 max.

[within fn±2kHz] 2000 Center frequency (fo) defined by the center of 6dB bandwidth. (fn) means nominal center frequency 455kHz. For safety purposes, connect the output of filters to the IF amplifier through a DC blocking capacitor. Avoid applying a direct current to the output of ceramic filters. The order quantity should be an integral multiple of the "Minimum Quantity" shown in package page in this catalog. Rg+R1=R2=Input/Output Impedance E1: S.S.G.
