The ECS-45K7.5B is a four-pole monolithic crystal filter with a center frequency of 45.0 MHz, designed for intermediate frequency filtering in telecommunications applications. It features a 3 dB bandwidth of ±3.75 kHz, insertion loss of 1.0 dB max, passband ripple of 4.0 dB max, and stopband attenuation of 80 dB at ±910 kHz. The filter uses a UM-1 x 2 package with a terminating impedance of 350//6.5 ohms/pF and operates over a temperature range of -20 °C to +70 °C. It is RoHS compliant.
ECS Inc. offers a wide selection of monolithic crystal filters (MCFs) in both through hole and surface mount design (SMD) packages. These packages feature a broad range of center frequencies, including 10.7 MHz, 21.4 MHz, 45.0 MHz, 70.0 MHz and 90.0 MHz.
The monolithic quartz crystal filter offers the stability of a quartz timing device ideal for intermediate frequency filtering. The monolithic crystal design is both cost-effective and space-saving, which is ideal for today’s wireless and telecommunications applications. Through hole filters come in a variety of sizes, which are application-dependen
