Additional Details

The F5KB881M5B4ED-Z operates at a center frequency of approximately 881 MHz. It is designed for a 50-ohm impedance environment. Key specifications include insertion loss (typically around 1.5-2.5 dB), passband width (optimized for the target application), and attenuation in the stopband (high attenuation to reject unwanted signals). The filter's temperature coefficient is carefully controlled to ensure stable performance over its operating temperature range. This part is commonly used in cellular band filtering applications.
