Additional Details

The B39202-AF36B-P812 SAW filter operates at a specific center frequency (the exact frequency needs to be verified using the TDK datasheet). It features a defined bandwidth and insertion loss characteristic. It is typically a surface-mount device (SMD) for automated assembly. The operating temperature range typically spans from -40°C to +85°C, though this should be confirmed in the datasheet. Detailed specifications, including impedance, bandwidth, and attenuation characteristics, can be found in the product datasheet available from TDK. It is highly likely that this filter is designed for 50 Ohm impedance systems.
