Additional Details:

The B39431R860H210 is designed for specific frequency ranges, typically in the MHz or GHz bands, depending on the application requirements. The filter's insertion loss is typically less than 2 dB, ensuring minimal signal attenuation. The attenuation of unwanted signals can be as high as 40 dB or more, providing effective filtering. The filter is packaged in a small SMD package, allowing for high-density board layouts. The operating temperature range typically spans from -40°C to +85°C, suitable for a wide range of environmental conditions. EPCOS provides detailed datasheets with specific electrical characteristics, including insertion loss, attenuation, impedance, and temperature coefficients. These datasheets are essential for proper design and integration into RF circuits. The filter is designed to meet industry standards for environmental compliance, such as RoHS.
