Technical Specifications

The center frequency of TB0212A is 433.92 MHz, typical for ISM band applications. The insertion loss is typically 1.5 dB. The passband ripple is very low, which ensures good signal fidelity. The filter provides excellent attenuation at frequencies outside the passband, which helps to reject unwanted signals. It operates over a temperature range from -40°C to +85°C. The package is a small surface mount device (SMD), suitable for automated assembly.

The sharp rejection characteristics of the TB0212A ensure that only the desired frequencies pass through the filter, minimizing interference and improving the overall performance of the wireless system. The low insertion loss helps to maintain signal strength, which is critical for reliable communication. Its stable performance over temperature variations ensures consistent operation in diverse environments.

The TB0212A's compact size makes it ideal for use in portable devices and other applications where space is limited. Its high reliability and long-term stability ensure that it will provide consistent performance over the life of the product.
