Ceramic Low Pass Filter LFCG-490+ 50 DC to 490 MHz The Big Deal Very good rejection, 45 dB typical Generic photo used for illustration purposes only Rugged, ceramic construction CASE STYLE: GE0805C-2 Tiny size, 0.079 x 0.049 x 0.037 (0805) Good power handling, 3.5W Product Overview Mini-Circuits LFCG-490+ is an LTCC low pass filter with a passband from DC to 490 MHz, supporting a variety of applications. This model provides 1.5 dB typical passband insertion loss and provides a very good stopband rejection due to strategically constructed layout with minimal interaction between components. It handles up to 3.5W RF input power and provides a wide operating temperature range from -55 to +125C. Housed in a tiny 0805 ceramic form factor with wraparound terminations, the filter is ideal for dense PCB layouts and with minimal performance variation due to parasitics. Key Features Feature Advantages The LTCC lowpass filter provides a very good stopband rejection until 8.5 GHz suitable for high end Ultra-wide stopband applications. Provides repeatable performance in a rugged, ceramic package well suited for tough environments LTCC Construction such as high humidity and temperature extremes. Tiny size (0.079 x 0.049 x 0.037 ) Saves space in dense circuit board layouts and minimizes the effects of parasitics. Good power handling, 3.5W Supports a wide range of system power requirements. Wrap-around terminations Provides excellent solderability and easy visual inspection Notes A.
