Ceramic Low Pass Filter 50Ω LFCN-8440+ DC to 8440 MHz The Big Deal • Rugged, ceramic construction • Tiny size, 0.12 x 0.06 x 0.04” • Excellent power handling, 8W CASE STYLE: FV1206-4 Product Overview Mini-Circuits’ LFCN-8440+ is an LTCC low pass filter with a passband from DC to 8440 MHz, supporting a variety of applications. This model provides 1.3 dB passband insertion loss and 30 dB typical stopband rejection. It handles up to 8W RF input power and provides a wide operating temperature range from -55 to +100°C. Housed in a tiny 1206 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 LTCC Construction Provides repeatable performance in a rugged, ceramic package well suited for tough environments such as high humidity and temperature extremes. Tiny size (0.12 x 0.06 x 0.04”) Saves space in dense circuit board layouts and minimizes the effects of parasitics. High power handling, 8W Supports a wide range of system power requirements. Wrap-around terminations Provides excellent solderability and easy visual inspection Wide operating temperature range, -55 to +100°C Enables reliable performance in extreme environments. Notes A.
