ENW-89846A1KF – PANASONIC

The ENW-89846A1KF, manufactured by Panasonic, is a surface-mount device (SMD) bandpass filter designed for operation centered at 1.8 GHz. This filter utilizes a ceramic resonator technology to achieve a typical insertion loss of 2.0 dB within its passband, which spans approximately 80 MHz. The filter exhibits a minimum attenuation of 25 dB at frequencies 100 MHz above and below the center frequency, providing effective rejection of out-of-band signals. The ENW-89846A1KF is constructed in a compact, low-profile SMD package measuring 3.0 mm x 3.0 mm x 1.5 mm, suitable for high-density PCB layouts. This component is intended for use in applications requiring precise filtering in the 1.8 GHz ISM band, such as wireless communication systems and GPS receivers. It is designed to operate over a temperature range of -40°C to +85°C and has a nominal impedance of 50 ohms.
