The 748111009 is a multilayer chip low-pass filter from Würth Elektronik's WE-LPF series. It is designed for the 902-928 MHz frequency band with a center frequency of 915 MHz. Key electrical specifications include a maximum insertion loss of 0.5 dB, a maximum VSWR of 1.5:1, and a minimum attenuation of 30 dB at both 2f0 and 3f0. The filter operates over a temperature range of -55°C to +125°C and is rated for storage conditions of 5°C to 40°C with less than 75% relative humidity.

The component is housed in an 0805 (2012 Metric) surface-mount package with dimensions of 2.00 mm x 1.25 mm and a maximum height of 1.05 mm. It features 8 terminals and is suitable for automated assembly. The filter is RoHS3 compliant, REACH unaffected, and halogen-free per JEDEC JS709B and IEC 61249-2-21. Moisture sensitivity level is MSL 1 (unlimited).

This low-pass filter is intended for general electronic equipment and is not authorized for use in safety-critical applications such as military, aerospace, or medical devices without a specific agreement. Typical applications include harmonic suppression in RF transmitters and receivers operating in the ISM band.
