The component has a nominal impedance of 50 Ohms and is housed in a 1206 (3216 Metric) surface mount package. It functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• Provides signal conditioning via band pass filtering characteristics for RF applications
• Utilizes ceramic construction for stable performance in communication equipment
• Designed for surface mount installation using the 1206 package format

Applications

• RF communication equipment signal conditioning
• WLAN and Bluetooth module integration
• 2.45 GHz frequency band filtering

Procurement Notes

Verify the specific datasheet version and RoHS compliance status directly with Murata Electronics or authorized distributors before procurement. Confirm that the 1206 package dimensions align with your PCB footprint requirements. Ensure the operating temperature range meets your environmental specifications. Check for any recent product discontinuation notices or lifecycle changes associated with this part number.

Selection Notes

Select this component when a 2.45 GHz center frequency and 50 MHz bandwidth are required for band pass filtering. The 50 Ohm impedance matches standard RF transmission lines. The 1206 SMD package facilitates automated assembly. Consider the -40°C to +85°C temperature range for industrial or commercial environments requiring ceramic filter stability.

Part Context

This part belongs to Murata's LFB series of ceramic filters, which are engineered for RF signal conditioning in wireless communication devices. The series typically offers high Q-factor performance and compact footprints suitable for modern electronics. These filters are distinct from low-pass variants like the LFL series, focusing specifically on band pass applications at designated center frequencies.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative Murata band pass filters by matching center frequency, bandwidth, impedance, and package size.
