SF1194A

Overview

The SF1194A is a Surface Acoustic Wave (SAW) filter manufactured by Murata Electronics. It operates at a center frequency of 167 MHz with a bandwidth of 150 kHz and an insertion loss of 7 dB. The component is housed in a 10-SMD, no-lead package. It is classified as a general-purpose RF SAW filter.

Feature Summary

• Utilizes Surface Acoustic Wave technology for signal filtering
• Designed for general-purpose radio frequency applications
• Features a compact surface-mount package configuration

Applications

• General purpose RF signal processing
• Frequency selection in communication circuits
• Intermediate frequency filtering in receiver architectures

Procurement Notes

Verify the current production status before procurement planning. Official documentation indicates this part may be obsolete or discontinued. Confirm availability through authorized distributors and check for RoHS compliance status, as sources indicate potential lead content. Ensure the 10-SMD package matches your PCB footprint requirements.

Selection Notes

Select this component only if the specific 167 MHz center frequency and 150 kHz bandwidth align with system requirements. Consider the 7 dB insertion loss impact on signal strength. Verify that the 10-SMD no-lead package is compatible with assembly processes. Evaluate alternative active or passive filters if higher performance or modern compliance is required.

Part Context

This component belongs to Murata's portfolio of RF SAW filters. These devices are engineered for precise frequency control in wireless and broadcast equipment. The SF1194A represents a specific design point for narrowband filtering needs around the 167 MHz range, distinct from broadband or wideband filter families.

Replacement Considerations

Public data indicates the product status is obsolete. No direct public substitute part numbers are confirmed in the provided source material. Engineers should consult Murata's official obsolescence notices or search for equivalent SAW filters with matching 167 MHz specifications and 10-SMD packaging.
