RF1417D

Overview

The Murata Electronics RF1417D is a Surface Acoustic Wave (SAW) filter designed for signal conditioning applications. It operates at a center frequency of 315 MHz with a bandwidth of 600 kHz, covering a range from 314.85 MHz to 315.15 MHz. The component features a nominal impedance of 4.93 kOhms and supports a voltage rating of 12 V. It exhibits an insertion loss of 1.6 dB and utilizes SMD/SMT termination styles within the SM-3838-8 package. The device is qualified under AEC-Q200 standards and functions reliably within a temperature range of -40°C to +125°C.

Procurement Notes

Verify current product status as sources indicate this model may be obsolete or end-of-life. Confirm availability through authorized Murata distributors or alternative suppliers. Ensure compatibility with existing PCB layouts requiring the SM-3838-8 package. Check for updated replacement components if supply chain continuity is required for long-term production.

Selection Notes

Select this component when a 315 MHz SAW filter with high impedance matching is required. The 4.93 kOhms impedance differs from standard 50 Ohm systems, necessitating appropriate interface design. Consider the AEC-Q200 qualification for automotive deployments. Evaluate the 1.6 dB insertion loss against system sensitivity requirements. Verify package dimensions fit the target footprint constraints.

Part Context

The RF1417D belongs to Murata's specialized RF filter portfolio, targeting specific ISM band applications. It serves as a critical passive component in radio frequency front-end circuits. The device represents Murata's capability in producing high-performance SAW filters for niche frequency bands. Its design focuses on compact form factors suitable for modern electronic assemblies.

Replacement Considerations

Public documentation indicates the RF1417D is obsolete. Potential substitutes include other Murata 315 MHz SAW filters such as the RF1211D series, though impedance and package differences must be verified. Cross-reference technical specifications carefully before substitution.
