SIR318M000S042

Overview

The SIR318M000S042 is a Surface Acoustic Wave (SAW) resonator manufactured by NextGen Components. It operates at a nominal frequency of 318 MHz with a frequency tolerance of ±75 kHz. The component features a 50 Ohm impedance and is designed for surface mount applications in the 4-SMD, no-lead package configuration, specifically size 5035. It has an operating temperature range of -40°C to +85°C and a maximum height of 1.50 mm.

Feature Summary

• Utilizes Surface Acoustic Wave technology for stable resonance
• Designed for high-frequency signal processing applications
• Supports surface mount assembly processes

Applications

• RF filter circuits
• Frequency reference sources
• Wireless communication modules

Procurement Notes

Verify the specific datasheet version from NextGen Components before integration. Confirm that the 4-SMD package dimensions align with your PCB footprint requirements. Ensure thermal management strategies accommodate the specified operating temperature range during final assembly.

Selection Notes

Select this component when a precise 318 MHz SAW resonator is required for compact RF designs. Consider the ±75 kHz tolerance and 50 Ohm impedance match against circuit specifications. Evaluate the surface mount form factor for automated placement compatibility.

Part Context

This part belongs to the SAW resonator category within NextGen Components' portfolio. It serves as a passive frequency-determining element, distinct from active oscillators or ceramic filters. The designation indicates specific acoustic wave properties tailored for mid-range RF frequencies.

Replacement Considerations

No public substitute part numbers are confirmed in available documentation. Cross-reference only if identical electrical parameters and package dimensions are verified through official manufacturer substitution lists.
