SIR315M500S042

Overview

The SIR315M500S042 is a Surface Acoustic Wave (SAW) resonator manufactured by NextGen Components, designed for surface mount applications. It operates at a nominal frequency of 315.5 MHz with a tolerance of +/-75 kHz and features a 50 Ohm impedance. The device utilizes a 4-pad 5035 package configuration, measuring 5.0 mm in length, 3.5 mm in width, and 1.5 mm in height. It exhibits a maximum insertion loss of 2.0 dB and functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• Utilizes Surface Acoustic Wave technology for stable frequency generation
• Designed for compact surface mount integration via 4-pad 5035 footprint
• Operates reliably across extended industrial temperature ranges

Applications

• RF signal filtering in communication modules
• Frequency reference components in wireless transceivers
• Oscillator circuits requiring precise 315.5 MHz stability

Procurement Notes

Verify the specific manufacturer designation and datasheet version prior to procurement. Confirm that the 5035 package dimensions and pinout align with the target PCB layout. Ensure thermal management strategies accommodate the specified -40°C to +85°C operational range for the intended application environment.

Selection Notes

Select this component when a 315.5 MHz SAW resonator with 50 Ohm impedance is required. Consider the 2.0 dB maximum insertion loss and +/-75 kHz tolerance against system requirements. Evaluate the 5035 SMD form factor for space-constrained designs needing robust performance across wide temperature variations.

Part Context

This part belongs to the SIR series of SAW resonators from NextGen Components. It shares the 5035 package style with other variants like the SIR315M000S041 but differs in nominal frequency and tolerance specifications. The series targets applications demanding reliable RF filtering in compact electronic assemblies.

Replacement Considerations

Direct substitutes include the SIR315M000S041, though it offers a tighter +/-50 kHz tolerance. Verify compatibility regarding insertion loss and exact frequency alignment before cross-referencing with other manufacturers' 315.5 MHz SAW devices.
