SIR315M050S042

Overview

The SIR315M050S042 is a Surface Acoustic Wave (SAW) resonator manufactured by NextGen Components. It operates at a center frequency of 315.05 MHz with a frequency tolerance of ±75 kHz. The device features a 50 Ohm impedance and utilizes a 4-pad surface mount package, specifically the 5035 type (L5.0 x W3.5 x H1.5 mm). It is designed for operation within a temperature range of -40°C to +85°C.

Feature Summary

• Utilizes Surface Acoustic Wave technology for stable resonance
• Designed for surface mount integration via four contact pads
• Engineered for wide industrial temperature operational stability

Applications

• RF signal generation circuits
• Frequency reference sources in communication modules
• Filtering applications in wireless transceivers

Procurement Notes

Verify component authenticity through official manufacturer channels or authorized distributors. Confirm that the received part matches the specified 315.05 MHz frequency and 5035 package dimensions. Ensure storage conditions maintain integrity prior to assembly. Review the latest datasheet for any updates on handling sensitivity or soldering profiles specific to this SAW device.

Selection Notes

Select this component when a precise 315.05 MHz reference is required in space-constrained designs. The 5035 footprint offers a balance between performance and board area efficiency. Consider the ±75 kHz tolerance for system frequency planning. Evaluate thermal requirements against the -40°C to +85°C operating range to ensure reliability in the target environment.

Part Context

This SAW resonator belongs to the SIR series from NextGen Components, which specializes in RF passive components. The series includes various frequencies and packages, such as the SIR318M000S042. These devices are distinct from crystal oscillators, providing passive resonance without active drive circuitry, making them suitable for cost-sensitive RF front-end applications.

Replacement Considerations

Direct substitutes must match the 315.05 MHz frequency, 50 Ohm impedance, and 5035 package. Verify tolerance specifications and temperature ranges. Cross-reference with other manufacturers offering SAW resonators in QCC4A case codes. Ensure pin compatibility and mounting orientation align with existing PCB layouts.
