SAR303M825S031

Overview

The SAR303M825S031 is a Surface Mount Device (SMD) SAW resonator from the NextGen Components SAR series. It features an 8-pad QCC8C package with dimensions of 5.0mm length, 5.0mm width, and 1.5mm height. The component operates at a center frequency of 303.825 MHz with a frequency tolerance of ±50 kHz. It exhibits a maximum insertion loss of 1.8 dB and maintains a nominal impedance of 50 Ohms. The device is designed for surface mount applications and supports an operating temperature range of -40°C to +85°C.

Feature Summary

• Utilizes Surface Acoustic Wave (SAW) technology for stable resonance
• Compact 5050 type SMD footprint with eight connection pads
• Optimized for low insertion loss performance in RF circuits

Applications

• RF filter stages in wireless communication modules
• Frequency selection in mobile handset transceivers
• Signal processing in consumer electronic devices requiring precise frequency control

Procurement Notes

Verify that the specific part number matches the required frequency tolerance of ±50 kHz and the 303.825 MHz center frequency. Confirm the package type is the 8-pad QCC8C variant. Ensure the supplier provides documentation confirming the operating temperature range meets the -40°C to +85°C specification for your intended environment.

Selection Notes

Select this component when a compact SAW resonator is needed for 303.825 MHz applications. The 50 Ohm impedance matches standard RF transmission lines. Consider the 8-pad configuration for improved thermal dissipation and mechanical stability compared to smaller packages. Verify compatibility with reflow soldering profiles suitable for the specified temperature range.

Part Context

This part belongs to the SAR series of SMD SAW resonators manufactured by NextGen Components. The series offers various frequencies and tolerances within a standardized 5050 case size. The SAR303M825S031 specifically targets the 303 MHz band with tight frequency stability requirements.

Replacement Considerations

The SAR303M825S032 is a documented substitute offering a wider frequency tolerance of ±75 kHz at the same 303.825 MHz center frequency. Verify if the relaxed tolerance meets system requirements before substitution.
