SBR303M825S021

Overview

The SBR303M825S021 is a Surface Acoustic Wave (SAW) resonator manufactured by NextGen Components. It operates at a center frequency of 303.825 MHz with a frequency tolerance of ±50 kHz and an impedance of 50 Ohms. The component utilizes a 6-SMD, No Lead package configuration, specifically the 3838 Type case code DCC6, with physical dimensions of 3.8 mm in length, 3.8 mm in width, and 1.5 mm in height. It is designed for surface mount applications and functions within an operating temperature range of -40°C to 85°C.

Feature Summary

• Utilizes Surface Acoustic Wave technology for stable resonance generation
• Designed for direct surface mount integration via six-pad no-lead configuration
• Engineered for operation across extended industrial temperature ranges

Applications

• RF signal processing circuits requiring precise frequency reference
• Wireless communication modules operating near 300 MHz bands
• Industrial control systems utilizing SAW-based filtering or timing

Procurement Notes

Verify that the specific order matches the SBR Series designation and the 3838 Type case code DCC6 to ensure correct physical footprint compatibility. Confirm the frequency tolerance requirement aligns with the ±50 kHz specification provided in the official documentation. Ensure the procurement channel sources genuine components from authorized distributors to maintain reliability standards for the specified temperature range.

Selection Notes

Select this component when a fixed-frequency SAW resonator is required for 303.825 MHz applications with strict dimensional constraints due to its compact 3.8x3.8 mm footprint. Consider the 50 Ohm impedance match for system interface compatibility. Evaluate the ±50 kHz tolerance against system phase noise requirements. This part is suitable where low profile and surface mount assembly are prioritized over tunable frequency options.

Part Context

This device belongs to the SBR Series of SMD SAW resonators produced by NextGen Components. It is categorized under general line electronic components, specifically within the resonators and filters segment. The series is characterized by standardized surface mount packages designed for automated assembly processes in consumer and industrial electronics manufacturing.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Cross-referencing requires matching the 303.825 MHz frequency, 50 Ohm impedance, and 6-SMD package dimensions.
