SIR868M950S043

Overview

The SIR868M950S043 is a Surface Acoustic Wave (SAW) resonator manufactured by NextGen Components. It operates at a center frequency of 868.95 MHz with a tolerance of +/-100 kHz. The device features a 50 Ohm impedance and is housed in a 4-SMD, No Lead surface mount package. It supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Utilizes Surface Acoustic Wave technology for stable frequency generation
• Designed for surface mount assembly via a leaded SMD package
• Engineered for operation within industrial temperature ranges

Applications

• RF signal filtering in communication systems
• Frequency reference components in wireless transceivers
• Signal processing stages in IoT devices

Procurement Notes

Verify the specific manufacturer part number against official NextGen Components documentation to ensure authenticity. Confirm that the 4-SMD package dimensions match your PCB footprint requirements. Check that the 868.95 MHz frequency aligns with regional regulatory standards for your target application. Ensure soldering profiles are compatible with the specified temperature ratings.

Selection Notes

Select this component when a precise 868.95 MHz SAW resonator is required for surface mount designs. Consider the 50 Ohm impedance for matching network compatibility. Evaluate the +/-100 kHz tolerance against system phase noise requirements. Verify that the -40°C to +85°C range covers the environmental conditions of the end product.

Part Context

This component belongs to the SAW resonator category within NextGen Components' portfolio. It serves as a passive frequency control element, distinct from active oscillators or crystals. The 4-SMD form factor allows for automated placement in high-volume manufacturing processes.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Cross-referencing requires identical frequency, tolerance, impedance, and package specifications.
