• Optimized for low insertion loss performance
• Compact surface-mount design suitable for space-constrained PCBs

Applications

• Wireless remote control systems
• Security alarm transmitters
• Industrial telemetry links

Procurement Notes

Verify the specific manufacturer designation when sourcing, as distribution channels may list this part under various distributor identifiers. Confirm the package dimensions and pad configuration match the target PCB footprint prior to integration. Ensure that the operating temperature range meets the environmental requirements of the final assembly. Cross-reference the frequency tolerance specifications against system design constraints to guarantee signal integrity.

Selection Notes

Select this component for applications requiring a fixed-frequency SAW resonator at 433.92 MHz. The choice depends on the need for a compact, low-loss solution compatible with standard surface-mount processes. Consider the ±100 kHz tolerance relative to receiver bandwidth capabilities. Evaluate the thermal stability within the specified -40°C to +85°C range against operational conditions.

Part Context

This part belongs to the SER series of SAW resonators offered by NextGen Components. These components are engineered for radio frequency applications where precise frequency generation is critical without the complexity of active oscillators. The series provides a passive alternative to crystal resonators, offering robust performance in consumer and industrial wireless devices.

Replacement Considerations

Direct substitutes must match the 433.92 MHz frequency, 50 Ohm impedance, and 1814 SMD package dimensions. Verify that any replacement maintains the ±100 kHz tolerance and similar insertion loss characteristics to ensure circuit compatibility.
