SAR403M550S032

Overview

The SAR403M550S032 is a surface-mount SAW resonator from NextGen Components, designed for high-frequency signal processing applications. It operates at a center frequency of 403.55 MHz with a tolerance of +/-75 kHz. The device features an insertion loss of 2.2 dB maximum and maintains a 50 Ohm impedance. Packaged in an 8-pad L5.0*W5.0*H1.5mm SMD form factor, it supports a temperature range of -40°C to 85°C.

Feature Summary

• Surface-mount SAW technology optimized for compact circuit integration
• High-frequency operation at 403.55 MHz with tight frequency stability
• Low insertion loss characteristics for efficient signal transmission

Applications

• RF front-end filtering in wireless communication modules
• Signal conditioning in industrial control systems
• Frequency selection in consumer electronics devices

Procurement Notes

Verify the specific ordering suffix against official NextGen Components documentation to ensure exact electrical parameters and packaging configuration match project requirements. Confirm that the 8-pad 5050 package dimensions align with PCB footprint specifications. Validate temperature range compliance for intended operating environments before finalizing procurement decisions.

Selection Notes

Select this component when a precise 403.55 MHz reference is required in space-constrained designs. The 50 Ohm impedance matches standard RF system architectures. Consider the +/-75 kHz tolerance for frequency-sensitive applications. Ensure thermal management strategies accommodate the -40°C to 85°C operational range during board layout planning.

Part Context

This part belongs to the SAR series of surface-mount SAW resonators manufactured by NextGen Components. The series includes various frequency options within similar physical packages. These components serve as passive frequency-determining elements in RF circuits, replacing bulkier through-hole alternatives while maintaining stable oscillation frequencies.

Replacement Considerations

Cross-reference compatible parts using identical center frequency (403.55 MHz), package type (8-SMD, 5050), and impedance (50 Ohms). Verify that substitute components meet or exceed the original insertion loss and tolerance specifications. Confirm thermal rating compatibility for direct replacement scenarios.
