Overview
The SAR433M420S032 is a Surface Mount Device (SMD) SAW resonator from the SAR series, manufactured by NextGen Components. It features an 8-pad configuration housed in a 5050 type package with dimensions of L5.0mm x W5.0mm x H1.5mm. The component operates at a center frequency of 433.420MHz with a tolerance of +/-75KHz. It exhibits a maximum insertion loss of 2.0 dB and supports an operating temperature range of -40°C to +85°C.
Feature Summary
- Utilizes Surface Acoustic Wave (SAW) technology for stable frequency generation
- Designed for surface mount assembly with an 8-pad configuration
- Compact 5050 type package structure suitable for space-constrained layouts
Applications
- Wireless communication modules requiring 433 MHz band operation
- Remote keyless entry systems
- Industrial remote control applications
Procurement Notes
Verify that the ordered part number matches SAR433M420S032 exactly, ensuring the 8-pad variant rather than other pin counts. Confirm the center frequency specification aligns with system requirements of 433.420MHz. Check packaging details to ensure compatibility with automated placement equipment if applicable. Validate manufacturer origin as NextGen Components to avoid counterfeit components.
Selection Notes
Select this component when a precise 433.420MHz reference is required for wireless transmission or reception circuits. The 8-pad design offers specific grounding and connection characteristics distinct from 4-pin variants. Ensure the PCB footprint accommodates the 5.0mm x 5.0mm outline. Consider the thermal operating range of -40°C to +85°C for environmental suitability.
Part Context
This resonator belongs to the SAR series of SMD SAW devices, characterized by standardized 5050 type dimensions. It serves as a frequency-determining element in RF circuits, replacing bulkier crystal oscillators. The 8-pad architecture distinguishes it from lower-pin-count alternatives within the same frequency family.
Replacement Considerations
Direct substitutes include SAR433M920S032 for different frequencies within the same package. Cross-reference SIR433M420S042 only if 4-pin compatibility is acceptable, noting the structural difference.
