The component features an 8 pF load capacitance and a maximum equivalent series resistance (ESR) of 50 Ohms. It utilizes a 4-SMD, no lead package configuration. The device is designed for surface mount applications and supports a standard operating temperature range of -20°C to +70°C.

Feature Summary

• Surface mount design with a 4-SMD, no lead package profile
• Parallel fundamental quartz crystal operation mode
• Hermetically sealed construction ensuring moisture sensitivity level N/A
• Compliant with RoHS standards for reflow soldering processes

Applications

• Wireless communication modules requiring precise timing references
• IoT connectivity devices utilizing WiFi, Bluetooth, or BLE protocols
• Telecommunication equipment including cellular modem interfaces

Procurement Notes

Verify the specific suffix 'AAV-T' against official QST documentation to confirm tape and reel packaging specifications. Ensure the load capacitance requirement of the host circuit matches the 8 pF specification. Confirm that the operating temperature range of -20°C to +70°C aligns with the environmental conditions of the target application. Cross-reference the ESR limit of 50 Ohms with oscillator driver strength capabilities.

Selection Notes

Select this component when a 49.152 MHz reference signal is required for wireless or telecommunication circuits. The choice depends on the compatibility of the 8 pF load capacitance with the system's oscillator circuitry. Consider the ±30 ppm stability requirement against the overall system timing budget. Verify that the surface mount form factor fits within the mechanical constraints of the printed circuit board layout.

Part Context
