• Parallel fundamental resonance mode operation
• Compliance with RoHS3 environmental regulations

Crystals Applications

• Microcontroller clock source circuits
• General purpose timing applications
• Embedded system oscillator designs

Crystals Procurement Notes

Verify that the specific part number matches the required electrical parameters, particularly the 100 Ohm ESR and 5.0 MHz frequency. Confirm the package type is HC-49/US surface mount variant rather than through-hole. Ensure compliance requirements such as RoHS3 are met for the intended application environment. Cross-reference manufacturer datasheets for exact dimensional tolerances and storage conditions prior to procurement.

Crystals Selection Notes

Select this component when a standard HC-49/US footprint is required for surface mount assembly. The 100 Ohm ESR specification distinguishes it from lower resistance variants like the 50 Ohm models. Ensure the circuit design accommodates the 18 pF load capacitance requirement. Verify that the operating temperature range of -10°C to +60°C aligns with the system's thermal environment constraints.

Crystals Part Context

This part belongs to the CSM1 series of surface mount crystals from Cardinal Components Inc. The series offers various frequency and resistance options within the HC-49/US package. The suffix D18 indicates tape and reel packaging availability. This model represents a specific configuration within the broader family of fundamental mode quartz resonators designed for cost-effective mass production.
