Procurement Notes

Verify the exact package dimensions and lead configuration against the mechanical drawings in the official datasheet before integration. Confirm that the operating temperature range meets the environmental requirements of the final assembly. Ensure compatibility with the circuit's load capacitance specifications to maintain the specified center frequency accuracy. Cross-reference the manufacturer part number with authorized distributors to guarantee authenticity and traceability.

Selection Notes

Select this component when a fixed 45 MHz center frequency with a 15 kHz bandwidth is required. Consider the 1.2 kOhm impedance and 1.5 pF load capacitance for proper circuit matching. Evaluate the thermal performance within the -20°C to +70°C range against the application environment. Compare the physical footprint of the UM-1 package against available board space constraints.

Part Context

This component belongs to the family of monolithic crystal filters produced by ECS Inc. These devices are engineered for high stability and selectivity in signal conditioning roles. The series typically offers various center frequencies and bandwidth options to suit different communication and timing standards.
