The component exhibits an impedance of 650 Ohms, an insertion loss of 2dB, and a ripple of 1dB. It supports a load capacitance of 5 pF and functions within a temperature range of -20°C to +70°C. The physical dimensions are 8 mm x 7.3 mm with a maximum height of 8.00 mm.

Feature Summary

• Monolithic construction for stable RF filtering performance
• Through-hole termination style for standard PCB integration
• Optimized for 45 MHz intermediate frequency applications

Applications

• Intermediate frequency (IF) stages in radio receivers
• Communication equipment requiring narrowband filtering
• Test and measurement instrumentation signal processing

Procurement Notes

Verify the specific datasheet revision from ECS Inc. to confirm mechanical tolerances and electrical characteristics match design requirements. Ensure the operating environment remains within the specified -20°C to +70°C range to maintain performance stability. Confirm that the 650 Ohm impedance aligns with the surrounding circuit topology before finalizing procurement.

Selection Notes

Select this component when a fixed 45 MHz center frequency with 15 kHz bandwidth is required. The 650 Ohm impedance dictates matching network design. Consider the through-hole package constraints for board layout. Verify that the 2dB insertion loss meets system sensitivity requirements compared to alternative filter technologies.

Part Context

This part belongs to the ECS Inc. monolithic crystal filter series, which provides compact solutions for RF signal conditioning. These filters utilize piezoelectric ceramic technology to achieve sharp roll-off characteristics. The series is commonly used in consumer electronics and industrial communication devices where size and cost efficiency are critical factors.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Cross-referencing requires identical electrical parameters including 45 MHz center frequency, 15 kHz bandwidth, and 650 Ohm impedance.
