ECS-38SMF45A15

Overview

The ECS-38SMF45A15 is a monolithic crystal filter manufactured by ECS Inc. It operates at a center frequency of 45 MHz with a bandwidth of 15 kHz. The component features an impedance of 560 Ohms and provides 2 dB insertion loss. It is housed in an 8-SMD, no lead surface mount package measuring 3.80mm x 3.80mm with a maximum height of 1.1938mm.

Feature Summary

• Monolithic crystal construction for stable signal filtering
• Surface mount design for automated assembly
• High selectivity with narrow bandwidth

Applications

• Intermediate frequency (IF) stages in communication receivers
• Signal conditioning in RF circuits
• Frequency selection in wireless devices

Procurement Notes

Verify the exact part number against official ECS Inc. documentation to ensure compatibility. Confirm that the 45 MHz center frequency and 15 kHz bandwidth match your circuit requirements. Check RoHS compliance status if environmental regulations apply. Ensure the 8-SMD package dimensions fit your PCB layout constraints before ordering.

Selection Notes

Select this component when a fixed 45 MHz center frequency is required. The 560 Ohm impedance must match the source and load impedances in the design. Consider the 2 dB insertion loss impact on signal strength. The surface mount package requires appropriate soldering profiles for reliable attachment.

Part Context

This component belongs to the ECS Inc. monolithic crystal filter series. These filters are designed for high-performance applications requiring precise frequency selection. The 38SMF series offers compact packaging suitable for modern electronic devices. They provide better stability compared to traditional LC filters.

Replacement Considerations

No public substitute part numbers are confirmed in the provided data. Verify compatibility with any alternative components by matching the 45 MHz frequency, 15 kHz bandwidth, and 560 Ohm impedance specifications.
