ECS-DCF-109

Overview

The ECS-DCF-109 is a dielectric ceramic filter designed for surface mount applications. It operates within a temperature range of -40°C to +85°C and features a monoblock package with three PC pads. The component has a center frequency of 5.4425GHz and a bandwidth of 585 MHz, covering the 5150MHz to 5735MHz spectrum. Key electrical parameters include an insertion loss of 2.2dB, a rejection of 50dB, and a 50Ω input/output impedance. It withstands 50V DC voltage and maintains a minimum insulation resistance of 100MΩ.

Feature Summary

• Dielectric ceramic construction for stable RF performance
• Surface mount monoblock design with three pad configuration
• Optimized for specific microwave frequency bands

Applications

• Wireless LAN systems operating in the 5GHz band
• Microwave communication equipment
• RF signal filtering in high-frequency circuits

Procurement Notes

Verify the exact center frequency and bandwidth requirements against your circuit design before ordering. Confirm that the surface mount footprint dimensions match your PCB layout constraints. Ensure compatibility with standard reflow soldering profiles for monoblock ceramic components. Check for RoHS compliance if required by your manufacturing standards.

Selection Notes

Select this component when a fixed center frequency of 5.4425GHz is required for 5GHz wireless applications. Consider the 2.2dB insertion loss impact on system sensitivity. The monoblock package offers compactness but requires adequate spacing for thermal management during soldering. Verify impedance matching at 50Ω for optimal power transfer.

Part Context

ECS Inc. manufactures a range of ceramic filters for RF applications. The ECS-DCF-109 belongs to their dielectric ceramic filter series, which provides high Q-factor and stability. These components are typically used in conjunction with other passive elements to shape frequency responses in microwave circuits.

Replacement Considerations

Check for direct substitutes from ECS or other manufacturers offering identical 5.4425GHz center frequency and 585MHz bandwidth. Ensure replacement parts maintain the same 50Ω impedance and monoblock package dimensions. Verify that alternative components meet the same temperature and voltage specifications.
