ADFC18-2450.00-A-T

Overview

The Abracon ADFC18-2450.00-A-T is a surface-mount dielectric bandpass filter designed for the 2.45 GHz ISM band. It features a center frequency of 2450 MHz with a bandwidth of 100 MHz. The component operates at a standard impedance of 50 Ohms and exhibits an insertion loss ranging from 1.4 dB to 1.8 dB depending on specific testing conditions. It supports a maximum operating temperature of +85°C and is available in both cut tape and tape & reel packaging formats within a compact 0603 (1608 Metric) package.

Feature Summary

• Compact low-profile SMD design enabling high-density mounting
• Low insertion loss and high attenuation characteristics
• Dielectric construction for stable RF performance

Applications

• Wireless LAN modules
• Bluetooth devices
• ISM band applications

Procurement Notes

Verify the specific suffix 'A-T' confirms tape and reel packaging if reel quantity is required. Confirm the exact insertion loss specification against the latest official datasheet, as values may vary slightly between 1.4 dB and 1.8 dB based on test setups. Ensure the 0603 footprint matches the PCB layout requirements.

Selection Notes

Select this component for applications requiring a narrow 100 MHz bandwidth at 2.45 GHz. The 50 Ohm impedance is standard for most RF systems. Consider the thermal limit of +85°C when designing for high-temperature environments. The small form factor is suitable for space-constrained portable electronics.

Part Context

This part belongs to Abracon's ADFC18 series of dielectric bandpass filters. These components are engineered for RF filtering in wireless communication systems. The series offers various center frequencies tailored to different global standards, with this specific model targeting the widely used 2.45 GHz industrial, scientific, and medical band.

Replacement Considerations

Check for other Abracon models in the ADFC18 series with compatible center frequencies. Verify that any substitute maintains the same 0603 footprint and 50 Ohm impedance. Ensure the replacement meets the required bandwidth and insertion loss specifications for the specific application.
