• Provides effective EMI/RFI suppression in the 2.45 GHz ISM band
• Compact 0603 footprint suitable for space-constrained mobile designs

Applications

• Wireless LAN modules
• Bluetooth devices
• Zigbee transceivers

Procurement Notes

Verify current availability as the DEA series has been subject to End-of-Life notifications. Confirm that the specific suffix matches required specifications, as variations exist within the family. Ensure compliance with RoHS3 requirements if mandated by project standards. Check for alternative components due to potential supply constraints associated with discontinued series.

Selection Notes

Select this component for applications requiring precise filtering in the 2.45 GHz range. The 100 MHz bandwidth accommodates standard modulation schemes for Bluetooth and Wi-Fi. Consider the 1.5 dB insertion loss when designing link budgets. The 0603 size allows for high-density PCB layouts. Verify thermal stability requirements against the specified -40°C to +85°C operating range.
