Overview
The Würth Elektronik 748032455 is a surface-mount ceramic common mode filter from the WE-CCMF series. It features a compact footprint of 1.25 x 1 x 0.8 mm and operates within a temperature range of -40 °C to +125 °C. The component provides a minimum common mode attenuation of 20 dB at frequencies of 2450 MHz and 5500 MHz. It has a DC current rating of 300 mA, an inductance of 0.245 nH, and a maximum DC resistance of 2.5 Ω.
Feature Summary
- Utilizes ceramic construction for high-frequency signal integrity
- Provides significant common mode noise attenuation in dual-band wireless applications
- Designed for direct surface-mount integration into compact circuit boards
Applications
- Wireless LAN modules requiring EMI suppression
- Bluetooth low energy (BLE) interface circuits
- Mobile device RF front-end filtering
Procurement Notes
Verify the specific datasheet version when sourcing, as manufacturer documentation may be updated. Confirm that the package dimensions and terminal configuration match the target PCB layout requirements. Ensure the operating temperature range aligns with the environmental conditions of the final assembly. Cross-reference the part number with official distributor catalogs to confirm availability and authenticity before procurement.
Selection Notes
Select this component when space constraints require a sub-millimeter height profile. Choose this filter for applications demanding high attenuation at 2.4 GHz and 5.5 GHz bands. Consider the 300 mA current rating to ensure it meets the power handling needs of the specific line. Evaluate the low inductance value to determine suitability for high-speed digital or RF signal paths where minimal insertion loss is critical.
Part Context
This component belongs to the WE-CCMF series, which focuses on small-footprint electromagnetic interference suppression. The series utilizes ceramic materials to achieve stable performance across wide frequency ranges. These filters are engineered for modern electronics where miniaturization and signal purity are primary design drivers.
Replacement Considerations
Consult official Wurth Elektronik documentation for verified substitute part numbers within the same series. Ensure any alternative maintains identical footprint dimensions and electrical characteristics.
