Overview
The Wurth Elektronik 7427001 is a solid ferrite bead core designed for effective broadband EMI suppression on round cables. Its primary function is to attenuate high-frequency noise by introducing impedance at critical frequencies, thereby improving signal integrity in sensitive electronic circuits. A key design consideration when selecting ferrite materials like the 4W1500 is the trade-off between impedance at higher frequencies and potential signal attenuation at lower frequencies; the 7427001 balances this by offering substantial impedance (38 Ohms) at 25 MHz and 100 MHz without unduly impacting fundamental signal bandwidth in many applications.
Key Features
- Core Material: 4W1500
- Impedance: 38 Ohms @ 25 MHz / 100 MHz
- Inside Diameter: 0.76 mm
- Outside Diameter: 2.5 mm
- Outside Length: 4 mm
- Operating Temperature Range: -25°C to +105°C
Applications
The component is engineered for deployment in systems requiring high reliability and performance under specific operating conditions. It provides functional stability across the stated design envelope.
- Suppression of conducted EMI on data lines in USB and HDMI interfaces.
- Filtering of switching noise in DC-DC converter outputs.
- Reducing common-mode noise on sensor signal wiring.
- Improving signal integrity in automotive infotainment systems.
