Overview
The Wurth Elektronik 74279252 is a high-performance EMI suppression ferrite bead designed for critical signal integrity applications. Its primary function is to attenuate unwanted high-frequency noise by presenting a high impedance at specific frequencies, crucial for preventing signal degradation in sensitive circuits. A key design consideration is the trade-off between impedance magnitude and DC current handling; while this WE-CBF series component offers a substantial 940 Ohms impedance, engineers must carefully select the operating frequency range to avoid excessive voltage drop under high load conditions, ensuring optimal noise filtering without compromising power delivery.
Key Features
- Impedance: 940 Ohms @ 100 MHz
- Maximum DC Current: 4 A
- Maximum DC Resistance: 35 mOhms
- Operating Temperature Range: -25 °C to +125 °C
- SMD/SMT Termination Style
- Dimensions: 4.5 mm (L) x 3.2 mm (W) x 1.5 mm (H)
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.
- Power line filtering for automotive ECUs
- Suppression of common-mode noise in USB 3.0 interfaces
- EMI reduction in high-speed digital signal paths
- Filtering of switching noise in DC-DC converters
