Product Description
Wurth Elektronik 742843122 WE-CBF HF 0402 unshielded multilayer surface mount inductor with a ferrite core is a compact and high-performance component engineered for suppression of high-frequency signals in intricate electronic circuits.
This inductor features a multilayer construction with a ferrite core material, ensuring low DC resistance of 380 milliohms and a maximum DC current capacity of 500mA. Its compact 0402 package (1mm length x 0.5mm height x 0.5mm depth) allows for efficient surface mounting in densely populated printed circuit boards.
The product is designed to operate reliably in harsh automotive environments, conforming to AEC-Q200 standards, and supporting a wide operating temperature range from -55°C to 125°C. The inductance tolerance is ±25%, suitable for applications requiring stable performance under varying conditions.
Key applications include high-speed data lines such as CPU interfaces, high-speed bus systems, and hard disk drives, where suppression of electromagnetic interference is critical. Compared with the standard WE-CBF series, this high-frequency version provides three times greater impedance at 1 GHz, enhancing EMI suppression efficiency.
Provided in tape and reel packaging, this inductor is ideal for automated surface mount technology assembly lines, improving manufacturing throughput and consistency. This multilayer inductor uses a ferrite core for effective high-frequency performance.
The 0402 package size enables compact PCB designs with minimal footprint. It supports a maximum DC current of 500mA with low DC resistance to minimize power loss. Compliance with AEC-Q200 automotive standard ensures reliability in critical applications.
Suitable for high-speed data line EMI suppression such as CPUs and hard drives. Operates over a wide temperature range from -55°C to 125°C. Manufactured in China and RoHS compliant. This component is widely used in electronics, automotive, communications, and computing industries for electromagnetic interference management in sensitive circuits.
