NFA21SL337V1A45L

Overview

The NFA21SL337V1A45L is an EMI Network Filter Array manufactured by Murata Electronics. It features a second-order low-pass LC filter configuration with four independent channels integrated into a single package. The component has a cutoff frequency of 330 MHz and supports a maximum current of 100 mA. It utilizes a surface-mount device (SMD) termination style within a compact 0805 (2012 metric) footprint, measuring 2.0x1.25mm. This design provides steep insertion loss characteristics suitable for noise suppression in frequencies of 800 MHz or higher.

Feature Summary

• Integrates four independent LC filter circuits within a single compact package to save board space.
• Provides steep insertion loss characteristics for effective noise suppression in high-frequency applications.
• Designed specifically for suppressing electromagnetic interference at frequencies of 800 MHz or higher.

Applications

• Noise suppression in wireless communication systems
• EMI filtering for high-speed digital signal lines
• Signal integrity protection in mobile devices

Procurement Notes

Verify the lifecycle status before procurement as this component is marked as Not Recommended for New Designs (NRND). Confirm that the 0805 package dimensions and 100 mA current rating align with your specific circuit requirements. Ensure compatibility with existing PCB footprints and soldering processes for SMD components.

Selection Notes

Select this component when a multi-channel EMI solution is required in a minimal footprint. The 330 MHz cutoff frequency makes it suitable for applications requiring attenuation above this threshold. Consider the NRND status if designing new products; verify availability for production runs if replacing existing designs.

Part Context

This part belongs to Murata's EMI Filter Circuits category, specifically designed as an EMI Network Filter Array. It is part of a series offering compact solutions for noise suppression. The 0805 package size allows for dense PCB layouts, making it common in portable electronics where space is constrained.

Replacement Considerations

As the component is Not Recommended for New Designs (NRND), evaluate alternative Murata EMI filter arrays with similar cutoff frequencies and package sizes. Verify pinout compatibility and electrical specifications such as current rating and insertion loss curves before substituting.
