NFA18SL187V1A45L

Overview

The Murata NFA18SL187V1A45L is an active EMI network filter array designed for surface mount applications. It features a 0603 (1608 Metric) package with dimensions of 1.6 mm length, 0.8 mm width, and 0.5 mm height. The component operates within a rated voltage of 10V DC and an operating temperature range of -40°C to 85°C. It functions as a second-order low-pass LC filter with four channels, supporting a maximum current of 50 mA. The cutoff frequency is specified at 180 MHz, providing attenuation characteristics suitable for high-frequency noise suppression.

Feature Summary

• Integrates four independent filtering channels within a compact surface-mount footprint
• Utilizes LC circuit topology for effective electromagnetic interference suppression
• Designed for low-profile installation in space-constrained electronic assemblies

Applications

• High-speed data line protection in portable communication devices
• Signal integrity management in mobile phone motherboards
• Noise filtering for USB or HDMI interface circuits

Procurement Notes

Verify the specific suffix V1A45L against the manufacturer's latest datasheet to confirm pinout and termination compatibility. Ensure the selected variant matches the required 180 MHz cutoff frequency for the target application spectrum. Cross-reference the 10V rating and 50 mA current limit with system power requirements to prevent operational failure under load conditions.

Selection Notes

Select this component when a multi-channel solution is required to minimize board space compared to discrete filters. The 0603 array format offers a balance between filtering performance and physical size. Consider the -40°C to 85°C temperature range to ensure reliability in standard commercial environments. Evaluate the 180 MHz cutoff against the signal bandwidth to avoid unwanted signal attenuation.

Part Context

This part belongs to Murata's NFA series of EMI/RFI filter arrays. These components are engineered to replace multiple discrete inductors and capacitors, simplifying circuit design. The series is widely used in consumer electronics where space efficiency and signal cleanliness are critical priorities for modern device miniaturization.

Replacement Considerations
