DLP11RN450UL2L

Common Mode Chokes Overview

The Murata DLP11RN450UL2L is a surface-mount common mode choke coil from the DLP11R series, designed for high-density PCB applications. It features a compact 0504 (1210 metric) package with dimensions of 1.25 mm length, 1 mm width, and 0.82 mm height. The component provides an impedance of 45 Ohms at 100 MHz with a tolerance of 20%. It supports a maximum DC current rating of 100 mA and has a maximum DC resistance of 1 Ohm. The device operates within a temperature range of -40°C to +85°C.

Common Mode Chokes Feature Summary

• Film type construction for stable electromagnetic interference suppression
• Ultra-low profile design suitable for space-constrained mobile devices
• Dual-line configuration for effective common mode noise reduction

Common Mode Chokes Applications

• Portable electronic devices requiring EMI suppression
• Mobile communication interfaces
• High-speed data lines in compact consumer electronics

Common Mode Chokes Procurement Notes

Verify the specific suffix 'UL2L' against official Murata documentation to confirm packaging details and compliance status. Confirm that the component is currently available as active stock rather than obsolete or restricted items. Ensure compatibility with automated pick-and-place equipment due to the small 0504 footprint. Check for RoHS compliance declarations in the latest datasheet before integration into regulated products.

Common Mode Chokes Selection Notes

Select this component when a low-profile solution is required for dual-line signal integrity protection. The 45 Ohm impedance value targets specific frequency ranges for common mode noise attenuation. Consider the 100 mA current rating to ensure it meets the operational requirements of the target circuit without saturation. The film type construction offers reliability advantages over wire-wound alternatives in thin form factors.

Common Mode Chokes Part Context

This part belongs to the Murata EMIFIL DLP11 series, which specializes in ultra-small common mode chokes. The series is engineered for modern portable electronics where board space is limited. The DLP11R variant specifically denotes the resistance characteristics and packaging style within the broader DLP11 family of components.

Common Mode Chokes Replacement Considerations

Murata suggests the DLM0NSN500HY2D as an alternate option. Verify if the alternative matches the required impedance and current ratings for the specific application.
