DLP11RB400UL2L

Common Mode Chokes Overview

The Murata DLP11RB400UL2L is a surface-mount common mode choke designed for signal line applications. It features a compact footprint with dimensions of 1.25 mm length, 1.0 mm width, and a low profile height of 0.5 mm ±0.1 mm. The component provides an impedance of 40 Ohms at 100 MHz and supports a maximum DC current rating of 100 mA. Its maximum DC resistance is specified as 1.63 Ohms. The device operates within a temperature range of -40°C to +85°C and utilizes a film construction type.

Common Mode Chokes Feature Summary

• Compact physical footprint with ultra-low profile design suitable for space-constrained PCB layouts
• High cutoff frequency characteristic ensuring effective noise suppression in high-speed signal lines
• High coupling efficiency inherent to the two-line common mode choke architecture

Common Mode Chokes Applications

• Signal line noise filtering in electronic circuits
• EMI suppression in portable consumer devices
• Common mode interference reduction in data transmission interfaces

Common Mode Chokes Procurement Notes

Verify component status carefully as sources indicate this part may be obsolete or last-time buy. Confirm availability through authorized distributors rather than general stock claims. Ensure the ordering suffix matches the required package configuration. Cross-reference datasheets for updated RoHS and REACH compliance details before finalizing procurement plans.

Common Mode Chokes Selection Notes

Select this component when a low-profile solution is required for signal integrity protection. The 40 Ohm impedance at 100 MHz suits moderate frequency noise attenuation needs. Consider the 100 mA current limit for circuit compatibility. The 1.25x1.0 mm SMD package fits standard footprints but requires verification against existing board designs.

Common Mode Chokes Part Context

This component belongs to the Murata DLP11R series of common mode chokes. It is engineered for surface-mount technology integration. The series emphasizes miniaturization while maintaining electrical performance for signal line protection. It serves as a passive filter element within broader electromagnetic interference mitigation strategies.

Common Mode Chokes Replacement Considerations

Murata suggests the DLM0NSN500HY2D as an alternate part. Verify electrical compatibility and physical dimensions before substitution. Check if the alternative meets specific impedance and current requirements.
