DLM0QSN500HY2D

Common Mode Chokes Overview

The DLM0QSN500HY2D is a single-channel common mode filter choke manufactured by Murata Electronics. It features an impedance of 50 Ohms at 100 MHz with a tolerance of 35%. The component supports a maximum DC current of 100 mA and has a maximum DC resistance of 4.5 Ohms. Designed for surface mount installation, it operates within a temperature range of -40°C to +85°C. The physical dimensions are 0.65 mm in length, 0.5 mm in width, and 0.3 mm in height, corresponding to the 025020 (0605 metric) package.

Common Mode Chokes Feature Summary

• Provides common mode noise suppression for high-speed signal lines
• Ultra-low profile design suitable for space-constrained PCB layouts
• Single-channel configuration for differential pair filtering

Common Mode Chokes Applications

• High-speed data interface noise filtering
• Portable electronic device signal integrity protection
• Consumer electronics circuit board EMI suppression

Common Mode Chokes Procurement Notes

Verify the specific suffix HY2D against official Murata documentation to confirm packaging type and tape/reel specifications. Ensure the procurement channel sources genuine components from authorized distributors to guarantee compliance with RoHS standards and prevent counterfeit parts. Cross-reference the Mouser part number 81-DLM0QSN500HY2D for accurate availability tracking.

Common Mode Chokes Selection Notes

Select this component when a 50 Ohm impedance at 100 MHz is required for common mode noise reduction. The 100 mA current rating dictates suitability for low-power signal lines rather than power delivery paths. The 0605 metric footprint allows for compact board designs where larger chokes cannot fit. Verify that the 4.5 Ohm DC resistance does not exceed the voltage drop limits of the target circuit.

Common Mode Chokes Part Context

This component belongs to the DLM0QSN series of EMIFIL common mode chokes. It serves as a successor or alternative to older NFP0QSN series products, such as the discontinued NFP0QSN122HL2D. The series focuses on miniaturization while maintaining effective noise filtering capabilities for modern high-density electronic assemblies.

Common Mode Chokes Replacement Considerations

The NFP0QSN122HL2D is officially listed as a discontinued product with DLM0QSN500HY2D identified as a similar substitute. Verify electrical parameter compatibility before swapping, as impedance values may differ between the two models.
