DLP31SN121SL2L

Common Mode Chokes Overview

The DLP31SN121SL2L is a two-line common mode choke coil from the Murata DLP31 series, designed for surface mount applications. It features an impedance of 120 Ohms at 100 MHz and supports a maximum DC current of 100 mA. The component has a maximum DC resistance of 2 Ohms and operates within a temperature range of -40°C to +85°C. Housed in a 1206 (3216 metric) package with four terminals, it measures 3.2 mm in length, 1.6 mm in width, and up to 1.30 mm in height.

Common Mode Chokes Feature Summary

• Provides common mode noise suppression for signal lines through dual-channel filtering.
• Utilizes a compact 1206 surface mount footprint for efficient PCB integration.
• Constructed as a film type coil suitable for data line protection.

Common Mode Chokes Applications

• Signal line EMI suppression
• Data line filtering
• Common mode noise reduction in electronic circuits

Common Mode Chokes Procurement Notes

Verify component status carefully as this part is listed as obsolete or end-of-life by the manufacturer. Confirm availability through authorized distributors or secondary markets. Ensure that any sourced units meet original RoHS compliance standards. Check datasheet revisions for any specific handling or storage requirements associated with legacy inventory.

Common Mode Chokes Selection Notes

Select this component when a 1206 package size is required for common mode filtering with a 120 Ohm impedance at 100 MHz. It is appropriate for low-current signal lines requiring 100 mA rating. Consider alternative active parts if long-term supply stability is critical, as this model faces discontinuation risks.

Common Mode Chokes Part Context

This component belongs to the DLP31 series of common mode chokes manufactured by Murata Electronics. The series offers various impedance and current ratings in standard SMD packages. The DLP31SN121SL2L specifically targets applications needing moderate noise suppression in space-constrained designs using the widely adopted 1206 form factor.

Common Mode Chokes Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, direct replacements may require evaluating similar DLP series variants or consulting Murata for current equivalent recommendations.
