Common Mode Chokes datasheet and documents for DLW44SM251SK2L
Common Mode Chokes Overview
The DLW44SM251SK2L is a wirewound common mode choke from the Murata EMIFIL series, designed for surface mount PCB assembly. It features a single-channel configuration with an impedance of 250 Ohms at 100 MHz and a maximum DC resistance of 33.6 mOhms. The component supports a maximum DC current of 2.6 A and operates within a temperature range of -40°C to +105°C. Housed in a compact 2012 (0804 metric) package measuring 2.0 mm x 1.25 mm x 1.25 mm, it provides effective electromagnetic interference suppression without shielding.
Common Mode Chokes Feature Summary
- Provides common mode noise attenuation through wirewound construction
- Designed for high-density surface mount integration
- Operates reliably across extended industrial temperature ranges
Common Mode Chokes Applications
- High-speed data line noise suppression
- USB interface circuit protection
- HDMI signal integrity enhancement
- General purpose EMI filtering in portable electronics
Common Mode Chokes Procurement Notes
Verify the specific suffix SK2L against official Murata documentation to confirm package dimensions and termination specifications. Ensure compatibility with standard reflow soldering profiles for 2012 case sizes. Cross-reference the impedance value at 100 MHz with system requirements. Confirm RoHS compliance status via the manufacturer's latest datasheet before finalizing procurement orders.
Common Mode Chokes Selection Notes
Select this component when space constraints require a 2012 footprint for common mode filtering. The 2.6 A current rating suits moderate power applications, while the 250 Ohm impedance targets higher frequency noise. Compare against shielded alternatives if magnetic field containment is critical. Validate thermal performance under continuous load conditions within the specified operating temperature limits.
Common Mode Chokes Part Context
This part belongs to the DLW44 series of unshielded chip common mode chokes. It utilizes Murata's proprietary wirewound technology to achieve stable inductance characteristics. The EMIFIL branding indicates its classification within the company's electromagnetic interference suppression portfolio, targeting consumer and industrial electronic devices requiring compact noise mitigation solutions.
Common Mode Chokes Replacement Considerations
Consult official Murata substitution guides for verified equivalents. Generic cross-references may not match the precise 2012 footprint or 250 Ohm impedance tolerance. Verify that any substitute maintains the same 2.6 A current handling capability and operates within the -40°C to +105°C range.
