Common Mode Chokes datasheet and documents for DLP31SN551ML2L
Common Mode Chokes Overview
The DLP31SN551ML2L is a two-line common mode choke coil from the Murata DLP31S series, designed for surface mount applications. It features an impedance of 550 Ohms at 100 MHz and supports a maximum DC current of 100 mA. The component has a maximum DC resistance of 3.6 Ohms and operates within a temperature range of -40°C to +85°C. Housed in a 1206 (3216 metric) package with dimensions of 3.2 mm x 1.6 mm x 1.30 mm, it provides EMI suppression for signal lines.
Common Mode Chokes Feature Summary
- Provides effective electromagnetic interference suppression for dual-channel signal lines through high impedance characteristics at 100 MHz.
- Utilizes a compact film-type structure suitable for space-constrained printed circuit board layouts.
- Maintains stable performance across industrial temperature ranges from -40°C to +85°C.
Common Mode Chokes Applications
- EMI filtering for high-speed data communication interfaces
- Signal line protection in portable electronic devices
- Noise suppression in automotive infotainment systems
Common Mode Chokes Procurement Notes
Verify component authenticity against official Murata documentation due to end-of-life status. Confirm lot codes and RoHS compliance certificates match current regulatory requirements. Check for authorized distributor channels to avoid counterfeit sources. Validate packaging integrity for surface mount handling. Ensure design-in approval accounts for discontinued availability timelines.
Common Mode Chokes Selection Notes
Select this component when specific 550 Ohm impedance at 100 MHz is required for dual-line noise reduction. Consider the 100 mA current rating limits for power distribution applications. Evaluate the 1206 footprint compatibility with existing PCB silkscreens. Compare thermal dissipation capabilities against similar series alternatives if higher current capacity is needed.
