Overview
The Murata Power Solutions 51105C is a through-hole common mode choke filter designed for power line applications. It features an inductance of 1 mH with a tolerance range of -30% to +50%. The component supports a maximum DC current rating of 3.3 A and has a maximum DC resistance of 0.038 ohms. Its physical dimensions are 18 mm in length, 10 mm in width, and 24 mm in height. The device operates within a temperature range of -40°C to +125°C.
Feature Summary
- Provides common mode noise filtering for power lines
- Utilizes a toroidal core structure for efficient magnetic performance
- Designed for through-hole PCB mounting
Applications
- Power supply input filtering
- DC-DC converter noise suppression
- General electronic equipment EMI reduction
Procurement Notes
Verify the specific datasheet version and RoHS compliance status prior to procurement. Confirm that the 3.3 A current rating aligns with your circuit requirements. Ensure the through-hole package dimensions fit your PCB layout constraints. Check for any recent discontinuance notifications or lifecycle changes from the manufacturer.
Selection Notes
Select this component when a 1 mH inductance value is required for common mode noise attenuation in power circuits. The high current rating of 3.3 A makes it suitable for applications with significant DC load currents. Consider the operating temperature range up to 125°C for environments with elevated thermal conditions. Compare against other series if lower profile or different mounting styles are needed.
Part Context
This component belongs to the Murata Power Solutions common mode choke family. It is distinct from surface mount variants like the 50105C and radial leaded inductors such as the 15105C. The 51105C specifically targets through-hole assembly processes and higher current handling capabilities compared to smaller SMD options.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Users should consult official Murata Power Solutions resources for equivalent recommendations based on specific electrical and mechanical constraints.
