Overview
The Murata Power Solutions 55100C is a surface-mount current sense transformer designed for high-frequency applications. It features a 1:1:100 turns ratio and an inductance of 14.8 mH. The component supports a rated current of 15 A with a secondary coil resistance of 850 mOhms. Operating within a frequency range of 50 kHz to 500 kHz, it utilizes SMD/SMT termination. Physical dimensions are 14.6 mm in length, 12.6 mm in width, and 7.1 mm in height.
Feature Summary
- Surface-mount construction for automated PCB assembly
- Integrated current sensing capability via 1:1:100 turns ratio
- Optimized for high-frequency operation between 50 kHz and 500 kHz
Applications
- High-frequency power supply current monitoring
- Switch-mode power supply (SMPS) feedback loops
- Isolated current sensing in DC-DC converters
Procurement Notes
Verify component status as the 55100C is listed as obsolete or discontinued by the manufacturer. Confirm availability through authorized distributors or surplus channels. Ensure that any sourced units match the original Murata Power Solutions specifications and RoHS compliance requirements before integration into production designs.
Selection Notes
Select this component when a surface-mount current transformer with a 15 A rating and 14.8 mH inductance is required. The 1:1:100 turns ratio provides appropriate signal scaling for control circuitry. Verify that the operating frequency falls within the 50 kHz to 500 kHz range and that the physical footprint fits the design constraints.
Part Context
The 55100C belongs to the current sense transformer category from Murata Power Solutions. It serves as a specialized passive component for electrical isolation and current measurement in power electronics. This part is distinct from general-purpose transformers due to its specific turns ratio and high-frequency characteristics tailored for sensing applications.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, alternative components must be evaluated based on matching electrical parameters such as inductance, turns ratio, and current rating.
