The RJ4D03-100R appears to be a power inductor or a wirewound resistor, likely with a resistance value of 100 Ohms. Given the naming convention, RJ4D03 indicates the series, and 100R denotes 100 ohms resistance. Although the manufacturer is listed as 'Others', it likely signifies that it is produced by a less well-known manufacturer or a custom winding house.

Applications

• Power supplies
• DC-DC converters
• Filtering circuits
• Current limiting circuits

Features

• Wirewound construction
• Fixed resistance/inductance value
• Relatively high current handling capability (depending on size)
• Axial leaded package (likely)

Benefits

• Simple to use in circuits
• Cost-effective current limiting or filtering solution
• Reliable operation in power applications (if properly rated)

Technical Details (Assumptions):

Without a datasheet, it is difficult to provide exact specifications. Typical axial resistors or inductors of this size would have power ratings between 0.25W to 1W (for resistors) or saturation current ratings of a few amps (for inductors). Tolerance would also be a factor, likely being 5% or 10%.
