The RJ4D03-10K appears to be a resistor, likely with a resistance value of 10K Ohms. Given the naming convention, RJ4D03 indicates the series, and 10K denotes 10,000 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 house.

Applications

• Voltage dividers
• Pull-up/pull-down resistors
• Current limiting resistors
• Feedback resistors in amplifiers

Features

• Fixed resistance value
• Axial leaded package (likely)
• Carbon film or metal film construction (depending on the manufacturer)

Benefits

• Simple to use in circuits
• Cost-effective resistance solution
• Standard resistance value

Technical Details (Assumptions):

Without a datasheet, it is difficult to provide exact specifications. Typical axial resistors of this size would have a power rating of 0.25W or 0.5W. Tolerance would also be a factor, likely being 5% or 10%.
