What are the key specifications of the RS-03K105JT?

Key specs include 1MΩ resistance, ±5% tolerance, ±100ppm/℃ TCR, 100mW power rating at 70°C, and a maximum overload voltage of 50V.

What is the RS-03K105JT used for?

It is widely used in home appliances, computers, communications, industrial automation, and consumer electronics.

What should engineers review before using the RS-03K105JT?

Engineers should review the thermal management of the PCB, as the substrate is alumina and thermal expansion differences can cause solder joint cracks under repeated thermal cycling.

What are the sourcing risks for the RS-03K105JT?

As a standard passive component from a major manufacturer, supply risk is generally low, though availability should be confirmed via authorized distributors.

What is the pinout of RS-03K105JT?

Use the RS-03K105JT datasheet for the official pinout diagram and pin names. In PartGenie, ask Datasheet AI about RS-03K105JT pinout to locate pins, power rails, and interface signals before layout.
