The RK73H1JTTD1541F is a precision thick film flat chip resistor from KOA Speer Electronics’ RK73H series, designed for applications requiring tight tolerance and low temperature coefficient. The resistor utilizes a metal glaze thick film deposited on a high-purity alumina ceramic substrate, providing excellent heat resistance and environmental stability. The triple-layer electrode construction consists of an inner electrode (Ag/Pd thick film), nickel plating for barrier protection, and tin plating for solderability. With ±1% tolerance and ±100 ppm/°C TCR, this device is well-suited for precision voltage dividers, feedback networks, and signal conditioning circuits. AEC-Q200 qualification ensures the component meets stringent automotive reliability standards, including resistance to thermal shock, moisture, and extended high-temperature exposure.

The RK73H1JTTD1541F operates as a passive thick film resistor:

1. Resistive Element: A metal glaze thick film (ruthenium oxide based) is screen-printed onto the alumina ceramic substrate and fired at high temperature. The resistance value is determined by the film composition, thickness, and geometric pattern.

2. Triple-Layer Electrode: The inner electrode (Ag/Pd alloy) provides low-resistance contact to the resistive film. The nickel barrier layer prevents solder leaching and migration. The outer tin plating enables reliable solder joint formation during assembly.

3. Power Derating: At ambient temperatures up to 70°C, the full 0.1W power rating is available. Above 70°C, the allowable power dissipation decreases linearly to zero at 155°C.

4. Voltage Limitation: The effective working voltage is the lesser of the calculated value (sqrt(P x R)) and the maximum rated voltage of 75V.

Terminal Name Type Function
1 Terminal A Passive Resistor terminal – connected to one end of the resistive element through inner electrode
2 Terminal B Passive Resistor terminal – connected to the other end of the resistive element through inner electrode

Note: This is a 2-terminal passive chip resistor with no polarity. The 0603 package has terminations on opposite ends. Land pattern per IPC-7351: pad width 0.8-1.0mm, pad length 0.6-0.8mm, pad spacing 0.8-1.0mm.

Application Circuit Role Key Requirement
