Additional Details:

The RL-3264 series from Susumu are manufactured using thin film technology, which ensures tight tolerances and low temperature coefficients of resistance. The resistor consists of a thin film resistive element deposited on a ceramic substrate, offering excellent electrical and thermal properties. The terminals are typically plated with nickel and tin for good solderability.

The '8' in the part number indicates the power rating of 0.5W and the physical size of the resistor within the RL-3264 series. The 'FN' likely indicates a tighter tolerance or other enhanced performance characteristics beyond the standard 'F' tolerance. The resistance value of 0.040 Ohms is suitable for current sensing applications where a small voltage drop is desired for accurate measurement. The typical operating temperature range is -55°C to +155°C.

When selecting a resistor, factors such as power dissipation, operating temperature, and required tolerance must be considered. Susumu provides detailed datasheets for their products, offering comprehensive information to assist in the selection process. The RL-3264-8-R040-FN offers a combination of precision, stability, and increased power handling, making it suitable for demanding applications requiring accurate current measurement or voltage division.
