Additional Details:

The RL-3264 series from Susumu utilizes thin film technology, which contributes to the resistor's tight tolerance and low temperature coefficient of resistance. The resistor consists of a thin film resistive element deposited on a ceramic substrate, providing excellent electrical and thermal properties. The terminations are plated with nickel and tin, ensuring good solderability.

The '9' in the part number indicates a higher power rating compared to the RL-3264-6 and RL-3264-8 series, while maintaining the same physical size. The 'F' denotes a tolerance of ±1%. The low resistance value of 0.004 Ohms makes it ideal for applications requiring accurate current sensing, where a small voltage drop across the resistor is proportional to the current flow. The typical operating temperature range is -55°C to +155°C.

When selecting a resistor, it is crucial to consider factors such as power dissipation, operating temperature, and required tolerance. Susumu provides detailed datasheets for their products, offering comprehensive information to aid in the selection process. The RL-3264-9-R004-F offers a combination of precision, stability, higher power handling, and compact size, making it suitable for various demanding applications.
