Additional Details

The RL3720WT-R033-F-0.033R resistor is manufactured using a thin film resistive element sputtered onto a high-quality ceramic substrate. This construction provides excellent stability and precision. The wide terminal design improves heat dissipation by increasing the contact area between the resistor and the PCB, lowering the thermal resistance. This is particularly advantageous in applications where the resistor is subjected to high power levels. The resistor's low TCR minimizes the effects of temperature variations on the resistance value, ensuring consistent performance in various operating conditions. The "-F" suffix denotes that the component complies with RoHS standards, indicating that it is lead-free and environmentally friendly. The specified power rating will depend on the exact dimensions of the resistor, so consulting the datasheet for specific derating information is recommended for optimal circuit design. Susumu's meticulous manufacturing processes ensure that this resistor delivers consistent and reliable performance in critical applications.
