The thermal resistance of the TGHEV5R00FE is not explicitly stated in the datasheet, but according to Ohmite's application notes, the thermal resistance (RθJA) is typically around 10-15°C/W for this series of resistors.
While the TGHEV5R00FE is a high-power resistor, it's not specifically designed for high-frequency applications. Ohmite recommends using their HF-series resistors for frequencies above 100 kHz. However, if you must use the TGHEV5R00FE, ensure you derate the power rating accordingly to avoid self-resonance and other high-frequency effects.
Ohmite recommends using a soldering iron with a temperature of 250-270°C (482-520°F) and a solder with a melting point of 180-200°C (356-392°F). Apply a small amount of solder to the resistor leads and PCB pads, and ensure the soldering time is less than 3 seconds to avoid overheating the component.
Yes, the TGHEV5R00FE is RoHS (Restriction of Hazardous Substances) compliant, meaning it meets the European Union's directive on the restriction of certain hazardous substances in electrical and electronic equipment.
Ohmite recommends a PCB layout with a minimum of 0.125 inches (3.18 mm) of clearance around the resistor body to ensure proper heat dissipation and to prevent electrical shorts. Additionally, use a thermal relief pattern on the PCB to improve heat transfer and reduce thermal stress on the component.
