Vishay provides a recommended PCB layout and land pattern in their application note AN10343, which can be found on their website. It's essential to follow these guidelines to ensure proper thermal performance and reliability.
Vishay recommends using a thermal interface material (TIM) with a thermal conductivity of at least 1 W/m-K. The TIM should be applied evenly and thinly (typically 0.05 mm to 0.10 mm) to the base plate of the resistor. Vishay also provides a list of recommended TIMs in their application note AN10343.
The maximum allowed voltage derating for the TLHR4400-AS12Z is 80% of the rated voltage. This means that if the rated voltage is 4400 V, the maximum allowed voltage derating would be 3520 V. However, it's essential to consult the datasheet and application notes for specific derating guidelines.
Vishay provides safety certifications for the TLHR4400-AS12Z, including UL and IEC. However, it's essential to ensure that the specific certification requirements for your application are met. Consult the datasheet, application notes, and Vishay's website for more information on safety certifications and compliance.
Vishay recommends storing the TLHR4400-AS12Z in its original packaging, away from direct sunlight, moisture, and extreme temperatures. When handling the component, use anti-static wrist straps, mats, or other ESD protection methods to prevent damage. Avoid touching the component's leads or body to prevent contamination and damage.
