The recommended PCB layout for TNPW0402100KFEED involves using a symmetrical layout, with the resistor centered on the PCB and traces of equal length and width to minimize thermal gradients and ensure accurate resistance values.
To handle the high power dissipation of TNPW0402100KFEED, ensure good airflow around the component, use a heat sink if necessary, and follow proper PCB thermal design guidelines to prevent thermal runaway.
While the datasheet specifies a maximum working voltage, it's essential to consider the maximum allowable voltage, which is typically 2-3 times the maximum working voltage. For TNPW0402100KFEED, the maximum allowable voltage is around 1200V.
The temperature coefficient of TNPW0402100KFEED affects its resistance value, which can change by ±1% over the operating temperature range. This means that the resistor's performance may vary depending on the application's temperature conditions.
While TNPW0402100KFEED is suitable for high-frequency applications, its performance may be affected by parasitic inductance and capacitance. Ensure that the resistor is properly decoupled and consider using a resistor with a lower inductance value if necessary.
