Additional Details:

The TDH35H25R0FET has a resistance value of 25 Ohms. It is designed with a thick film resistive element on a ceramic substrate. The full encapsulation ensures that the resistor element is protected from moisture, dust, and other contaminants, improving the long-term reliability of the resistor. The non-inductive design is achieved through a special winding or trimming pattern of the resistive element. This minimizes the inductance of the resistor, making it suitable for high-frequency applications where inductive effects can be detrimental to circuit performance. The resistor is designed to withstand high pulse loads, making it suitable for applications with surge currents or transient voltages.

Ohmite's TDH series resistors are known for their high-quality construction and reliable performance in demanding applications. The full encapsulation of the TDH35H25R0FET provides enhanced protection and makes it a suitable choice for applications where environmental factors are a concern.
