In engineering and electronics, through-hole resistors are an essential building block of a variety of electrical circuit designs. Resistor components, which are usually tiny cylindrical disks, angle or flat strips, are attached to the circuit board with leads protruding through pre-drilled holes. In comparison to surface mounting techniques such as Surface-mount technology (SMT) or flip-chip technologies, through-hole mounting and soldering offers better durability, especially for high vibration or extreme shocks and temperature applications. When properly specified, through-hole resistors provide reliable performance that is easy to troubleshoot and repair when necessary.

WW12FT35R7 is designed for through-hole resistor applications, such as measuring the current of a DC power source, measuring electric signals, electromagnetic interference suppression, and voltage regulation. The WW12FT35R7 uses solid filled polypropylene film as the resistor element which is supported in non-flammable and high temperature-resistant plastic components.

WW12FT35R7 uses a tantalum-compounded resistor element to offer superior performance and accuracy over other through-hole resistors. The metal alloy composition of the resistor element ensures long-term durability and stability under various uses. This makes the WW12FT35R7 ideal for applications where variable load or temperature changes may be encountered. The WW12FT35R7 boasts a temperature coefficient of less than 0.2%/C maximum, and can be used for applications in the temperature range of -65°C to +165°C.

In terms of working principle, the WW12FT35R7 employs a bridge-like resistance network, which works very much like a variable resistor. Basically, the resistance of a individual section of the bridge is adjusted by a thumb wheel or knob on the left side of the resistor. This action enables the user to change the bias voltage of the network, thus varying the resistance of the circuit. This type of network enables the designer to easily and accurately control the total resistance of the component.

In applications where the exact resistance of the component is unknown or unknown, WW12FT35R7 can be used in series or parallel with other resistors to achieve a desired effect. The WW12FT35R7 also possesses a remarkable self-heating capability. This means that, even when coupled with other resistors, the WW12FT35R7 will remain relatively cool under normal operation. This makes it well suitable for intensive applications where maximum power is required, such as power amplifiers and switching regulator circuits.

To conclude, the WW12FT35R7 is a versatile and reliable through-hole resistor ideal for applications in different industries, such as digital signal processing, automotive, lighting, medical electronics, power, and industrial. It is robust, easy to mount, and can be easily adjusted for different power ranges. Through its high consistency and low temperature coefficient, WW12FT35R7 provides designers with a reliable and cost-effective resistor solution for their designs.
