Through Hole Resistors (THRs) are one of the most common types of electronic components used in electronics. The WW3FT909R is a THR designed for general-purpose applications. It offers excellent performance with outstanding stability characteristics, making it an ideal choice for a variety of applications.

The WW3FT909R features an oxide-coated metal film construction that offers low temperature coefficient (TC) and excellent resistance accuracy. The ceramic-core construction also provides high power dissipation and low noise characteristics. The THR has a wide resistance range, rated from 1kΩ to 1MΩ, making it suitable for many application fields.

The WW3FT909R is a low inductance THR, meaning that it will maintain its resistance even in high-frequency circuits. This makes it suitable for use in circuits which require stable, low-inductance performance, such as switching power supplies and high-frequency audio systems. It also offers excellent temperature compensation qualities which prevent it from aging over time.

The WW3FT909R is designed to be mounted through a hole on a printed circuit board (PCB) and is based on a closed loop design with a hermetically sealed glass-filled polyester film as the main body. This design offers excellent protection against external elements such as dust and humidity. It also has a low-contact resistance that increases the overall performance of the THRs.

The WW3FT909R also features a flame-resistant and corrosion-resistant construction, making it suitable for use in harsh environment applications. The THR has a high dielectric strength that enables it to withstand high surge currents, making it well suited for automotive applications. The THR also has a short lead length that reduces the risk of lead breakage.

The working principle of the WW3FT909R is based on Ohm’s law, where the resistance of the THR is proportional to the potential difference across its terminals. The current flow through the THR is then determined by the voltage and the resistance. When a voltage is applied to the THR, a current will flow through it according to the resistance value. The current will decrease when the voltage is increased and the resistance remains constant.

The WW3FT909R offers excellent performance in a variety of different application fields. It is suitable for use in switching power supplies, high-frequency audio systems, automotive applications, and harsh environment applications. It is also ideal for circuits that require low inductance performance due to its closed loop design and high power dissipation characteristics.
