Through Hole Resistors

Through hole resistors, also known as through-hole resistors, are resistors that are mounted and soldered onto the circuit board by a hole through its body. This makes them faster to mount and more robust than their surface-mount counterparts. This type of resistors is most commonly used in industrial applications or in situations where larger power dissipation or stability is needed.The most commonly used and widely available through hole resistors are metal-oxide film resistors (MOFs). They are extremely popular due to their low cost and reliable performance. They are also relatively low in noise and self-heating and can withstand high temperature and voltage. The PF2203-4R3F1 is an example of a through-hole resistor and is designed for high-frequency applications.The PF2203-4R3F1 is a surface mount, qubits, multilayer thick-film resistor with an impedance of 4.3 Ω. It is a direct replacement for any through-hole equivalent resistor and has a temperature coefficient of ±1%/K. It is designed for high-frequency applications, with a maximum self-resonance frequency of 200MHz and a capacitance of 0.2pF, making it ideal for high-frequency applications.The PF2203-4R3F1 is a popular choice for applications such as Frequency Synthesisers, Frequency Modulators, and Other Control Devices. The resistor\'s high stability over temperature also makes it a great choice for temperature sensors, thermistors, and other temperature-sensitive components. It also can be used in power supply applications and is typically used in applications such as over-current protection devices.The PF2203-4R3F1 is also relatively easy to solder onto the circuit board, which makes it an ideal choice for designers who need a quick and reliable adapter to a circuit. The through-hole design also ensures that the resistor is well-positioned for accurate current measurement and will not easily break from thermal expansion or mechanical damage.The PF2203-4R3F1 is designed to minimize power dissipation as well as maximize power output. This is done through the resistor\'s structure, which is designed to reduce the contact surface area of the resistor by using multiple layers. This reduces the contact area and allows the resistor to dissipate heat more effectively.One of the unique features of the PF2203-4R3F1 is its low noise and high stability. This is achieved through its proprietary tantalum nitride (TaN) thick-filmed structure, which is designed to reduce electrical noise and maintain a stable impedance over a wide range of temperatures. This feature makes it ideal for precision applications such as voltage-controlled oscillators.In conclusion, the PF2203-4R3F1 is a versatile through-hole multilayer resistor that is ideal for a variety of applications. It is easy to solder, low in noise and high in stability, making it a great choice for both industrial and precision applications. Its low power dissipation also makes it a great choice for power supply applications as well as over-current protection devices.
