Through Hole Resistors

Through hole resistors, also known as through-hole resistor packages, are a form of electronic component. Through hole resistors are designed to be installed in printed circuit boards (PCB) in through-hole technology, rather than surface mounted devices (SMD) which are designed to be soldered to the surface of the PCB. Through hole resistors provide electromagnetic shielding, making them ideal for applications where radio frequency (RF) energy must be blocked or absorbed. The main purpose of a through hole resistor is to limit the current flow in circuits but it can also be used for other purposes such as voltage division, coupling of signals, timing, current-limiting, and protection.

The PF2203-4R7F1 through hole resistor is a small, surface mount, anti-shift passive component. The component is designed for low cost, automated production, with a guaranteed high yield of quality components. The core characteristics of the PF2203-4R7F1 are the low temperature stability, excellent electrical insulation, resistance to electromagnetic interference, and high packing density.

The PF2203-4R7F1 is constructed from a thermally conductive phenolic resin body, containing interior interconnecting pins that provide stability and insulation. The component is designed for automated reflow soldering and is supplied in a tape and reel package for this purpose. The roll is fitted with a protective cover to ensure that the pins remain protected from damage during production and transport.

The PF2203-4R7F1 is a four-terminal resistor package, with additional electrical connections provided by the through hole. This allows for a wide range of options in terms of current flow, including bridges, shunts, topside-contacts, etc. The resistance value range of these components is typically between 25∆ and 200 Ω, and the temperature range is generally between 55 and 175˚C. These components are preferred for surface mount applications because of their high dielectric strength and low inductance.

The PF2203-4R7F1 through hole resistor works using Ohm\'s Law. According to this law, current is equal to voltage divided by resistance. This means that when a voltage is applied across a fixed value of resistance, the current will be proportional to this voltage. The PF2203-4R7F1 is designed to maintain the resistance value that is given in its packaging, across a wide range of temperatures. This means that the current will be the same for a given voltage, regardless of the environmental temperature.

The PF2203-4R7F1 through hole resistor is ideal for use in a variety of applications such as power supplies, motor control, microelectronic circuits, industrial automation equipment, telecommunications, RF antennas, home theater systems, digital audio and video products, automotive electronics, and medical electronics. These components are also used in vibration detection and cooling systems.

The PF2203-4R7F1 has proven effective for use in a variety of high-power applications due to its ability to handle very high heat loads. The component can also tolerate a wide temperature range from 55 to 175˚C, making it an ideal choice for outdoor or hostile environment applications. The component is also used in applications that require radio-frequency suppression, such as TV or antenna systems. Its compact size allows it to be integrated into any kind of PCB, either in a single layer or in multi-layer designs.

In summary, the PF2203-4R7F1 is a through hole resistor package that comes with a surface-mounted construction, excellent electrical insulation, and multiple electrical connections. This component is ideal for many different applications, due to its temperature stability, wide temperature range, and high dielectric strength. Its small size makes it easy to integrate into any PCB design, making it an ideal choice for high power and RF applications.
