Through hole resistors refer to resistors that are designed for installation on a printed circuit board (PCB) with a hole that fits terminal leads or pins of the resistor. Through hole resistors typically have ceramic or metal body packages, and offer the advantage of allowing more current to flow than surface mount resistors, as well as better heat dissipation. The MFR200FRF52-20K through hole resistor is a specialty resistor used to protect sensitive electronic circuits and is designed for high frequency applications.

The MFR200FRF52-20K is a through hole coated metal film resistor that features a metal film element, insulated by cement or epoxy overcoat and constrained in an all-metal, hermetic, fire-proof environment. This makes it a current limiting resistor with superior high frequency performance due to its short lead length. The MFR200FRF52-20K through hole resistor comes in a 5mm x 20mm package and features 20K ohms of resistance.

The MFR200FRF52-20K through hole resistor\'s chief application field is in high frequency switching power supplies where current control and circuit protection is necessary. Its high frequency response and fire-proof construction provide superior performance for these power supply applications. It can also be used in radio frequency (RF) circuits and various other high speed switching power supplies and circuit protection applications. For such usages, the MFR200FRF52-20K exhibits high speed transistors switching, low resistance component for soft-start circuit using SMD, high speed power amplifier and high frequency amplifier.
