MFR-12FTF52-30R9

Through Hole Resistors are used in a wide variety of electrical and electronic circuits throughout many industries due to their ability to provide precise resistance values and current ratings. The MFR-12FTF52-30R9 is a through-hole resistor from the MFR series of resistors manufactured by Ohmite. The MFR-12FTF52-30R9 is specifically designed to meet the needs of military, aerospace, defense, and telecommunications applications.

The MFR-12FTF52-30R9 resistor is made from a ceramic material and has a total resistance of 30Ω, with a tolerance of ±1% and a maximum power rating of 1 watt. It has a temperature coefficient of ±50ppm/°C and can operate between the temperatures of -55°C and +150°C. The lead material is coated with nickel and is rated to withstand temperatures up to 150°C. Additionally, the resistor is rated to withstand pressures up to 25 psi.

As with most through-hole resistors, the MFR-12FTF52-30R9 receives power through two soldered pins on its printed circuit board. However, it also contains two additional pins on either side of the resistor, which provide additional wiring and grounding options.

The primary component of the MFR-12FTF52-30R9 is carbon. This material is used to create an electrical resistance path within the resistor, which affects the amount of current that can pass through it. The carbon used in the MFR-12FTF52-30R9 has an unusually high resistance value and can dissipate heat from the resistor very efficiently.

In most applications, through-hole resistors require additional cooling or current limiting features due to their external design. The MFR-12FTF52-30R9 features a thermally conductive substrate, which allows for improved cooling and thermal management. Additionally, the substrate material is fire-resistant and reduces the hot spots caused by excessively high current flows.

The MFR-12FTF52-30R9 features a low-resistance connection, or “guard ring”, which minimizes the electrical noise generated by the resistor, suitable for applications in which unwanted electrical signals must be minimized. Additionally, the guard ring has a voltage reference terminal, which can be used to ground the resistor in applications where it is needed.

The MFR-12FTF52-30R9 is a versatile resistor suitable for many applications in the military, aerospace, defense, and telecommunications industries. Its high resistance value and fire-resistant substrate make it an ideal choice for applications that require a robust resistor capable of dissipating large amounts of heat without failing or causing excessive hot spots. Additionally, its guard ring and voltage reference terminal allow for a reduced rate of electrical interference in sensitive equipment.
