CFR-50JT-52-68K

The CFR-50JT-52-68K through hole resistors are a type of resistor used to limit current flow. They are usually composed of ceramic material, with two free-standing metal electrodes of the same material that span the length of the ceramic dielectric. The resistor is typically a small package, with a diameter that is usually no greater than 0.13 inches (3.3 mm).

The CFR-50JT-52-68K through hole resistors are designed to provide reliable and accurate current limiting. They are commonly used in applications such as automotive, telecommunications, power supplies, medical, and consumer electronics. The resistors\' size allows them to be discreetly placed in small or crowded electronic circuits. In addition, their low DC power requirements allow them to be manufactured with temperature-stable dielectric materials that limit transient current oscillations.

The CFR-50JT-52-68K through hole resistors use a current-limiting principle called “negative impedance”. A negative impedance is created when the resistance to current flow is greater than the applied voltage. This creates an overall impedance, which in turn limits the amount of current that can flow through the resistor. This is advantageous in circuit design since it limits the amount of heat generated by the design, and thus prevents any potential damage due to excessive heat build up.

The CFR-50JT-52-68K through hole resistors also feature an additional resistive element called a “self-resonant frequency.” This is an important feature in circuits since it helps reduce harmonic content in the signal. The resonant frequency of the resistor is the parallel equivalent of the applied voltage divided by the applied current. The resonant frequency is optimized for each resistor, and helps reduce harmonic interference and reduce power supply ripple from the source.

The CFR-50JT-52-68K through hole resistors can be used in a variety of applications, such as switching power supplies, AC line voltage smoothing, high-voltage applications (up to 6kV), voltage dividers, current measurement for motor control, over-voltage protection, surge protection, and spike protection. They are also commonly found in industrial control systems, consumer electronics, and medical equipment.

The CFR-50JT-52-68K through hole resistors are available in various sizes and configurations to meet the requirements of specific applications. They are generally rated per their temperature range, power ratings, and voltage ratings. The resistors also feature “current limiting” protection, which helps protect the circuit from overcurrent or overvoltage damage.

In conclusion, the CFR-50JT-52-68K through hole resistors are designed for a variety of applications. They are generally reliable and precise devices that provide a current limiting effect and reduce noise. They also offer the advantage of an adjustable self-resonant frequency to help reduce harmonic interference. Additionally, they offer a wide range of power and voltage ratings as well as temperature-stable dielectric materials for low DC power requirements.
