Through Hole Resistors

CFR-12GR-52-240K (hereafter referred to as the CFR-12K) is a type of through hole resistors specifically designed to manage the power dissipation of larger loads. They are heavily utilized in applications that require high voltage or current, such as in power supply designs, instrumentation and motor control systems. The CFR-12K is also excellent for dampening the effect of voltage spikes, which can result in damage to small-signal components.

The resistor element of the CFR-12K is comprised of a cylindrical ceramic core with a single-turn coiled nickel-chrome wire resistor. The resistor element is covered with a flame-retardant, non-conductive, epoxy-coated phenolic film, which provides physical protection as well as environmental sealing. This form of resistor is able to withstand higher voltage pitches and exhibit better short-term tolerance abilities than other types.

The CFR-12K is capable of dissipating heat more efficiently than other resistors when exposed to high voltages or currents. This is due to the ceramic core and the tight windings of the single-turn coiled wire, which provide greater surface area for heat dissipation. This allows for better heat conduction compared to other traditional cylindrical resistors.

The CFR-12K is typically used in applications where the highest level of power dissipation is needed. One example of such an application is high-voltage power supplies, which require the capabilities of a resistor that can effectively dissipate a large amount of heat. It is also commonly used in motor control systems and instrumentation where temperature exposure needs to be minimized. Other applications that require the use of through hole resistors are often those involving high voltages and currents, such as radio broadcasting and automotive electronics.

The working principle of the CFR-12K is fairly simple. The coiled wire of the resistor is encased in a ceramic core which helps provide superior heat dissipation. The voltage and current are then applied across the coiled wire, resulting in the resistor being heated up and dissipating the heat out of its ceramic core. This allows for a stable power supply and a steady electrical current, while limiting any voltage variance during high current loads.

In conclusion, the CFR-12GR-52-240K is an excellent option for applications that require a through hole resistor with a high level of power dissipation. Its ceramic core and single-turn coiled nickel-chrome wire resistors provide excellent heat transfer and superior lasting performance. Through hole resistors are commonly used in a variety of applications, such as radio broadcasting, automotive electronics and instrumentation.
