CF14JA300K

Through Hole Resistors

The CF14JA300K is an axial leaded resistor from the through hole resistor family, which is based on a stable, high-resistance substrate material that is usually made from uniform, high-purity ceramic with a proprietary glaze. The ceramic elements are the primary body of the resistor and they are made with a metalized layer on the outside, forming a resistor element and a pattern on the inside that allows an electric current to bypass the resistor.

The CF14JA300K through hole resistor features an axial lead with a gold-plated metal tip. A lugnut in the lead makes sure the resistor isn\'t detached from its partner component. The presence of the lugnut also improves strain relief on the lead.

When selecting a CF14JA300K through hole resistor, a standard voltage rating of 350V is the most typical option. For a lower voltage rating, the number next to the \'JA\' in the resistor\'s part number should be reduced. For example, the CF14JA200K through hole resistor has a resistance of about 200V.

CF14JA300K Application Field

The CF14JA300K through hole resistor is designed to handle currents in the range of 0.5A to 2A and is widely used in power supplies, motors, switch mode supplies, heater control circuits, power amplifiers, power switching circuits, and more. It is ideal for applications that require a high resistance and robustness in the face of mechanical shock and vibration.

CF14JA300K Working Principle

The CF14JA300K through hole resistor works by having an inner core of ceramic material that acts as an insulator. The metalized layer on the outside of the ceramic provides a number of terminals that allows for electric current to flow in both directions. This resistance causes a voltage drop across the entire element, acting as a load that can be controlled and fine-tuned with the proper selection of the resistance value.

The current rating of the CF14JA300K through hole resistor is determined by the cross sectional area of the metalized layer and the total mass of the resistor. This gives the resistor the ability to handle higher current levels with a lower resistance value. The total resistance of the resistor is determined by the length of the resistor and the effective length of the terminals that can be provided on the metalized layer. Choosing the appropriate resistance ratings can help to ensure the proper performance requirements of your design.

The CF14JA300K through hole resistor is extremely durable due to the use of a clay-based ceramic material. This material provides high heat dissipation abilities and excellent electrical resistance. Furthermore, it has a low temperature coefficient which helps ensure accurate readings over a wide range of temperatures.
