Through Hole Resistors form an integral part of electrical and electronic circuits. The use of these devices enables the user to create connections that are resistant to electrical current. Among them, the OK1035E-R52 is a relatively new device developed by Ohmite and is an off-state resistor designed for use in the electronic field. This component is capable of providing high precision output signals and high voltage stability while working efficiently at low power levels. The resistor is used for resistor applications, power conditioning and signal conditioning.

The OK1035E-R52 is a low power through hole resistor designed to dissipate voltage in the range of 1/2 to 1 watt. It is a robust constructed component, featuring a power rating of 350mW and a very low thermal resistance of 0.2 °C/W. This component is designed to act as a base resistive element in AC and DC circuits. It has excellent temperature coefficient of resistance, thermal stability, electrical characteristic and long-term reliability. This component also offers a high working voltage capability ranging from 10V to 200V and is suitable for effective noise filtering in microwave noise applications. The operating temperature range for this component is from -55°C to 150°C.

Moreover, the OK1035E-R52 is comprised of two or more glass encapsulated NTCs (negative temperature coefficient), which exhibit an inverse relationship between electrical resistance and ambient temperature. These NTCs are made up of a combination of sintered glass or epoxy-filled ceramic resistors, and their sensitivity to the ambient temperature and the resistor’s thermal time constant is very low. These components are commonly used in controlled environments, due to their high accuracy and absence of surface current, as these NTCs are relatively immune to electric fields. The OK1035E-R52 are used in variable power applications, which require a range of wattages from 1/2 watt to 2 watts depending on the application.

In addition to controlling current, the OK1035E-R52 is also used to limit the maximum current that can flow through a circuit. This is achieved through the use of two steeply-tapered glass encapsulated NTCs, which act together to limit the current passing through the circuit. The current is limited by increasing the resistance of the NTCs as the current increases until it reaches the specified maximum limit. This design affords greater control to the user over the current flow, which in turn enhances the quality and reliability of the electronic circuitry.

Beyond the resistive element of the resistor, the OK1035E-R52 also features other properties. Its low thermal resistance of 0.2 °C/W provides efficient dissipation of power, and its high working voltage capability enables the device to operate without problems in high potential systems. The resistor also features an isolation system, which allows it to operate in high-voltage environments without creating any safety risks. The capacitor in the resistor also acts as a filtering function, and can be used as an EMI filter in high frequency applications.

In conclusion, the OK1035E-R52 is an excellent through hole resistor. It features a low power, highly reliable construction and has a wide range of applications. Its low thermal resistance and high operating voltage capability enables the resistor to be used in controlled condition and also to provide effective noise filtering in a variety of applications. Its low cost and easy installation makes it a preferred choice for many electronic designers. Thus, the OK1035E-R52 can be used in a variety of electronic circuits effectively and reliably.
