Through Hole Resistors

The SPS7R68J is a through-hole resistor. It can be used in a variety of applications requiring a reliable and stable resistive element. The SPS7R68J is a device composed of a ceramic substrate, a ceramic body and a lead/lead frame. The shape of the resistor element is a continuous spiral. With this structural configuration, the resistor is more resistant to vibration, shock and thermal cycling. Additionally, the SPS7R68J provides higher power dissipation than that of a standard four-coned resistor.

Application Field

The SPS7R68J resistor is suitable for high-power applications such as power supplies, home appliances and automotive systems. It is also widely used in telecommunications, manufacturing and test instruments.

For applications involving pulse loading and noise reduction, such as in telecommunications and medical applications, the SPS7R68J provides superior performance in the form of a high-precision, low-impedance resistor. In addition, for high-voltage applications, the device provides effective resistance in the order of a few tens of kilo-ohms, and also provides considerable overvoltage protection.

The SPS7R68J is ideal for applications where noise reduction and safety are required. The resistor can be used in sensing and control applications, such as for voltage and current control in power circuits, as well as in waveform shaping, surge protection, overvoltage protection and filtering.

Working Principle

The SPS7R68J is a four-terminal resistor. Its design consists of a ceramic substrate, a ceramic body and a leadframe. The resistor is a continuous spiral in shape with an insulating bonding wire between the turns for insulation. The ceramic substrate provides mechanical stability, thermal tracking and increased power handling capabilities. The ceramic body provides vibration resistance, shock protection and improved thermal cycling.

The resistor is designed to be physically stable under these parameters. Its physical properties are also optimized for proper operation in any environment. The resistor has a two-terminal design, with each terminal allowing the connection of one of the two input signals (either voltage or current). The two resistors are placed in series with one another, connecting both input signals with the same resistor.

At the output, the total resistor will then be measured and will form a resistance that is the sum of the two resistors. The current will flow in the direction of the resistance in parallel, as it increases from one end of the resistor, to the other.

The resistor will be configured to provide a predetermined resistance. In most cases, the resistance will be chosen to provide a predetermined voltage or current level, which is used by various applications to protect circuitry or control motors. The SPS7R68J is designed to sustain power up to 1.6W. With its two terminals in series, it can provide a resistance range from 10Ω to 4KΩ, depending on the application requirements.

In addition to the high-precision control, the resistor is also a low-noise device. It uses low inductance to reduce the amount of noise created in the circuitry. It also has a low capacitance and low parasitic inductance. This allows for better noise immunity and better overall electrical performance.

Conclusion

The SPS7R68J is an ideal choice for a wide variety of applications requiring a reliable and stable resistive element. It provides superior performance in terms of precision, low impedance, high power handling and low noise. It is suitable for high-power applications such as power supplies, telecommunications, home appliances, manufacturing and test instruments. Its two-terminal design and low parasitic inductance allow for effective noise immunity and improved electrical performance.
