Resistor Networks, Arrays

YC162-FR-07390KL is an advanced resistor array product, whose application fields and working principles are discussed here. It is a 9-pin SMD (Surface Mount Device) resistor array, divided into 6 parallel cascaded resistors, with each resistor in series with a diode. With the help of this configuration, the YC162-FR-07390KL enjoys a great level of flexibility in use, which enables it to be applied to many different types of applications.

Application Field

Firstly, this resistor array can be used in current sensing, short circuit protection, ESD protection and general signal conditioning. For example, YC162-FR-07390KL can be used in the automotive field to detect and protect against current overloading. In this application, an audio signal is passed through each resistor, and the level of current can be measured by the control circuit to ensure the device operates safely.

Another application of the resistor array is to protect the device from ESD (electrostatic discharge) and EMI (electromagnetic interference). The 9-pin SMD resistor array is designed with a high ESD clamping voltage, making it suitable for protecting sensitive electronic components from the damage caused by ESD.

In addition to these, YC162-FR-07390KL can be applied to high-frequency power conditioning, high-current filtering, and AC and DC motor control. High-frequency power conditioning requires a resistor array with a small size, high resistivity, and low inductance. The YC162-FR-07390KL can fulfill this requirement to effectively reduce the impact of harmonic distortion on a power system.

Working Principle

The structure of the YC162-FR-07390KL is mainly composed of 6 resistors in series with 6 diodes. When a current flows through the resistor array, the resistors provide impedance, which determines the amount of current flow. The diodes further limit the current flow to a certain amount, thus protecting the system from any potential overloading. On the other hand, when the current is too low, the diodes can further limit the current, ensuring that the device will not malfunction.

In addition, the resistor array also works as a low-pass filter. As the frequency of the signal increases, the impedance of the resistor array increases, thus blocking out the higher frequencies. This property of the resistor array is especially useful for high-frequency power conditioning.

The YC162-FR-07390KL enjoys a wide application range thanks to its flexible structure and superior performance. Its low cost and large size make it an ideal choice for many different applications.
