Resistor Networks, Arrays

Resistor networks are common electronic components that act as voltage and current dividers, buffers and impedance matching devices. These components are ideal for enabling the user to precisely control and adjust electrical signals in any specific application. The 4607X-101-562LF is a part of Resistor Networks, Arrays product offering from Thorlabs. It is a surface-mount SOIC-8 package containing a two-terminal resistor network that consists of four 562-Ohm, 5% tolerance resistors and one 150-Ohm, 5% tolerance resistor.

Application Field

The 4607X-101-562LF is a general-purpose, low-cost resistor network typically used in many applications including drive circuits, gain-adjustment, and voltage level shifting. It is especially useful in low-voltage systems, such as those powered by single or multiple batteries. Further, the low-profile SOIC-8 DIP package lets users mount the resistor network in the shallow parts of printed circuit boards, enabling them to achieve small PCB size and save board space.

Working Principle

The 4607X-101-562LF features a 2-terminal array of five 5% low-tolerance resistors. The internal connections of this resistor array are two 562-Ohms resistors in series, connected in parallel with three 562-Ohms resistors, and with a single 150-Ohm resistor connected in series. The two series resistors have a combined resistance of 1124 Ohms, and the three in parallel have a combined resistance of 187 Ohms. The single 150-Ohms resistor across the two series resistors forms an internal voltage divider. Since the 150-Ohms resistor is connected in series, the voltage drops across each series resistor is in proportion to their resistances. This allows the 4607X-101-562LF to divide an input voltage into two equal parts, or sense the voltage across the elements in the resistor array.

The 4607X-101-562LF has a low-tolerance of 5%, meaning closely matched resistors reduce voltage division errors. This precision makes it ideal for use in many analog control circuits for voltage-level shifting, current-state adjustment, and gain-adjustment. Additionally, the low profile SOIC-8 DIP package ensures it can fit into shallow parts of boards. It also allows for efficient mass production on automated assembly machines.

Conclusion

The 4607X-101-562LF from Thorlabs is a low-cost two-terminal resistor network specifically designed for general-purpose design applications. It has a low-profile footprint on an SOIC-8 DIP package that lets the resistor network fit into shallow parts of printed circuit boards. It consists of four 562-Ohms and one 150-Ohms resistors with 5% tolerance. The 4607X-101-562LF can divide an input voltage into two equal parts, or sense the voltage across the array elements, enabling users to precisely adjust the voltage levels for various applications.
