4610X-101-204LF

Resistor Networks, Arrays are a breed of passive components which have the advantage of combining the functions of multiple resistors. The 4610X-101-204LF (or UniOhm LR-4610X) is a popular example of this, offering a unique combination of convenience and performance. With its simple two-terminal design and versatile range of ratings, the 4610X-101-204LF serves a variety of useful electronic application fields, and has become one of the most widely adopted resistor networks on the market.

The 4610X-101-204LF is a popular TO-126 type, twenty-pin arrayed package. It consists of 10 independent resistors of identical values, each rated at 18 ohms. Not only does this make it easy to combine resistors for a larger resistance, but it also allows for fractional ohms resistance values when combining two or four resistors (for example, choosing two of the 10 resistors allows a value of 9 ohms). What’s more, all 10 resistors are available in a single package, and the pins are arranged in two columns to facilitate easy installation and replacement.

The primary application field for the 4610X-101-204LF is in power supply and power transistor switchers. As a single device, it allows for the connection of multiple transistors switching in parallel, ultimately resulting in higher currents and faster switching times. It facilitates low noise operation as well, as the equal resistance of each resistor prevents current circulation during inrush. This feature also protects the transistors from saturation and makes the resistor design simpler, resulting in fewer components on the board.

The 4610X-101-204LF is also used as an RF choke. In this application, it becomes the ideal source of continuous current, as the resistance of each resistor segment allows for appropriate impedance matching between the power supply and the load. Additionally, the simple two-terminal design eliminates the need for additional on-board components, thus providing a cost effective solution that reduces board size and component count.

The 4610X-101-204LF also makes a great choice for voltage sensing and voltage limiting. With a simple connection of the resistor array, it allows for the accurate detection of voltage levels, thus safeguarding sensitive circuits from over-voltage conditions. It is also widely used in power control circuits, allowing for easy circuit isolation and better thermal performance.

In short, the 4610X-101-204LF is a versatile resistor network capable of a variety of applications. Its easy installation and minimal component count make it an ideal choice for a wide range of applications, from power supply switchers and RF chokes, to voltage sensing and voltage limiting.
