A 4609X-101-203LF Resistor Network, or Array, is a series of electrical resistors wired together and issued in an integrated circuit format. Resistor networks provide a symmetrical “pie network” of resistors in a single package, such as Bussed R-Networks and Isolated R-Networks.

The 4609X-101-203LF Resistor Network is an 8-resistor surface-mount part measuring 0.150” square and 0.050” thick with four mounting pads at 0.100” centers. This part is RoHS compliant, compatible with lead-free soldering processes and suitable for use in commercial and industrial applications.

The 4609X-101-203LF is a single 8-resistor network on a ceramic substrate in the ratio of 1:13:19:37:61:121:200:336 and features a common connection on the circuitry in addition to eight individual outputs. This isolated surface-mount network was designed for use in low-voltage, RF and digital logic applications, replacing individual components when small size and maximum circuit density is desired.

The 4609X-101-203LF is ideal for high frequency and ultra-high frequency circuits, with the ability to reject any harmonic frequencies that are not in its pre-calibrated ratio. This resistor network also provides excellent noise performance in low-level signals circuits, with a typical input-output isolation of 43dB. The 4609X-101-203LF offers a high resistance per package with maximum power dissipation of 500mW and a wide operating temperature range of -55 to +125°C.

In terms of working principle, a resistor network functions using two distinct characteristics – linear resistors, and non-linear resistors. Linear resistors create a constant voltage drop, regardless of the current flowing through it, and are primarily employed for voltage division & amplification, as in the 4609X-101-203LF. Non-linear resistors, on the other hand, use a range of resistors to create a curved transfer curve, and are used for audio applications, such as in shielded headphones or audio mixing boards.

The 4609X-101-203LF Resistor Network is suitable for a wide range of commercial and industrial applications due to its small size and maximum circuit density, and its noise performance and rejection of harmonic frequencies make it a highly versatile electrical component.
