The R80W-2K2 is a surface-mount, high-reliability, low-cost, resistor-attenuator array module designed with an integrated 40-terminal SMT package. It promises to deliver supreme performance while requiring minimal space constraints, thus enabling efficient multi-frequency band applications in RF communication and power electronic systems. This part of SR Passives resists soldering surface damage by featuring a Pb-free, matte Tin shielding over a Cu-Sn alloy base material. It also offers EMI suppression, impedance matching, and excellent temperature stability. From the electrical point of view, the R80W-2K2 delivers low insertion loss and high isolation, while keeping constant resistance ratios selecting up to eight resistors from a single module. Finally, its wide frequency range from DC to 3GHz extends the possibilities for communication and power system designs.
