BCN Series Thick Film Chip Resistor Arrays are used as pull-up/pull-down resistors for digital IC’s, series termination on high speed data busses, and current limit for LED displays. The series features reliable monolithic construction, nickel barrier terminations, top side marking, and concave or convex termination styles.
The BCN Series chip resistor arrays from Biltechnologies are thick‑film components offered in various widths (1.0 mm, 1.6 mm, 2.1 mm, 3.1 mm) and configurations (isolated or bussed). They provide reliable monolithic construction, nickel‑barrier terminations and options for square or scalloped edges.
The document lists standard resistance ranges, tolerances, operating voltage, power ratings, environmental limits, mechanical dimensions and ordering codes, enabling designers to select the appropriate array for pull‑up/down, bus termination or LED current‑limit applications.
