664A1002BLF Description

The 664A1002BLF from TT Electronics / BI Technologies is a high-precision, surface-mount resistor network designed for demanding electronic applications. This 4-resistor array features a compact 8-SOIC package with dimensions of 0.193" x 0.154" (4.89mm x 3.90mm) and a low-profile height of 0.069" (1.75mm), making it suitable for space-constrained PCB designs. Each resistor offers a 10kΩ resistance with an ultra-tight tolerance of ±0.1% and a low temperature coefficient of ±25ppm/°C, ensuring stable performance across varying environmental conditions. The isolated circuit configuration and ±0.1% resistor matching ratio further enhance signal integrity, while the ±5ppm/°C resistor-ratio drift guarantees long-term reliability.
