The A103J Network Resistor (9-pin) is a compact SIP (Single Inline Package) resistor array containing eight 10KΩ resistors with one common pin. It's widely used in digital electronics, especially in microcontroller circuits where multiple pull-up or pull-down resistors are required.
By integrating multiple resistors in a single package, it saves PCB space, reduces soldering effort, and offers neat, compact circuit design—ideal for Arduino, STM32, AVR, and logic gate-based circuits.
This component is commonly used in keypad matrices, LED arrays, and I2C bus pull-ups.
