Additional Details

The 899-3-R390 consists of 8 isolated resistors, each with a resistance value of 39 ohms. The tolerance is typically ±2% or ±5%, and the power rating is usually around 0.125W per resistor or higher depending on the specific datasheet. The SIP package simplifies insertion and soldering processes. The pins are spaced 0.1 inches apart. The thick film construction ensures stable resistance values over temperature and time.

The resistor network is often used to provide pull-up or pull-down resistors for microcontroller or FPGA inputs. It minimizes component count and reduces the number of solder joints, improving overall system reliability. The 899 series is a common choice for many applications due to its versatility and ease of use.

Proper handling and soldering techniques are essential for reliable performance. Care should be taken to avoid excessive bending of the leads. The recommended soldering temperature and dwell time should be followed to prevent damage to the resistor network.
