Resistor Networks, Arrays are widely used in various electronic circuits, such as power supply, amplifier and signal processing circuits. The RNA4A8E203JT chip is a SMD Low Current Safety Resistor Array with Full Traceability. It is designed for applications where space and component count are important. Its reliability has been proven among many electronic and automotive applications, such as input protection and current sensing.

The RNA4A8E203JT chip consists of eight independent resistors in a 4x2 array configuration. Each resistor has a value of 220 Ω ±5% with a tight tolerance of ±0.5%. The high-precision resistors are securely mounted inside the package, so there is no need for external resistor selection. It has a voltage rating of 16V and an operating temperature range from -55°C to +125°C. The chip is RoHS compliant with PPAP certificated

The chip mainly functions as a current sensing and current limiting device. Each of the eight individual resistors can provide a precise resistance value to detect the current flow in the circuit. This prevents high current from damaging the internal components, so it ensures an optimized input protection. In addition, the array also works as an isolated voltage source, which can be used to measure the voltage of a transistor or an oscillator.

The chip is widely used in various circuits, such as LED lighting, automotive engine control, power supply, power controllers, motor controllers, industrial controls, and instrumentation. Each of the eight resistors can be connected in series, which allows for high current handling capability up to 500mA in parallel. The chip can also be used for other applications such as RC networks, AC-coupling, voltage-divider, current-divider, and snubber circuits.

In addition, the chip offers excellent thermal performance for up to a 500mA peak current. The outer package is made of heat-resistant glass, and the resistors are located inside the package for additional thermal protection. Furthermore, the chip comes with a thermal protection feature which prevents it from overheating.

The chip is a highly reliable and robust component with a wide array of applications. It is designed to provide an accurate and reliable performance in challenging environments. In addition, the chip is easily configurable for a variety of applications and user requirements. With its compliant package and traceability features, it is an ideal choice for applications where space and component count are important.
