4820P-T02-223 Application Field and Working Principle

The 4820P-T02-223 is a four-terminal resistor network that has been specifically designed for use in printed circuit boards, wireless, and automotive applications. It is a miniaturized design which makes it ideal for space-constrained applications. The network\'s configuration allows it to provide reliable circuit protection, voltage stepping, and impedance matching. The device is rated up to 1.5 volts and 200mA.

This four-terminal resistor network relies on two precision resistors in parallel that are connected between two terminals. Its design allows for precise current distribution between the two terminals. By varying the voltage between the two terminals, the unequal current distribution causes the resistors to dissipate unequal amounts of power. This enables the desired circuit protection, voltage stepping, and impedance matching.

The network is composed of a base member containing two precisely matched parallel resistors and non-degenerative resistor elements, an outer cover, and four terminals. This combination of components allows the device to protect the circuit from any excessive voltage or current while allowing it to still function as desired. Additionally, the outer cover provides an effective electromagnetic shield from any outside interference.

The device offers a very reliable performance with a guaranteed ±10% tolerance. It also features low power consumption and minimal heat loss. The device is extremely long-lasting and durable, with a reliability level of over 200,000 hours tested at 1mA load. Its resistance range is 0.03 ohms to 3.3 ohms, with a total power range of 0.225W to 3W.

The device is also designed with a high-temperature solder reflow process that is highly reliable and can withstand high temperatures up to 250°C. Additionally, the 4820P-T02-223 is RoHS compliant and is highly resistant to vibration, shock, and any other environmental factors.
