PPN320JT-73-1R

Through Hole Resistors (THRs) are commonly used components in electronic circuitry, allowing for reduced space requirements and easier signal trace routing. The PPN320JT-73-1R is one type of THR, and is primarily used in battery operated electronic devices.

The PPN320JT-73-1R has a power rating of 0.25W. It is a small and lightweight through-hole resistor that is designed to dissipate heat efficiently, as it has epoxy coating that increases the stability. In addition, it features dual functions which make it an excellent choice in battery operated circuit designs; the first being a current limiting device to protect components from instantaneous current overloads, and the second being a voltage divider.

Connections to the PPN320JT-73-1R are made using standard leaded wire. The resistor body is compact and easily fits through holes, allowing for uniform and reliable signal trace routing. Furthermore, its thermoplastic body ensures a strong connection between the leads and the board. With a temperature coefficient of ±10ppm/°C, the PPN320JT-73-1R also achieves excellent temperature stability due to its epoxy layer.

The PPN320JT-73-1R’s application fields include power conversion, DC-DC switching power supplies, consumer electronics, communication and audio equipment, data storage devices, and any device requiring reduced space requirements. Due to its miniaturized size, this THR is also ideal for applications in tight manufacturing spaces.

The working principle of the PPN320JT-73-1R is based on Ohm’s law; the resistance of this THR is directly proportional to the applied voltage. This property allows the PPN320JT-73-1R to be used as a current limiter, by limiting the voltage of a device by acting as a voltage divider. This ensures that a specific, predetermined load current can flow through the device and not exceed the specified amount.

The PPN320JT-73-1R is an excellent choice for through-hole resistor requirements in battery operated electronic devices, thanks to its small, lightweight design and dual functions. With its epoxy coating, efficient heat dissipation, and temperature coefficient of ±10ppm/°C, the PPN320JT-73-1R meets high requirements for stability, durability, and reliability.
