Inrush current limiters (ICLs) are passive components used to minimize high inrush currents that occur at the moment a circuit or device is powered up. PTCEL13R251NBE is an example of a most common ICL.

When a system powers up, it often generates inductive surges, which manifest as large peaks of current that can take up to one minute to reach their peak value. An ICL limits these peaks to as low as fractions of an ampere. This limits the energy drawn from the source, and thus protects connected components from power surges.

The PTCEL13R251NBE is a surface mount ICL that is designed to reduce inrush current in low-medium voltage applications. It is a thermistor-based device made with a ceramic body and radial lead that can conduct high current inrush protection. Its resistance is especially specified at high or low temperatures to maintain good performance even in harsh environment with extreme temperatures.

The PTCEL13R251NBE’s resistance is highest at low temperatures, and lowest when it is wired to the circuit. As the temperature of the device increases, its resistive value steadily decreases. This decrease creates a path for current to flow, and limits the peak current to the level specified on the device’s datasheet.

The PTCEL13R251NBE is most commonly used to protect equipment from power surges, and can be found in a wide range of applications. It is commonly used in transformer-based power supplies, DC-DC converters, rectifiers, lighting ballasts, and many other applications that require protection from overcurrent. It is preferable to many other devices because it is small and lightweight, making it easy to install and maintain. It is also relatively cheap, making it an affordable protection option.

The PTCEL13R251NBE is a reliable inrush current limiter with performance suitable for a number of applications. It reliably protects the connected equipment and components from power surges and helps to reduce power consumption by limiting inrush current. This device is small and lightweight, which makes it more preferable than other types of protection. The PTCEL13R251NBE is a cost-effective and reliable way of protecting circuits and components from possible damage and overcurrent.
