ERZ-U21JP112

The ERZ-U21JP112 is a type of varistor, which is an acronym for variable resistor. It is a component that changes its resistance depending on the amount of voltage applied. Varistors are primarily used to protect circuits from transient over-voltages, as they can be used to limit the potential for sparking and other dangerous electrical concerns. The ERZ-U21JP112 is specifically designed for triggering at 12V to 14V, providing reliable protection against surges of up to 14V, but with a capacitive voltage of only 1.2V.

The ERZ-U21JP112 is a multi-layer device (MLD) that is composed of a series of metal oxide layers sandwiched between two electrodes. Each metal oxide layer exhibits a different electrical property, giving the varistor its voltage dependent properties and protection capabilities. This arrangement allows the varistor to almost instantaneously respond to changes in voltage, as the device can shift quickly between its ohmic state and its blocking state, depending on the voltage.

The ERZ-U21JP112 provides a variety of protection capabilities and applications, making it an ideal choice for various electrical and electronic systems. It can be used for over-voltage protection, voltage change monitoring, ESD (electrostatic discharge) protection, current limiting, and power optimization. Its maximum continuous operating voltage is rated at 14V, with a temperature coefficient of less than 0.1% per Kelvin. This makes the ERZ-U21JP112 suitable for use in a range of environments with different temperature ranges.

The ERZ-U21JP112 has a variety of features that make it particularly advantageous in certain applications. For instance, it has a low leakage current, enabling it to function effectively in low-leakage current applications such as computer and telecommunications equipment. It also features an ultra-low profile, making it ideal for designs with height constraints. Additionally, the ERZ-U21JP112 has a low capacitance of less than 1.2 pF, which helps improve the signal integrity of the system.

The ERZ-U21JP112 is ideally suited for a broad range of applications, from mobile phones and industrial electronics to medical equipment and automotive electronics. It is also suitable for use in consumer electronics and office equipment. Additionally, it can be used in telephone and fax machines, digital cameras, and consumer audio devices.

The ERZ-U21JP112 is a versatile and reliable solution for a broad range of applications. Its low profile, low leakage current, and low capacitance all make it an attractive choice for a variety of applications. Thanks to its excellent performance characteristics, the ERZ-U21JP112 ensures superior protection and reliable performance in even the harshest environments.
