Current transducers are devices that measure electrical current in devices ranging from consumer electronics to power distribution systems. The PDRV421RTJT is an example of a current transducer designed specifically for low-current, high-accuracy measurements. The PDRV421RTJT features a wide operating voltage range, low phase error, and an adjustable low-pass filter for filtering out high-frequency noise. This device is used in applications where accurate measurements of small currents are required, such as smart meters, precision power supplies, medical devices, and instrumentation systems.

The PDRV421RTJT current transducer is based on a magnetic sensing principle. This type of transducer utilizes a portion of the magnetic field that is created by the electrical current through a conductor. By passing a low-voltage reference current through a magnetic sensing element, the resulting responsive output is proportional to the current passing through the conductor. The reference current provides the conversion constant, meaning that the transducer can accurately measure a range of current based on the reference current and the similarities in operation of the transducer and the monitored conductor.

The PDRV421RTJT current transducer is designed for low-current, high-accuracy applications. It has a wide operating voltage range of 8 to 32 VDC, low phase error of ±0.4° maximum, and an adjustable low-pass filter to filter out high-frequency noise. The transducer has a conversion ratio of 50 A/V with a linearity error of ±0.2%. The PDRV421RTJT is packaged in a SOT563 surface-mount package for easy installation and has an operating temperature range of -40°C to +85°C.

The PDRV421RTJT current transducer is a versatile device suited for many applications where accurate measurements of small currents are required. It is widely used in smart meters, precision power supplies, medical devices, instrumentation systems, and many other low-current, high-accuracy applications requiring accuracy and reliability.

The PDRV421RTJT current transducer has several advantages over other current transducers. Its wide operating voltage range allows it to be used in a variety of applications. Its low phase error and adjustable low-pass filter reduce electrical noise on the transducer output, providing more accurate measurements. Its linearity error of ±0.2% ensures highly accurate measurements, and the small size of the transducer allows for easy installation and deployment.

The PDRV421RTJT current transducer is a versatile device with a wide range of applications requiring low-current, high-accuracy measurements. For applications where high accuracy is critical, the PDRV421RTJT is an ideal choice. With its wide operating voltage range, low phase error, adjustable low-pass filter, and linearity error of ±0.2%, the PDRV421RTJT current transducer is the perfect solution for any low-current, high-accuracy application.
