The Tamura LA03P021S05 is an open-loop Hall effect current sensor module designed for precise bidirectional AC/DC current measurement up to 21A. This single-channel component offers a robust solution with a typical accuracy of ±0.7% and linearity of ±1%. Its ratiometric voltage output, with a sensitivity of 100mV/A, allows for straightforward integration into various system designs. Operating from a 4.5V to 5.5V supply, the LA03P021S05 exhibits a wide frequency response from DC up to 300kHz and a rapid 1µs response time. The through-hole mounting type ensures secure installation in applications across industrial automation, power supplies, and electric vehicle systems. This module operates reliably within an extended temperature range of -40°C to 110°C.
