Introduction
H81K1DCA is a type of through hole resistor, which provides reliable and accurate current sensing in a variety of applications, and is widely used in a wide range of industries including automotive, industrial control, test and measurement, consumer electronics, and medical. It provides a reliable and cost-effective current sensing solution for applications that require reliable, low-power consumption, and high precision.Working Principle
H81K1DCA works by using a Whisker Tension Force mechanism in a sealed vessel to detect changes in current. This mechanism consists of two whisker sources and two electrodes. The whisker sources create an electrical field, which is monitored by the electrodes. When one or more of the whiskers come into contact with a conductor, the electrical field is altered and this change is detected by the electrodes. This change in electrical field is used to measure the current flowing through the conductor and is then used to detect changes in the current.Features
H81K1DCA is designed with a number of features in order to provide reliable and accurate current sensing. It has a wide operating temperature range from -40°C to +125°C, a high input tolerance of ±10%, and a low power consumption of 0.6mW. The device also features a low self-inductance, ensuring a high signal-to-noise ratio and providing a fast response time. It has a low impedance of 33 ohm and a high response rate of 1000kHz, making it an ideal choice for high-frequency applications.Application Fields
