H4255RBCA

The H4255RB is an iterative protection resistor, which is designed for use in applications where overall accuracy is of utmost importance. Due to its very low error tolerance, it is especially useful for precision applications, where steady accuracy is essential for the devices that it is supposed to protect.

H4255RB offers a resistance range of 0.001 ohms to several hundred kilo-ohms. This range allows it to be used in mostly any electronic application, ranging from audio products to precision monitoring systems.

Unlike most other resistors, the H4255RB is galvanically isolated. This is accomplished by an air gap in the resistor’s construction. With this isolation, the resistors have no outside influence, resulting in accuracy unaffected by high-frequency electrical noise or other environmental disturbances.

Further optimization of the resistors accuracy is facilitated by its proprietary construction, which uses copper oxide resistive film in combination with a conductive bridge composed of silver particles.

One of the key advantages of H4255RB is its superior accuracy, often down to 0.01% without any external bias applied. This accuracy is achieved without sacrificing necessary characteristics like temperature coefficient of resistance, noise performance or power coefficient.

Other features of the H4255RB resistor include a wide frequency range allowing its use in both digital and analog applications, high stability at both DC and AC operating conditions, and a high thermal shock resistance.

In terms of applications, H4255RB resistors are used in motors to measure current spike to adjust speed, in power supplies to balance load between phases, in medical equipment to monitor vital signs and in process automation to detect and control temperature for example. In short, the applications of the H4255RB free air gap resistor are virtually unlimited.

In terms of its working principle, the H4255RB resistor uses the electrical resistance of its copper oxide resistive film for measuring current. In combination with its conductive bridge, the resistor can accurately measure current flow and voltage. Compared to traditional resistors, which are only able to measure current, the H4255RB provides both current and voltage measurements for greater accuracy.

In conclusion, H4255RB through hole resistor provides greater accuracy than traditional resistors and can be used in a wide variety of electronic applications. Its galvanic isolation also makes it suitable for use in environments where electrical noise or environmental disturbances could affect accuracy. Its wide range of features like its accuracy, wide frequency range, high thermal shock resistance, and its proprietary resistive film construction make it well-suited for use in a variety of applications.
