Fixed inductors are an important component of circuits and are widely used in power electronic circuits. ER1840-35JR is a type of fixed inductor, which is largely used in current-limiting and voltage-limiting applications. It is especially suited for wide-band applications requiring low-impedance at high frequency.

ER1840-35JR application field

ER1840-35JR fixed inductor can be widely used in many applications, such as, amplifier circuits, voltage regulator circuits, current limiting circuits, voltage limiter circuits, AC/DC converters, high frequency rectifiers, and frequency converter circuits, etc. Due to its wide operation range frequency and high rated current capacity, ER1840-35JR is a highly suitable choice for these applications.

ER1840-35JR Working Principle

ER1840-35JR is a fixed inductor, which is a basic component that consists of a coil of insulated wire winded around a core enclosed in a case. Its core material is ferrite, which greatly improves the efficiency of the inductor when under high frequency. When a current flows through the wound coil, a magnetic field is created, and the flux (number of lines of magnetic force) of this field is increased as voltage rises across the inductor’s windings. If the inductor is connected in series with an AC voltage source, then the current through the inductor will lag the voltage of the source, which is the fundamental working principle of a fixed inductor. Due to this time-delay, the voltage across the inductor drops as the frequency of an AC power source increases, thus allowing the ER1840-35JR fixed inductor to act as a stable high frequency current limiter or voltage limiter.

Conclusion

ER1840-35JR fixed inductor is a highly suitable choice for frequency applications requiring low-impedance at high frequency. It has a wide operation range frequency and high rated current capacity, allowing it to be used in many different applications, such as, amplifier circuits, voltage regulator circuits, current limiting circuits, voltage limiter circuits, AC/DC converters, high frequency rectifiers, and frequency converter circuits, etc. The working principle of a fixed inductor is such that the voltage across the inductor drops as the frequency of an AC power source increases, thus allowing the ER1840-35JR fixed inductor to act as a stable high frequency current limiter or voltage limiter.
