CHANGJIANG

Power inductors and SMD magnetics for power-conversion circuits

About the manufacturer

CHANGJIANG manufactures inductive components primarily for modern power-conversion and power-supply circuits. Its range includes SMD inductors in different sizes, inductance values and current ratings.

The products are designed for miniaturised electronics and switch-mode converters, where low winding resistance, suitable saturation current and stable performance across the load range are essential.

The variety of available series makes it possible to select components for compact power stages in portable electronics as well as more heavily loaded converters used in industrial electronics, automation and power systems.

Applications

CHANGJIANG inductors are used mainly in power and filtering paths where efficiency, ripple-current reduction and compact component size are important.

• DC/DC converters – energy storage and current stabilisation in buck, boost and buck-boost topologies.

• Switch-mode power supplies – current filtering and ripple reduction.

• Industrial electronics – power sections of controllers and actuator modules.

• Consumer devices – compact converters on mainboards and modules.

• LED systems – converters and constant-current drivers.

• Telecommunications and IoT – efficient local power-conversion stages.

• Automotive electronics – auxiliary converters and supply filters, subject to application requirements.

CHANGJIANG products available from Maritex

The Maritex range of CHANGJIANG products focuses on SMD inductors and chokes for power-supply circuits. Models are available with different inductance values, current ratings and package sizes, making it easier to match the component to a converter topology.

Available product groups include:

• SMD power inductors.

• SMD inductors for DC/DC converters.

• Compact inductors for high power-density circuits.

• Inductive components with low winding resistance.

• Chokes for power-line filtering.

The Maritex range includes models such as FEXL0430A-2R2M, FCD43-2R2M, FNR6045S150MT and FXL0630-470-M. Inductor selection should consider inductance, rated and saturation current, DCR, switching frequency and permissible temperature rise.
