Ferrite inductor WL1230

ferrite corehigh-frequencylow-frequency

Overview
Rod-core ferrite coil WL1230 is an inductive component for reception, magnetic coupling and frequency applications. It uses a ferrite rod as the magnetic core and enameled copper winding to provide compact high inductance. Ferrite materials increase magnetic permeability to concentrate the magnetic field and improve signal behaviour.

Key points

• High magnetic efficiency and stable inductance
• Compact, lightweight construction
• Customizable ferrite material, winding, wire diameter, dimensions and electrical parameters
• Suitable for low and mid frequency bands with high Q-factor and low power consumption

Applications

• AM antennas and radio receivers
• RF and wireless communication devices
• RFID readers and identification systems
• Wireless sensors and IoT devices
• Smart meters and metering communication
• Automotive electronics (keyless entry, TPMS, control modules)
• Industrial sensors, measurement instruments and control systems
• Medical devices and other OEM electronics

Performance and Design Notes
Rod-core ferrite coils improve magnetic coupling and reception sensitivity compared with air-core designs. Performance depends on ferrite composition, core size, number of turns, operating frequency and circuit matching. Appropriate material selection (MnZn for lower frequencies, NiZn for higher) and careful design ensure sensitivity, low losses and thermal stability.

Customization
Manufacturing supports tailored rod length, ferrite composition, wire gauge, number of turns, encapsulation and mounting to meet OEM or industrial requirements.
