Ferrite inductor WL1230

ferrite corewire-woundhigh-frequency

Product overview
Rod core ferrite coil WL1230 is a compact inductive component designed for receiving, electromagnetic coupling and frequency-specific applications. It combines a ferrite rod magnetic core with precision enameled copper winding to deliver high inductance and improved magnetic coupling in constrained PCB or module footprints.

Key notes
Performance depends on ferrite material, core dimensions, number of turns, wire diameter and circuit matching. WL1230 can be optimized for specific frequency bands and sensitivities required by industrial, automotive and communication systems. Customization is available for material, winding, dimensions and electrical parameters to meet OEM requirements.

Features

• High magnetic permeability for concentrated flux and increased inductance
• Compact 30 mm footprint suitable for constrained layouts
• Precision enameled copper winding for consistent electrical parameters
• High Q factor across intended kHz–MHz bands
• Options for varnish, epoxy or protective coatings

Applications

• AM antennas and radio receiver front-ends
• RF and wireless systems, RFID readers and identification units
• Wireless sensors, IoT nodes and smart meters
• Automotive electronics (keyless entry, TPMS, control modules)
• Industrial control systems, sensors and measurement equipment
• Communication and medical electronic devices (as applicable)

Advantages
Provides increased sensitivity and magnetic coupling compared with air-core equivalents, reduced electromagnetic losses in target bands, and compact form factor for modern electronic modules.

Disadvantages
Ferrite materials are brittle and sensitive to mechanical shock; magnetic properties vary with temperature, so material selection is critical for harsh environments. Precise winding and quality control are required and can affect production cost.

Troubleshooting & common issues

• Low inductance — check winding turns, wire diameter and core integrity.
• Weak reception — verify coil orientation, circuit matching and external interference.
• High DC resistance — inspect winding quality and solder joints.
• Temperature-related drift — select ferrite grade suitable for the operating range.
• Mechanical damage — inspect for fractures and replace damaged cores.
• Production variability — enforce tight manufacturing tolerances and testing.
