WL1225 Ferrite Coil Antenna

Product catalog summary
General Description
This document describes the WL1225 Ferrite Coil Antenna, a magnetic receiving antenna designed for applications such as AM Broadcast, LF RFID at 125KHz and 134.2KHz, Smart Meters, and Sensor Receivers. It features a compact size, high sensitivity, and low loss, utilizing a Mn-Zn or Ni-Zn ferrite core with enameled copper winding.
Mechanical Specifications
The antenna uses a rod or slab rectangular ferrite core with dimensions of 25 mm in length and 12 mm in diameter/width with a tolerance of ±0.5 mm. It includes 10.5 turns of enameled copper wire with a diameter of 1.0 mm. The overall dimensions are 12 x 25 x 10 mm, and it weighs 15 g.
Electrical Characteristics
Tested at an ambient temperature of 25℃ and humidity of 45-75% RH, the antenna has an inductance of 1 ± 10% at 1.02 kHz. The DC resistance and unloaded quality factor are specified, with a resonant frequency available optionally. Sensitivity is measured in mV/μT at target frequencies.
Operating & Environmental Ratings
The antenna operates between -40℃ and +85℃ and can be stored between -45℃ and +105℃. It withstands relative humidity from 5% to 90% non-condensing, vibration resistance from 10 to 2000Hz at 10G, and shock resistance at 30G for 11ms. It complies with RoHS and REACH standards.
Reliability Test Standard
Includes temperature cycling, thermal humidity aging, solderability, wire pull test, and ferrite core drop test, ensuring no cracks or significant drift in parameters.
Test Equipment List
Includes LCR Digital Bridge Meter, Frequency Signal Generator, Standard Magnetic Field Source, and Digital Caliper/Micrometer.
Outline Drawing Requirement
Requires all dimension marks with tolerances, lead out position, winding region mark, and ferrite core boundary.
Packing Specification
Packed in anti-static bags or trays with 200 pieces per package, labeled with model, quantity, and date code.
Disclaimer
All parameters are measured under standard test conditions. Sensitivity data is a reference value, and actual performance may vary based on matching circuits and housing metal interference. Specifications are subject to change without notice.
