Product catalog summary

Overview: The SEA SMD Small Emitter Antenna is designed for RF applications in the low-frequency range. It is suitable for telemetric, telecontrol, atomic watch, and PKE applications. The antenna is compact and can be mounted directly onto a PCB like other SMD components.

Mechanical Dimensions: The antenna measures 50.80 x 10.60 x 6.80 mm, with inductance values ranging from 33 uH to 470 uH.

Key Features:

Small size: 50.8 x 10.6 x 6.8 mm
High temperature stability: -40ºC to +85ºC
Wide working frequency range: 20 kHz to 150 kHz
SMD mounting capability
Custom inductance values available upon request

Electrical Specifications: The document provides a reference guide for common values at working frequencies of 20 kHz, 125 kHz, and 134.2 kHz. Sensitivity is measured with Helmholtz coils at H=8.36 App/m @125 kHz. Specific measurements can be requested from the sales department.

Catalog excerpts

SMD Small Emitter Antenna This part can be used as emitter antenna of a RF application in low frequency range and can be mounted like any other SMD component, directly to the PCB. Some use example: telemetric, telecontrol, atomic watch, PKE, etc. Size of this component compared to other existing emitter antennas is very small. - High stability in temperature (-40°C up to +85°C). - Wide working range (20kHz - 1 50KHz). - Custom inductance value under demand. Mechanical dimensions Electrical specifications Nomenclature description Working freq.: Electrical diagram and recommended pad layout mounting purposes Winding ferrite inductor Add under the chart: This chart is a reference guide for the most common required values at working frequency of 20 kHz, 1 25 kHz or 134.2 kHz. Any other inductance value at LF or tighter tolerances can be provided. Please contact our sales department for any inquiry. Sensitivity measured with Helmholtz coils H=8.36 App/m @ 125 kHz.
