ELECTRICAL SPECIFICATIONS²
Operating Temperature: -40 °C to + 85 °C
Frequency Range (Transmission/Reception): 370 to 510 MHz
DESCRIPTION
The VJ5301M433MXBSR ceramic chip antenna is a small
form-factor, high-performance, chip-antenna designed for
operation at 433 . It allows manufacturers to design high
quality products that do not bear the penalty of a large
external antenna, and is designed to be assembled onto a
PC board using a standard reflow process.
The VJ5301M433 is the latest in a family of products
developed by Vishay™, a world leader in manufacturing of
discrete and passive components.
The VJ5301M433 series are small form-factor, high-performance
chip-antennas optimized for industrial, automotive, and medical
applications.
Utilizing unique Vishay™ materials and manufacturing
technologies, these products when properly tuned also comply
with the MBRAI standard for portable communication.
Features
 Small outline (35 mm x 5 mm x 1.2 mm)
 50Ωunbalanced tuning interface (max. -5.7
gain¹)
 Assembled onto a PCB in the standard reflow process
 140 MHz half-power tuned bandwidth (370 to 510 MHz)
 High-reliability ceramic-oxide body construction
 Low-RF-loss, high-Q ceramic

 Reliable Noble Metal Electrode (NME) system
 Compliant to RoHS Directive 2002/95/EC
 Halogen-free per IEC 61249-2-21
 Wide operating temperature range (-40 °C to + 85 °C)
Applications
 Medical Telemetry (internal/external)
 Broadband transmission and reception
 Automotive (TPMS, etc.)
 Industrial and medical band applications
