DESCRIPTION
The VJ5301M433MXBSR ceramic chip antenna is a small
form-factor, high-performance, chip-antenna designed for
operation at 433ꢂꢃꢄꢅ. 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.
Wide operating temperature range (-40 °C to + 85 °C)
Applications
Medical Telemetry (internal/external)
Broadband transmission and reception
Automotive (TPMS, etc.)
The VJ5301M433 is the latest in a family of products
developed by Vishay™, a world leader in manufacturing of
discrete and passive components.

FOOTPRINT, MECHANICAL AND PCB DIMENSIONS
The antenna footprint and mechanical dimensions are presented
in Figure 7. Optimal tuning is adjusted according to PCB layout.
For additional mechanical support, it is recommended to add one
drop of heat curing epoxy glue.
The glue dot should not overlap with any of the
soldering pads.
Apply the glue dot at the center of the antenna.
The glue dot area secures the chip firmly to the PCB.

VJ5301M433 ASSEMBLY GUIDELINES
1. Mounting of antennas on a printed circuit board should
be done by reflow soldering using the profiles shown
(Figures 8, 9, and 10).
2. In order to provide the adequate strength between the
antenna and the PCB apply of a dot of heat cured
epoxy glue in the center of the footprint of the antenna
prior to soldering the antenna to the board. An example
for such glue is Heraeus PD 860002 SA. The weight of
the dot should be 5 mg to10 mg.
