PRODUCT SHOWCASE
Electronex arrives in Melbourne this May
Electronex, the electronics design
and assembly expo returns to the Melbourne Convention and Exhibition
Centre on the 10-11th of May 2023.
Electronex is Australia’s pre-
eminent exhibition for companies
using electronics in design, assembly,
manufacture and service in Australia.
The SMCBA Electronics Design and
Manufacture Conference will also be
held, featuring technical workshops
from international and local experts.
In an exciting new development,
Electronex will be co-located with
Australian Manufacturing Week, with
trade visitors now able to visit both
events on Wednesday or Thursday.
This allows visitors to see the entire
spectrum of the latest products, technology and turnkey solutions for the
electronics and manufacturing sectors.
Attending this event is a must for
designers, engineers, managers and
other decision-
makers involved in
designing or manufacturing products
that utilise electronics.
The expo will showcase a wide
range of electronic components, surface mount and inspection equipment,
test and measurement and other products and services.
Companies can also discuss their
specific requirements with contract
manufacturers that can design and
produce turnkey solutions. Register
to attend for free at www.electronex.

Nordic Semiconductors new nRF7002 companion IC for WiFi 6
The nRF7002 is a low-power WiFi
6 companion IC providing seamless
dual-band connectivity (2.4 & 5GHz).
The nRF7002 can be used together
with Nordic’s nRF52 & nRF53 series
multi-protocol SoCs and the nRF9160
cellular IoT SiP (LTE-M/NB-IoT) . But
it also can be used in conjunction with
non-Nordic host devices.
The nRF7002 brings low power and
secure WiFi to the IoT sphere. The
dual-band IC complies with Station
(STA), Soft Access
Point (AP), and
WiFi direct operation, and meets the
IEEE 802.11b, a, g,
n (“Wi-Fi 4”), ac (“5”), and ax (“6”)
standards.
It also works with Bluetooth LE,
Thread, and Zigbee. The nRF7002 supports Target Wake Time (TWT), a key
WiFi 6 power saving feature. Interfacing with a host processor is done via
SPI or Quad SPI. The IC offers a single
spatial stream, 20MHz channel bandwidth, 64 QAM (MCS7), OFDMA, up
to 86Mbps PHY throughput, and BSS
coloring.
The nRF7002 is the ideal choice for
implementing low power SSID-based
WiFi locationing when used together
with the nRF9160 and nRF Cloud
Location Services.
This is all supported by the devel-
opment kit. The dev kit includes an
nRF7002 IC and features an nRF5340
multi-protocol SoC as a host processor. The nRF5340 embeds a 128MHz
Arm Cortex-M33 application processor and a 64MHz network processor.
The dev kit includes: Arduino connectors; two programmable buttons; a
WiFi dual-band antenna and a Bluetooth LE antenna, and current measurement pins.
The nRF7002 companion IC and
dev kit are available now from Nordic’s distribution partners.

High current inductor for automotive applications
Würth Elektronik introduces
another AEC-Q200 certified SMD
inductor: the WE-XHMA. It features
an extremely high current capability of
up to 50.6A saturation current and the
ability to handle high current transient
peaks. Its design with a flat wire coil
and composite core material ensures
low copper losses and stable behavior
under temperature fluctuations.
siliconchip.com.au
The WE-XHMA is particularly suitable for use in DC/DC converters for
high current supply and FPGAs, as
well as filter applications. In contrast to conventional core materials,
the compact coil shows hardly any
temperature-dependent fluctuations
in terms of inductance and saturation current.
The higher energy density and the
compact design make it useful for
switch-mode power supplies. Furthermore, it shows a lower skin effect at
higher frequencies and the heat dissipation towards the circuit board is also
Australia's electronics magazine
better than round wire. The compact
molded magnetically shielded coils
have an operating temperature range
of -40°C to +125°C.
The WE-XHMA is available in SMT
styles: 6030, 6060, 8080, 1090 and
1510. You can also choose between
saturation currents from 9.3 to 50.6A.
Free samples for developers are provided.
