PRODUCT BRIEFS
Noise-reducing material
SABIC (Riyadh, Saudi
Arabia) announced their
LUBRILOY N2000 compound,
a new internally
lubricated material for
prevention of buzz-squeak-rattle (BSR) noise in automotive
interiors. The new LNP compound is based on an amorphous
blend and offers both molded-in color capability and paintability.
SABIC states that the proprietary, compatibilized olefinic
alloy is free of silicone and polytetrafluoroethylene
(PTFE) and that by replacing standard PC/ABS with this material,
automotive OEMs and suppliers can significantly reduce
friction and stick-slip behavior between molded parts to limit
or prevent unwanted noise. Additionally, the new material can
reportedly be used in consumer electronics applications
where reduced friction or improved wear is required.

Cartridge fuses
Littelfuse Incorporated's (Chicago,
Illinois) new 607 compact cartridge
fuse series is now available. The fuses
carry a rating of 500Vac/Vdc with
current ratings from 40A to 63A and
a 10,000A interrupting rating. The
company states that the 607 Series is designed for overcurrent
protection applications while also providing a robust solution
for demanding high-voltage power supply circuits. The 500V
fuse rating is suitable for both AC and DC inputs. Littelfuse also
claims that a with new 10mm x 32mm cartridge body requires
less board space than previous designs that used multiple lower-current-rated
fuses in parallel, which means designers can
reduce the board space they reserve for protection components
when designing high-wattage equipment.

Impedance testers
Rohde & Schwarz (need location)
launches its new LCR
meter family of high-performance
general-purpose impedance
testers. The LCX
features a supported frequency range from 4 Hz to 10 MHz
across two models. The R&S LCX100 covers a frequency range
from 4 Hz to 300 kHz, the R&S LCX200 a basic frequency
range from 4 Hz to 500 kHz with options to cover all frequencies
up to 10 MHz. The auto-balancing bridge technology
used by the LCX supports conventional impedance measurements
by measuring the AC voltage and current for the device
under test, including the phase shift. This is then used to
calculate complex impedance at any given operational point.

Common-mode filters
TDK (Tokyo, Japan) developed the
KCZ1210DH series common-mode
filters for automotive applications.
This series provides a noise control
function for high-speed differential
transmission signal lines for automobiles.
TDK states that the product supports high-speed signals
with over 10 Gbps transmission rates. Additionally, it contributes
to noise control in the GHz band generated due to
increased speed. TDK also states that by supporting an operating
temperature range from -55 to 125 Celsius (-67 to 257
Fahrenheit) and adopting a conductive resin-based electrode
mitigated cracks from thermal shock while increasing durability
against mechanical stresses like substrate strains. The outer
dimensions are 1.25 (L) x 1.0 (W) x 0.5 mm (H)
(.049x.039x.19-inches), which saves board mounting space.

Water-based emulsifier
Solvay (Brussels, Belgium) has developed
Reactsurf 0092, an alkylphenol ethoxylatesfree
and non-ionic reactive water-based emulsifier
for solid epoxy resins. The intended use
for this emulsifier is industrial coatings and
paints or binders. Solvay claims this emulsifier
can match or exceed the performance of solvent-based
coatings but with an appreciably
lower level of VOCs. Solvay also states that
waterborne epoxy emulsions that incorporate
Reactsurf 0092 are still flowable under -10°C (+14°F) at up to
5 F/T cycles. Results of salt-spray tests (ASTM B-117) on cold
steel rolled plates coated with epoxy emulsion paint reportedly
displayed a combination of high corrosion resistance,
superior wet-adhesion and no peel-off.

Hall-effect sensor
Allegro MicroSystems (Manchester,
New Hampshire) announced its new
A33230 3D sine/cosine hall-effect
position sensor. According to Allegro,
the A33230 is the smallest 3D sine/
cosine sensor currently available. The
sensor contains two discrete analog signal paths for highspeed
performance and can also be used as an angle sensing
device, provided the system includes an electronic control unit
(ECU) capable of performing CORDIC calculations on the two
outputs. The A33230 also incorporates vertical and planar Halleffect
elements with sensing axes that are orthogonal to one
another and is pre-programmed to measure angle in any plane
while providing independent sine and cosine outputs.
