Operating Temperature Range is -40 Degrees C to +125 Degrees C,
Corresponding to the Severe Environment within an Engine
Compartment TDK Corporation (NYSE:TDK) has announced the
development and commercialization of the ACM90V-701-2PL common-mode
filter designed for in-vehicle power line conditioning. The
dimensions of this power line noise suppression SMD device are
9.0mm (L) x 7.0mm (W) x 4.3mm (T). Its operating temperature range
is -40 degrees C to +125 degrees C, exceeding TDK's previous
component operating temperature range of -25 degrees C to +85
degrees C. In the automotive field electronic control technology is
rapidly advancing and the percentage of ECU-equipped vehicles is
increasing. In particular, the rapid increase in ECU's installed in
severe temperature environments, such as the engine compartment,
are increasing the requirements of noise suppression component
capabilities. In this case, noise suppression components with high
temperature resistance and high reliability are highly desirable.
In response to these market demands, this product incorporates high
temperature resistant insulation-coated wire and product
construction emphasizing shock and vibration resistance.
Specifically, this product achieves an operating temperature range
of -40 degrees C to +125 degrees C. The reliability that these
features provide make this common-mode filter ideally suited for
in-vehicle ECU power line conditioning. As of April 4, 2006
according to TDK investigation. Explanation of Terminology ECU:
Electronic Control Unit. Originally the primary purpose of an
in-vehicle ECU was engine control. However, recently ECU's have
been used to control a variety of drive system functions including
ABS and EPS. Major Applications Noise suppression for the power
supply lines of ECU, vehicle navigation, and other devices Major
Features 1. Operating temperature range -40 degrees C to +125
degrees C 2. Reliability assurance testing Thermal shock test
between -40 degrees C and +125 degrees C, with 30 minute hold
times, for 1000 cycles. 3. Lead free This product contains no lead
or lead compounds, and can be mounted using lead-free processes.
