The market requires tough products. So we have already extended
the temperature range of Q+products ferrite sleeves to -55 °C /
+150 °C. We also aim to extend such increases in temperature range
to include all Q+products.
Temperature range up to +150 °C

Standards by Comparison
Although it might seem much better at the first sight, it doesn’t mean, that the industrial parts are less qualified than the Q+ Products. The
difference in here is the higher reliable requirements which we going to prove accordance to the AEC-Q 200. To show the difference, the
following table contrasts some main parts out of the industrial qualification standard of Würth Elektronik eiSos with the main necessary
qualification standards out of the AEC-Q 200.

WE-CBA
SMD EMI Suppression Ferrite Bead
Size 0402
Characteristics
Applications
Reliable Ni-Sn electrodes
High rated current up to 5 A
Recommended soldering: Reflow
Operating temperature: -55 °C to +125 °C
Perfect as data lined filter and for uncoupling
of distribution voltage
Type definition of SMD ferrites WE-CBA
Derating +85 °C
The special SMD chip bead ferrites can be put directly on the printed circuit board. They offer excellent anti-EMI properties and low
DC-resistance. Placed very close next to the interference source even with smallest size 0402, maximal impedance at 1000 Ω can
be reached.
High Speed:
“High Speed” SMD ferrites WE-CBA have lower impedance in the lower frequency ranges thus they have only a low attenuation
for fast signals.
Application e.g. USB 2.0, IEEE 1394, LVDS
Wide Band:
“Wide Band” SMD ferrites WE-CBA already show high impedance in low frequency range. Therefore they are wide band through
the whole spectrum.
Application e.g. control signals, RS232, RS422, DC/DC converter
Derating +105 °C
High Current:
“High Current” SMD ferrites WE-CBA are designed for high current (over 1 A). The rated current refers to 40 K self-heating.
High current SMD ferrites are available in all three types (High Speed, Wide Band and High Frequency).
Application e.g. power supply, DC/DC converter
Advice: Pay attention for the use of SMD ferrites for high rated current >1 A and ambient temperature over +85 °C that the rated
current has to be reduced when temperature is above +85 °C (Derating).
The characteristic line in the right figure shows, that e.g. at +100 °C ambient temperature the maximal rated current has to add
up to only 60 % of the data sheet value, without an overload of the component.

WE-PD2A
SMD Power Inductor
Size 4532
Characteristics
Applications
Open size
Current capability up to 14 A
Operating temperature: -40 °C to +125 °C
Recommended solder profile: Reflow
Switching regulators with low operating voltage
(navigation system, air conditioning, entertainment,
park assistance control)
Integrated DC/DC-converter
Perfectly suitable for switching regulators with
extremely high efficiency
Note
The ambient temperature when operating the WE-PD series of storage chokes at full current rating load should generally range from
-40 °C to +85 °C. The self-heating of the component must be taken into account at higher ambient temperatures in order that the
permissible solder joint temperature is not exceeded or the wire insulation damaged. The wire used can withstand a temperature of
up to +150 °C. The ferrite core itself may be used over a far greater temperature range (approx. -50 °C to +250 °C [Curie temperature]). However, in this case, the tolerance limits of the inductor may be exceeded due to the temperature dependence of permeability.

General:
All recommendations according to the general technical specifications of the datasheet have to be complied with.
The disposal and operation of the product within ambient conditions which probably alloy or harm the component surface
has to be avoided.
If the product is potted in costumer applications, the potting material might shrink during and after hardening. Accordingly to this the product is exposed to the pressure of the potting material with the effect that the ferrite body and termination
is possibly damaged by this pressure and so the electrical as well as the mechanical characteristics are endanger to be
affected. After the potting material is cured, the ferrite body and termination of the product have to be checked if any
reduced electrical or mechanical functions or destructions have occurred.
The responsibility for the applicability of customer specific products and use in a particular customer design is always
within the authority of the customer. All technical specifications for standard products do also apply for customer specific
products.
Washing varnish agent that is used during the production to clean the application might damage or change the characteristics of the plating. The washing varnish agent could have a negative effect on the long term function of the product.
Direct mechanical impact to the product shall be prevented as the ferrite material of the ferrite body could flake or in the
worst case it could break.
Product specific:
Follow all instructions mentioned in the datasheet, especially:
The solder profile has to be complied with according to the technical reflow soldering specification,
otherwise no warranty will be sustained.
Wave soldering is only allowed after evaluation and approval.
All products are supposed to be used before the end of the period of 12 months based on the
product date-code, if not a 100 % solderability can’t be warranted.
Violation of the technical product specifications such as exceeding the nominal rated current
will result in the loss of warranty.
Information in this catalogue is subject to change. The process of continually improving our product range leads to changes
in content. For new designs please refer to our latest data sheets on www.we-online.com or contact our field staff.
