X2Y Construction (2)

• Each electrode is shielded by 2 ground
  electrodes.
• All ground electrodes connected to both
  side-terminations
• sizes as normal MLCCs (0603, 0805, .)
• ceramics as normal MLCCs (NP0, X7R, ..)

X2Y Benefits (1)

• Broadband Filter and Decoupler X2Y is effective
  upto 10 GHz and frequencies beyond
• By-pass Unlike feedthrough capacitors, X2Y
  devices are in by-pass and only handle the noise
  current.
• Superior Balance 2 internally balanced Y-caps
  help to maintain balance over time (aging) and
  temperature.
• Ultra-low Inductance typical equivalent series
  inductance (ESL) to less than 50 picohenries.

7
X2Y Benefits (2)

• Ultra-low ESR typical values of a few
  milli-ohms.
• Lower Component and Placement Costs X2Y
  eliminates inductors, ferrites, standard caps,
  resistors and varistors normally combined to form
  filter networks in the past.
• Board Space Reduced On the PCB board, X2Y
  components allow for design simplification
  resulting in a substantial reduction of board
  space needed.

New EMC rules on automotive

• Laws / standards which demand reduced emission
  from electronics are in place and shifting from
  usage on voluntary base to mandatory use (e.g.
  CISPR 25 level 5).
• Industries which have to plan ahead longtime,
  e.g. automotive, recognize this and are working
  on solutions to meet new requirements
• OEMs like Delphi (for GM), FCI (for Chrysler),
  Visteon (for Ford), Valeo and Molex are
  evaluating or have evaluated the possibilities of
  this technology

Advantages of using X2Y in DC Motor

• Improved performance
• Better noise reduction in a larger frequency
  range
• Meeting new automotive EMC rules
• Cost reduction
• Replacement of expensive components like chokes,
  capacitors, varistors. Up to 7 components can be
  replaced by one X2Y product.
• Less board space needed
• Lower placement costs
• Shorter design time

Benefits of filtering with X2Y balanced filters
in connectors

• Best EMI filtering achievable. New standards on
  emission (radiation) can be met
• Filtering of high speed data signal lines. Two
  data lines can be filtered simultaneously with
  one X2Y filter.
• Improved ESD performance
• Filtering of both common- and differential mode
  noise
• simultaneously with one X2Y-capacitor.

Airbag connector (ABX-3)
Background
Throughout the industry, airbag connector
manufacturers have long utilized ferromagnetic
devices to suppress EMI/RFI phenomenon in an
airbag safety restraint system. Other solutions,
such as coiled wire soldered into place (within
the connector), proved to be more expensive and
suffered from sizing constraints. Airbag
connectors have long been plagued with these and
other problems directly involving these
components. These other problems range from poor
EMI suppression characteristics to cracking and
breaking of the suppression components in
assembly processes. To solve these problems, a
device that has superior EMI suppression
capabilities, coupled with excellent robustness,
has been designed for introduction into the
airbag safety restraint system.

Current Circuit Configuration (Ferrites)
Potential failure modes include chipping and
cracking of ferrite material and phase angle, Rs,
and/or impedance failures.

EMI Suppression - Alternative Device
The Insert Concept
This concept is based on existing connector to
connector EMI gaskets/filters currently used in
many consumer and military applications. This
concept proved to be the most effective choice
offering little change to FCI products. It
utilizes Surface Mount Technology (SMT) and
state-of-the-art filtering component design.

  X2Y solves all EMI problems. It is the only
  proven concept that meets the EMC requirements
• X2Y saves you money replacement of many
