Three capacitors in one for suppression
The X2Y is an integrated passive component, providing three capacitors in one device, thereby dramatically reducing the total number of standard passive components required.
With the twin advantages of reduced component count and high mechanical integrity, UK-based component manufacturer Syfer Technology has released an extended range of RoHS-compliant X2Y three terminal capacitors Aimed at decoupling and EMI suppression tasks in a variety of general purpose and function specific applications, Syfer's X2Y range is ideal for designs where space is at a premium

The latest designs of surface mount chip capacitors available from leading UK passive component manufacturer Syfer Technology can now be supplied with traditional tin/lead terminations.
Radial lead capacitors are RoHS compliant
All standard ranges of radial lead capacitors are now available with tin terminations, in place of the traditional tin-lead terminations on the leads.
The X2Y is an integrated passive component, providing three capacitors in one device, thereby dramatically reducing the total number of standard passive components required.
A reduced component count can lead to significant cost savings, reduced assembly time and higher product reliability.
In addition, these X2Y capacitors are optionally available with Syfer's innovative flexible terminations, called FlexiCap.

T-filters provide EMI protection
Syfer Technology has brought out a new range of compact, panel-mounted T filters to provide EMI protection in a wide range of industry sectors.
Radial-lead capacitors answer HV demands
High-voltage radial-lead capacitors extend to 5kV, and custom designs for specialist applications up to 10kV can be supplied.
This technology, unique to Syfer, is designed to reduce the risk of mechanical damage, such as cracking, during handling and assembly processes.
FlexiCap is applied to the termination areas underneath the nickel barrier coating and tin-plated finish.
The inherent flexibility of the material provides greater scope for the device to accommodate the mechanical stresses typically present in PCB assembly operations, and also in the field, particularly for portable products.
One of the most important features of X2Y dielectric technology is that it exhibits extremely low self-inductance, making it particularly suitable for high frequency decoupling applications.
With the rapid growth in high speed communications and multimedia technology, particularly for broadband circuits, these devices are in increasing demand for both decoupling and suppression.
Syfer's range of balanced line, three terminal X2Y chips provide simultaneous line to line and line to ground filtering.
Delivering both differential and common mode filtering, in a compact package, they are ideal for balanced line, EMI suppression in DC motors in a wide range of automotive, telecomms and industrial applications.
The filter devices are well suited for use in sensors (including Hall effect), filtered connectors and fibre optic components, crystal circuits and LED modules.
Syfer's X2Y filter capacitors are ideal for CANbus applications, as well as for audio amplifiers and micropower instrumentation amplifiers.
There is growing interest from customers in the military and medical sectors; and the devices can also be used in general signal line filtering applications, particularly in multiple-PCB based systems and to provide bulk capacitance for switching power supplies.
The chips are available in various combinations of capacitance values, from 10pF up to 1.2uF, with rated voltages of 25, 50 or 100V, in case sizes from 0603 to 2220.
Syfer's balanced line X2Y and three-terminal chip ranges are fully RoHS compliant, and already in volume production at its upgraded, state-of-the-art, Norwich, Norfolk, UK facility.
The devices are currently on a 6-week lead time, and any quantity of devices can be ordered from samples through to high volume, for delivery loose, or taped and reeled for automated assembly systems.
Pricing depends on chip size and quantity, but in general range from GBP 0.03 to GBP 0.40 each.
Syfer has invested heavily in developing RoHS compliant devices across its entire product range.
Its expanding range of RoHS compliant EMI filters includes three-terminal EMI chips, high current EMI chips, X2Y balanced line chips and 1206 size pi-filters.
