New processes cut capacitor thickness
Developments in the 'wet process' used to screen print the di-electric material have allowed Syfer to produce thinner layers.
Low fire ceramic chip fabrication technology has enabled Syfer Technology, to launch its highest capacitance devices ever Increased capacitance versions of its 16, 25 and 50/63V series of multilayer chip capacitors have been released, along with new versions built on an X5R di-electric and a 10V range

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.
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.
Developments in the 'wet process' used to screen print the di-electric material have allowed the company to produce thinner layers.
This results in a significant increase in the maximum feasible capacitance possible for a given voltage.
It has enabled Syfer to introduce a lower voltage, 10V range for the first time.
Capacitance has more than doubled in most devices in Syfer's standard multilayer chip capacitor ranges based on the C0G di-electric.
A new 10V range is available on the C0G di-electric, with devices ranging from a 0603 device with 3.9nF capacitance to a 560nF part in a 2225 footprint.
Syfer has also introduced an X5R di-electric, in voltages from 10 to 53/65V and packages from 0603 to 2225, typically providing greater capacitance than their X7R counterparts.
A typical device, such as the 0805 footprint 10V part, now features 680nF capacitance, more than double the 330nF available previously.
However, these X5R parts are only specified to 85C, while the X7R range is qualified up to 125C.
Low fire capacitors offer greater reliability than those produced using a high fire process.
For medical, automotive, military and aerospace and industrial control, ruggedness and reliability are critical.
Typically the low fire process produces a more structurally stable component body, with a higher di-electric constant, a lower volt per micron rating and reduced capacitance loss.
For added reliability, Syfer offers its Flexicap polymer termination option as an alternative to a standard plated termination.
Flexicap accommodates a greater degree of board flex than a conventional termination.
To meet the most stringent quality standards, Syfer offers additional testing services.
The new parts, manufactured at Syfer's Norwich, UK facility, are already available in production volumes, on standard five-week delivery times.
RoHS-compliant versions are available.
