Syfer, Novacap, DLI and Voltronics now -Knowles Capacitors-

On March 3rd 2014 Dover completed the spin off of Knowles Corporation. During this transition, the former CMP Group was fully transferred to the new organization.

The created Knowles Corporation exists of the brands Knowles, Sound Solutions, Vectron, DLI, Novacap, Syfer and Voltronics.

Knowles Corporation is a market leader and global supplier of advanced micro-acoustic solutions and specialty components serving the mobile communications, consumer electronics, medical, military, aerospace and industrial markets.

The company is organized in 2 segments:

* Mobile Consumer Electronics: Provides the acoustic backbone to smartphones, tablets, headsets, laptops and other electronic products

* Specialty Components: Includes acoustic solutions for hearing aids, and oscillators and capacitors used in a broad range of electronic equipment

 

Knowles Capacitors

Knowles Capacitors, as one of the divisions of Knowles Corporation, is one company with 5 Product Groups and 4 Brands. This means that the different manufacturers under the CMP Group (Syfer Technology, Novacap, DLI and Voltronics) don't exist any longer. They've turned into one company with different brands. This one company has one business approach with one sales team creating one face to the customers.

 
The 5 Product Groups are

MLC Product Line
* High volume X7R, C0G
* Telecom & MRI Hi-Q

* Surface mount EMI filters

* Standardize production
* New PSL series – with standard P/Ns for power supply, LED and other high volume applications
* New Ultra Low ESR Hi-Q Range
 
Hi-Rel Product Line
* High reliability, medical, military
* Hi-Temp
* Military Hi-Q
* Leaded, stacked chips
* Planar arrays
* Feedthrough filters
* Non-standard parts & assemblies
 
SLC Product Line
* Single layer capacitors
* Hi-rel parts for military and space
* Heat sinks
* New product introductions for Telecom and Military customers
   - High cap SLC
   - 50V rated SLC
 
Thin Film Product Line
* Thin film devices
* Thin Film filters for military
 
Trimmer Capacitor Product Line
* Precisions multi-turn trimmers, ½ turn trimmers
* Strong product range for MRI applications
* New products

  • Aluminum Electrolytic Capacitors vs. Film Capacitors

    The progress in semiconductor design sets the trend in current and future devices of power electronics: it manifests itself particularly in smaller dimensions, as well as in higher voltages and switching frequencies. Referring to intermediate circuit capacitors, this trend leads to aiming at higher energy densities and larger current loads, and – at the same time – decreasing space.

    Under these conditions, especially aluminum electrolytic capacitors and plastic film capacitors offer advantageous solutions. Jianghai has both technologies in the production program and this article gives an overview on the major differences between aluminum electrolytic capacitors and film capacitors.

  • Prudent use of electrolytic capacitors in vibrating applications

    The use of electrolytic capacitors in vibrating applications like motor controllers or power tools, must be considered very carefully regarding specific criteria.
    When you're designing electronic control applications or drives, you have to think about specifications like higher power and miniaturisation.
    If you're designing vibrating applications however, you should not forget to think about vibration resistance and temperature!

  • Miniaturization of HV applications: a solution for every Power Electronics Engineer

    StackiCap™ has been set to revolutionise the world of large, HV(200V – 2kV), X7R Multilayer Chip Capacitors (MLCCs)!

    It dramatically increases the max capacitance values within a size/voltage or can reduce chip sizes. They take up 1/10th of the current footprint dimension and save up to 9/10th of the weight of a stacked cap. The advantages are spectacular on any HV products where pcb space is at a premium and max. capacitance is required in a smaller footprint. Typical applications include power supplies, projector modules, lighting systems and throughout the aerospace sector.

  • High Voltage SM Capacitors

    Is High Voltage in relatively small case sizes a great issue for you?  ProtectiCap™ of Syfer will open a lot of oppertunities. The integral coating of this capacitor series minimizes the risk of flashover from one termination of the chip to the other, without any requirement for the customer to apply conformal coating after soldering.
