Filtered Circular Connectors

Compact and Extended Shell Filtered Connectors Manufactured in the EU

API’s line of custom filtered connector offerings are fully vertically integrated. Components including capacitors and shells are manufactured by API, providing our customers high quality parts at very competitive prices, with the industry’s shortest lead times.

Our compact shell filtered connectors offer designers an effective filtering device that reduces the amount of real estate required within a product enclosure. Our extended shell connectors are constructed by adding either planar or tubular capacitor filtering to the rear of a standard connector, which makes them ideal when quick turnaround is required for prototype devices.

Overview
  • Multi-layer thick-film hybrid interconnect
  • Material systems include gold for wire bonding and blends of silver and gold with platinum and palladium for solder based assemblies.
  • Conventional screen printing is supplemented by a photo-defined process to achieve high-density, high-precision conductors (25um width).
  • Diffusion Patterning is also employed to provide small diameter, high density vias in dielectric layers.
  • This photoetchable technology can be combined with standard thick-film processing to provide complex, high-density multi-layer substrates suitable for RF and microwave applications.
Highlights
  • For the ultimate performance and reliability, hybrid packages are hermetically sealed in dry nitrogen and low out-gassing adhesives
  • Eutectic bonds are used throughout to maintain high performance over long operating life times.
  • Both gold and aluminium wire bonding completes the circuit interconnect and package connections.
  • Reliability is assured via established design rules, careful element (component) evaluation, 100% environmental screening and extensive process control and product qualification procedures.

Quality Acceptance Test Specifications


Quality Acceptance Test Specifications

All filtered connectors undergo extensive testing to assure that all product meets our high quality expectations and meet your standards. Many of the tests are performed 100% as routine and others are carried out on a sample basis when this is deemed more meaningful.

Visual

The connectors shall be manufactured and processed in a careful and workmanlike manner in accordance with good design and sound practice.

Capacitance

Capacitance is checked on 100% of the contacts per detailed specifications when measured at 25°C, 1 KHz, 0.1 to 1.0VRMS. On insulated feed-thru lines, the maximum capacitance is 25 pF.

Dissipation factor

4% maximum, checked 100% at 25°C, 1KHz, 0.1 to 1.0VRMS

Dielectric withstanding voltage

Performed on 100% of the filtered contacts, the test voltage, unless otherwise specified, will be 2.5 times the working voltage as specified at 25°C. This voltage will be applied for 1 to 5 seconds with the charging current limited to 50 milliamps.

Insulation resistance

Performed on 100% of the filtered contacts at 25°C, the minimum acceptance level will be 1000 megohms at 25°C and 100 megohms at 125°C if required. This test will be carried out in accordance with MIL-STD-202 Method 302, test voltage of 100VDC or at rated voltage whichever is less.

Insertion loss

Performed on a sample quantity of filtered contacts, minimum acceptance levels as specified by typical insertion loss graphs.

DC Resistance

The DCR on ground lines is 5 milliohms max.

Marking

As a minimum, all connectors shall have the API Technologies part number & date code. Upon request, customer specified marking can be incorporated into the manufacturing cycle.
