Technology Update

With the increasing demand for lighter weight and more

rugged filter connectors, ITT Electronic Components, has

advanced the state of the art in filter technology with the

new Cannon Chip-on-Flex (CoF) design.

Cannon’s Chip-on-Flex filter connector technology

provides a significant performance improvement in

thermal shock and vibration to the ceramic planar array

technology that is the current industry standard. The

current planar array design utilizes a ceramic block

capacitor with plated thru holes where feed thru contacts

are inserted and soldered into place. Internal stresses

associated with vibration, thermal expansion/contraction

can build at the solder joints and

Solder Joint

cause the ceramic material to crack

resulting in a filter failure. As a

consequence, costly thermal shock

screening and burn in procedures

are often used for quality

assurance.

Ceramic

Array

Rugged Design plus up to

15% Savings in Weight

Cannon’s new Chip-on-Flex filter connector has the additional

benefit of being the lightest weight design. The 38999-Style

Series III CoF offers up to a 15% savings in weight over the

ceramic planar array equivalent.

The new Chip-on-Flex connector

will protect critical circuits from

electrical interference providing

a “stray signal barrier”

upstream and away from

electronic devices without

affecting system function and

performance.

The Chip-on-Flex filter

connector provides all the

same benefits of filter

connector technologies.

New Chip-on-Flex Design

In the new Cannon Chip-on-Flex

design, the internal thermal shock

stresses have been virtually

38999-Style

eliminated. The fragile

Current Planar Array Design

ceramic planar array

capacitor block has been

replaced by a flex circuit where individual chip capacitors

are surface mounted on a pad adjacent to the feed thru

contact.

The result is a very robust filter connector with superior

mechanical performance and improved reliability.

1. Individual isolated pin filtering of high frequency

noise, shunted to ground via the connector shell.

The cut-in frequency of the filtering is selected by

the user from the performance attenuation curves.

2. Built-in ground plane barrier in the connector insert.

This eliminates EMI windows on the face of systems

where connectors enter or exit boxes.

3. Filtering at the face of system boxes eliminating

filtering on the PCB, freeing up board space, and

maintaining EMI integrity of the system by not

allowing unwanted signals to enter the box.

New Design/Development Flexibility and

Reduced Leadtimes

Cannon’s Chip-on-Flex filter design offers the system

designer new and complete flexibility in defining or

changing individual circuit requirements without the need

to retool the ceramic planar array. The Chip-on-Flex

design utilizes readily available flex circuits and devices

leading to reduced design / development cycle time and

overall production delivery.

1. Virtually no limitations on the variation in

capacitance/feed-thru/ground/diode choices that is

readily available to the customer. The exact same

flex circuit is used. Cannon installs the appropriate

device in each location as selected by the customer.

2. EMP protection can be simply added by substituting

a Zener diode in place of a chip capacitor.

The CoF filter connectors are ideal for high reliability military,

aerospace and industrial applications:

Test Description

Insulation Resistance

Paragraph

Requirements

Insulation resistance test is performed on unmated connectors per MIL-STD-1344, method 3003. The test

voltage is 100 Vdc minimum. Standard quality conformance testing is done, where all contacts are measured

to all other contacts and the shell at room temperature. The minimum requirement is 5,000 Megohms at room

temperature and 1,000 Megohms at 125

Dielectric Withstanding Voltage (DWV) is performed on unmated connectors per MIL-STD-1344, method 3001.

Standard quality conformance testing is done, where all contacts are measured to all other contacts and the

shell at room temperature. Leakage current shall not exceed 100 microamps at the shown minimum test
