How to choose filter connector

Cut-off frequency is the key point for choosing filter connectors except the common point when choosing normal electric connectors; it shall be confirmed by the highest frequency when contact signal frequency is different. Below are the points for choosing the right filter connector

filter connector

1.       Filter index calculation

Decrement for filter control transmission can be calculated by comparing transmitted spectrum and EMC standards; immunity control can be calculated by comparing external electrical noise and sensibility of electronic circuit.

2.       Impedance and power-line filter

Filter is composed by inductance and capacitor and it is a resonance circuit, connector performance and resonance depends on impedance of source side and load end.

Connectors for embedded computer market

The connector market for embedded computing is forecast to reach $168.5 million in 2013, up 4.2 percent year over year from 2012, miniaturization, low power, high performance, innovative design and harsh environment application, etc. has become embedded computer trends. The commodity PC can not satisfy the requirements of many industries, not matter stability, reliability, expansibility or environment adaptability.

In order to meet the requirement of embedded computer market trend, connector design shall be modified, such as lower mating forces, smaller contact centerlines, increased power rating, higher temperature rating, sealed standard, impedance control, PCB launch, new contact designs and plating.
