Comms chip can halve board space
01 September 2006
A resistor capacitor network that can replace up to 16 discrete components and take up 50 per cent of the conventional board space required has been developed by BI Technologies (www.bitechnology.co.uk)
SMT division, based in Glenrothes, Scotland.
The RC series of thick film on ceramic chip networks can replace up to 16 discrete components, saving component count as well as board space, assembly costs and also the number of solder joints and traces on the PCB, which improves overall reliability.
The networks are also not susceptible, according to the company, to electrostatic discharge and do not require diode protection. In this way, they can be placed near active devices to reduce routing and to minimise the inductance from long traces on the circuit boards.
They can be used for line terminations and EMI, keypad, ECG input, parallel and serial port as well as SCART port, keyboard and mouse and control and data line filters in laptops and notebooks, workstations, in multimedia, automotive applications, including set top boxes and mobile phones and computer peripherals.
The devices are avaialble in 1206 packages and in five circuit configurations in a 10-terminal 2512 array.
Power ratings are 63mW/resistor with resistance ranging from 20Ù to 1MÙ with standard tolerance of ±20 per cent. Capacitor dielectric is X7R with a tolerance of ±20 per cent.
