How much current can a ribbon cable take?
The current limit for a single connection is as great as 4.5 amps, but if all lines carry equal current, the capability drops to a 1.5A limit. Fig. 2 This 3M™ 891 Series AWG26 IDC ribbon cable connector handles 1.5A per line.
Why is ribbon cable used?
Ribbon cabling is used for data transmission and communications. It is often chosen for computer cable applications, where it is used as internal wiring for hard drives, CD drives, and more. Ribbon cables are also commonly used as internal wiring for other electronics and appliances.
What devices have a ribbon cable?
Ribbon cables are usually seen for internal peripherals in computers, such as hard drives, CD drives and floppy drives. On some older computer systems (such as the BBC Micro and Apple II series) they were used for external connections as well.
How do you protect ribbon cables?
How to shield multiple flat (ribbon) cables properly?
- Putting aluminum tape around cables and grounding it on metal case.
- Separating and twisting flat cables as much as possible (tho that would look ugly and messy so I would like to avoid that)
- Distancing them with one from another with aluminum tape and foam tape.
Which is the biggest generator of wide band noise?
In high-speed digital circuits, the clock circuitry is usually the biggest generator of wide-band noise. In faster MCUs, these circuits can produce harmonic distortions up to 300 MHz, which should be eliminated. In digital circuits, the most vulnerable elements are the reset lines, interrupt lines, and control lines.
How to calculate the radiated susceptibility of a circuit?
Radiated Susceptibility a.Modelling a two conductor line to determine the terminal voltages induced by incident eletromagnetic field. 8-2 Simple Susceptibility Models for wires and PCB Lands
How can I reduce HF noise in my microcontroller?
Series inductors or ferrite beads will reduce the amount of HF noise that reaches the microcontroller pin. They will have high impedance for HF, while having low impedance for low-frequency signals. Decoupling capacitors on the input lines will short the HF noise to ground.
