Do you know what passive devices are? While engineers and designers within your organization know, procurement personnel may not be up to speed with passive devices. If you’ve involved with e-procurement or supply chain processes and your curiosity about passive electronic components is anything but passive, you’ve come to the right place!

At Sourcengine, we empower purchasing departments and procurement specialists every day. And we think a little extra knowledge about those items on a Bill of Material (BOM) or invoice benefits everyone.

Passive vs. Active: Understanding Electronic Component Functionality

Most electronic devices and parts are distinguished by how they interact with electricity. In this regard, there are two main types:

  • Active components. Active electronic devices are able to manipulate electricity, plain and simple. Think of diodes (essentially, one-way electricity conduits) and LEDs as active electronic components. Transistors are another great example of an active device. If electric current is somehow changed with a device – amplified, restricted, turned on/off, etc. – it’s “active."

  • Passive components. Unlike active devices, passive electronic components do not have the ability to actually control electric current. Resistors, capacitors, sensors, antennas, resonators, and similar devices are passive electronic parts. Diodes can be considered passive, depending on their particular function. Diodes are one of the few electronic devices that are both active or passive.

So why is this distinction so important? All electronic devices must contain at least one active component. A printed circuit board (PCB) is a great example of an electronic device. Without LEDs or transistors, the entire assembly would be considered passive in nature.

Every finished electronic device has a combination of active and passive components. Both are essential, whether the product is the newest iPhone or a complex IoT subsystem for connected automobiles.
