Before revision: Integrated Passive Devices (IPD's) " or Integrated Passive Components (IPC's) or Embedded Passive Components " are electronic components where resistors (R), capacitors (C), inductors (L)/coils/chokes, microstriplines, impedance matching elements, baluns or any combinations of them are integrated in the same package or on the same substrate.
After revision: Integrated Passive Devices (IPD's) or Integrated Passive Components (IPC's) or Embedded Passive Components are electronic components where resistors (R), capacitors (C), inductors (L)/coils/chokes, microstriplines, impedance matching elements, baluns or any combinations of them are integrated in the same package or on the same substrate.
