enter image description hereGot curious about these components because they seem very different from what I've used till now.

  • \$\begingroup\$ Someone appears to have removed identifying markings from the green components? They're probably capacitors. The orange ones are definitely capacitors. The white "TIC 0E1" look like power resistors. \$\endgroup\$ – pjc50 Mar 13 '17 at 11:24
  • \$\begingroup\$ Can you read any of the values of the green components or even get a picture of where it's scratched off? They're probably capacitors but other components do come in that package type. \$\endgroup\$ – Doodle Mar 13 '17 at 11:28
  • \$\begingroup\$ They are totally scratched, not readable. \$\endgroup\$ – user134265 Mar 13 '17 at 11:41

The white components are ceramic power resistors. They are rated at 5W and have a resistance of 0.1 Ohms. They're sometimes used as current shunts in lower power applications.

The green components are most likely capacitors, usually in this package they're known as film capacitors. As pjc50 mentions, the values seem to be scratched off (odd thing to do to a capacitor). This suggests they might not be a capacitor, RC snubbers also come in this package type as well as other components.

The orange components are without doubt capacitors.

    \$\begingroup\$ These green components are on the PCB of an therapeutic ultrasound generator. May be they didn't wish other people to repair it. \$\endgroup\$ – user134265 Mar 13 '17 at 11:41
  • \$\begingroup\$ @user134265 It's not like you can desolder it and measure the capacitance... oh wait.... \$\endgroup\$ – immibis Jan 24 '18 at 0:36
