Can you help me identify these two components? I cannot find information on them on the web. They appear to be ceramic filters of some kind.

    \$\begingroup\$ these cannot be filters, because they'd need a third/ground pin to dump rejected energy into. \$\endgroup\$ – analogsystemsrf Jul 2 at 2:05

They are resettable fuses, the big one is 600V for 160mA

The second is 30V for 1.6A
