Is it good for tantalum capacitors to filter high frequencies?

I use it for the decoupling of the 433MHZ RF circuit, and I want to filter the high frequency part with a tantalum capacitor. Originally wanted to use monolithic capacitors or ceramic capacitors. But there are no SMD monolithic or ceramic capacitors.

Hard to know without advice from someone whos either an electrical engineer or has tested capacitors with your specific speed controller. Do you own an oscilloscope by any chance?
