From Mr. Google : "Rare earth elements (REEs) aren't a capacitor type but are crucial additives. Oxides of elements like neodymium (Nd) and samarium (Sm) improve stability, temperature performance, and reduce drift, making them vital for precise timing, filtering, and decoupling in electronics. These REEs enhance dielectric properties in functional ceramics, improving overall component reliability, though they are used in small amounts."
