1) Ana iya lura cewa maye gurbin TDK na Murata shine kawai maye gurbin. Misali, Murata's DHS4E4C532KT2B 15KV 5300PF N4700 ya dace da TDK tare da madaidaicin madaidaicin 15KV 7000PF, Y5S. Mun san cewa duk da cewa kayan Y5S na TDK yana nuna ƙarancin ƙarancin ƙarancin aiki, ainihin ma'auni yana nuna ƙima mai kama da matakin N4700. Koyaya, tukwane na Class 2 kamar Y5S ba su iya yin aiki haka kuma yumbu na Class 1 a cikin mahalli masu girma. Bugu da ƙari, ƙarfin 7000PF daga TDK na iya zama babba ga abokan cinikin da suka saba yin amfani da capacitors na Murata, kuma girman ɓangaren ƙila ba zai yi daidai da ainihin samfuran Murata ba.
