※FM5 is indentifying symbol of terminal specification.
※Please feel free to contact us in regard of M4 terminal.

※1 This is maximum voltage value at which BZ07 can open a circuit under rated current condition. (Please note it is different from voltage value that can be applied to resistor part.)Please use BZ07 in accordance with the derating curve, if voltage exceeds 60V.
※Please us BZ07 in accordance with the derating curve, if ambient temperature exceeds 70℃.
※Resistance value can be changed 4.7Ω~160Ω(±5%) as new type. UL1412 contains no provisions concerning rated current, so above-mentioned is our own specification.
