FAQ
Q: What is micro2 blade fuse for automotive?
A: Micro2 blade fuse for automotive is subminiature ATR type two-pin car blade fuse, smaller than standard mini fuse, designed for compact fuse boxes in new generation vehicles.
Q: What voltage is Micro2 automotive fuse rated?
A: Rated 32V DC, only for automotive direct current circuits, not suitable for AC power supply.
Q: What amp ratings are available for Micro2 blade fuse?
A: 5A,7.5A,10A,15A,20A,25A,30A, color coded for quick recognition.
Q: What is the difference between tin-plated and silver-plated terminals?
A: Silver-plated version supports higher max working temperature up to 125°C, recommended for engine compartment high-temperature installation; tin-plated for cabin interior circuits.
Q: Do Micro2 fuses need temperature derating?
A: Yes. Continuous current must be derated when installed in high-temperature environments to avoid premature blowing.
Q: Are these Micro2 blade fuses RoHS compliant?
A: Yes, all micro2 blade fuses are RoHS and lead-free, meet export requirements for global automotive markets.
Q: Can we get bulk wholesale and OEM service?
A: Yes, we provide bulk supply, custom packaging and OEM marking service. Contact our sales team for datasheet and quotation.
