Frequently Asked Questions
Q: What is the difference between 1206 and 0603 SMD fuse package sizes?
A: The numbers refer to the physical dimensions of the surface-mount component. A 1206 fuse measures approximately 3.2mm × 1.6mm, while a 0603 fuse measures approximately 1.6mm × 0.8mm. The 0603 package is smaller and suited for more compact PCB layouts, while the 1206 is easier to hand-solder and handle during prototyping. Both are included in this assortment for maximum flexibility.
Q: Are these fuses fast-acting or slow-blow (time-delay)?
A: These are fast-acting (quick-blow) disposable SMD fuses, meaning they interrupt the circuit rapidly upon reaching the rated overcurrent threshold. They are ideal for protecting sensitive electronic components from instantaneous current surges and short circuits. Always match the fuse current rating to your circuit's requirements for optimal protection.
Q: Can these SMD fuses be reused after they blow?
A: No. These are disposable, one-time-use fuses. Once a fuse has interrupted the circuit due to an overcurrent event, it must be replaced with a new one of the same rating. This ensures consistent and reliable protection for your circuit boards every time.
Q: What voltage rating should I choose — 32V or 63V?
A: Select the voltage rating that meets or exceeds the maximum voltage in your circuit. For circuits operating at up to 32V DC, the 32V-rated fuses are suitable. For higher-voltage applications up to 63V DC, choose the 63V-rated variants. Both are well within the EU LVD low-voltage classification (below 75Vdc).
