This document serves as a comprehensive guide on the N Series SMD Micro Fuses, emphasizing their high quality and competitive pricing. It covers various series such as N-0603 and N-1206, detailing specifications, features, and testing procedures.
The N Series SMD Micro Fuses are designed for over-current protection at the PCB level, available in fast-acting and time-delay types. They utilize Wire Bonding Technology, enhancing temperature and voltage operating ranges. The fuses are environmentally friendly, being Pb Free, RoHS, Halogen Free, and Antimony Free.
Each series within the N Series has specific electrical characteristics. For example, the N-0603 F Series operates at DC 32/63 V with a fast-acting type, while the N-1206 T Series is a time-delay type. The fuses have varying ampere ratings and opening times at 25ºC, with agency approvals under E328408.
The document outlines performance characteristics and testing conditions for the fuses, including resistivity, time/current characteristics, temperature rising, and cycling tests. The endurance test ensures that the voltage drop does not exceed 10% after testing.
The fuses are designed to withstand temperatures from -40℃ to +125℃. Soldering conditions include pre-heating at 150℃ ±10℃, solder bath at 245℃±5℃, and reflow at 260℃ ± 10℃.
The N6125 C Series SMD fuses are fast-acting and high-current types, with precise dimensions provided. They operate at DC 65/125V and AC 125V.
The fuses are environmentally conscious, complying with REACH (SVHC) and RoHS standards, designed to protect PCBs against ambient temperature variations.
The SMD Micro fuse is essential for protecting electronic devices such as telecommunications equipment, home appliances, and IT industry devices from unexpected surge currents.
The product line is certified under ISO 9001, 14001, and various international standards, including Underwriters Laboratories, CB Scheme, Korea Certification, and Europe Certification. The fuses are RoHS Free, Pb Free, Halogen Free, and Antimony Free.
