Withstand Inrush CQ24LT 002 6.1x2.6mm Ceramic Time Lag Chip Fuse 2A 350V 6125 For LED Lighting Overcurrent Protection
Description
2410 wire-in air SMD fuses are very suitable for secondary level over-current protection applications. These lead-free surface mount devices offer increased reliability and have eliminated the risk of end cap removal common in traditional ceramic body fuses. Additionally, the straight in-air wire element has demonstrated consistent fusing and cutting characteristics. These 2410 fuses utilize nickel and tin plated copper terminations and feature high reliability and resilience with strong arc suppression characteristics.
