Product Description
Littelfuse 0154007.DR Non-Resettable Fuse, 7A, time delay, is part of the advanced OMNI-BLOK 154 Series designed for secure and reliable overcurrent protection in a broad array of electronic circuits. Engineered to operate at 125V AC and 125V DC, this fuse is tailored for integration into sensitive and high-value circuits where immediate and dependable response is vital.
This surface-mount fuse features a robust thermoplastic body that guarantees longevity and consistent performance under high-temperature conditions. The OMNI-BLOK design incorporates a holder that supports fast reflow soldering up to 260°C, streamlining both initial installation and eventual fuse replacement without re-exposing PCB components to direct heat. This structure also enables safe, efficient maintenance practices in high-density assemblies.
Non-resettable construction ensures fault clearing and circuit isolation after overcurrent events. 7A current rating at both 125V AC and 125V DC for compatibility in a wide range of applications. Time delay (time-lag) characteristics safeguard semiconductors and critical electronics from transient surges.
OMNI-BLOK fuse-and-holder design enables one-step installation and easy swapping on circuit boards. 5.03 mm width x 3.81 mm height x 9.73 mm depth form factor optimized for tight PCB layouts. Heat-resistant thermoplastic and tin/lead plated beryllium copper alloy terminals ensure durability under cyclic loads.
Complies with safety approvals and standards including RoHS, CSA, and UL 94 V-0. Applicable in industrial, laboratory, IT, automation, and commercial electronics for securing alarm systems, audio/video equipment, portable devices, and more.
The Littelfuse 0154007.DR OMNI-BLOK fuse is ideal for manufacturers and engineers who value space-saving safety solutions on PCB assemblies, requiring minimal downtime and high assurance against overcurrent failures. Thanks to its advanced feature set, it ensures both protection and ease of service in high-density, sensitive, or mission-critical applications.
