BLX-A 5 x 20 mm PCB Fuse Holder by Styquenzer – Black Plastic 30 Pack

Description

Product Overview

The BLX-A 5 x 20 mm PCB fuse holder is engineered for high‑reliability applications where consistent circuit protection is essential. Each holder is constructed from a durable black polymer that resists heat buildup while providing a non‑conductive barrier, and the integrated brass terminals ensure a low‑resistance path for current flow. The design follows industry‑standard dimensions, allowing seamless integration with 5 × 20 mm glass or ceramic fuses, and the spring‑loaded contacts guarantee a secure grip that prevents arcing even under transient overload conditions. With a rated current of 10 A and a voltage tolerance of up to 250 V, these holders are suitable for a broad spectrum of devices ranging from consumer‑grade household appliances to rugged industrial control panels.

Beyond the core electrical specifications, the BLX-A holders feature a tool‑free snap‑in mounting system that eliminates the need for soldering, thereby reducing assembly time and minimizing the risk of thermal damage to sensitive components. The holders can be directly inserted into pre‑drilled PCB holes or mounted onto standard breadboard strips, offering flexibility for both prototype development and mass‑production environments. The compact footprint—measuring just 1.18 × 1.18 × 0.55 inches—allows dense placement on high‑density boards without compromising mechanical stability.

In addition to the functional benefits, the product package includes 30 individual holders, providing a cost‑effective bulk solution for manufacturers, repair technicians, and hobbyists alike. The bulk quantity ensures that spare parts are readily available for maintenance cycles, reducing downtime and inventory overhead. Each holder is individually inspected for quality assurance, guaranteeing that every unit meets the stringent performance criteria required for reliable operation in demanding electrical systems.

The BLX-A series is backed by Styquenzer’s commitment to quality and durability. The polymer housing is flame‑retardant, complying with UL94 V‑0 standards, which adds an extra layer of safety in applications where fire resistance is a critical requirement. The brass terminals are plated to resist corrosion, extending the service life of the holder even in harsh environments such as marine, mining, or high‑temperature industrial settings. This combination of material science and thoughtful engineering makes the BLX-A fuse holder a trusted component for long‑term reliability.

Usage

These fuse holders excel in a variety of real‑world scenarios. In household appliances such as washing machines, refrigerators, and microwave ovens, the BLX-A provides a quick‑replaceable fuse solution that safeguards power circuits against overloads and short circuits. For telecommunications equipment, including routers, switches, and power distribution units, the holders ensure uninterrupted service by protecting critical line cards and power supplies from transient spikes.

Industrial users benefit from the holder’s robust construction when deploying them in machine tools, CNC equipment, and automated assembly lines. The ability to operate reliably from –40 °C to 105 °C means the holders can withstand the temperature fluctuations typical of factory floors, outdoor installations, and even aerospace applications where thermal extremes are common. The snap‑in feature simplifies field repairs, allowing technicians to replace fuses without specialized tools, thereby reducing service time and labor costs.

For electronics hobbyists and educational institutions, the BLX-A holders provide an excellent teaching tool for demonstrating circuit protection concepts. Their compatibility with breadboards and standard PCBs makes them ideal for laboratory experiments, prototype builds, and student projects that require safe and reusable fuse solutions. The clear visual design of the black housing and brass contacts also aids in quick identification during troubleshooting sessions.
