The Kxxx1G L-Series Multipulse SIDAC, introduced by Littelfuse, is a thyristor-based power control device designed for 220-240V AC line applications. These devices are particularly useful in metal halide lamp circuits, where they generate multiple high-voltage pulses when paired with capacitors and transformers. This feature is essential for igniting metal halide bulbs effectively. Compared to earlier versions of the Kxxx1G series, the new Kxxx1GL offers higher pulse voltages, reduced switching losses, and improved tolerance to input voltage fluctuations. This makes them ideal for use in regions where power supply stability may be an issue. The Kxxx1GL also extends the pulse duration, providing more reliable ignition performance. Available in three different configurations, the Kxxx1GL series gives designers greater flexibility than competing products that typically offer only two options. These enhancements make the Kxxx1GL well-suited for large-scale lighting systems such as those found in gyms, street lights, and stadium lighting. According to Koichiro Yoshimoto, Littelfuse’s Thyristor Business Development Manager, "The latest multi-pulse SIDAC thyristor devices deliver superior ignition performance for halogen control circuits. They also provide better resilience to voltage variations commonly seen in developing countries." Key features of the Kxxx1GL series include: - Lower switching losses - Tighter corner/trigger voltage (VBO) control - Reduced dynamic holding current (IH) - At least three pulses per AC half cycle - Pulse voltage increased by at least 20% - Enhanced tolerance to voltage fluctuations - Longer high-voltage pulse duration - Ideal for metal halide lighting applications The Kxxx1G series is available in bulk or tube packaging, with options for 1000 or 5000 units. Large orders can be placed through authorized Littelfuse distributors worldwide.
