Littelfuse Inc. announced that it has introduced the Kxxx1GL Series Multipulse(TM) SIDAC, a thyristor power control device designed for use in 220-240V AC line installations. The thyristor, when coupled with a capacitor and transformer, generates the multiple high voltage pulses required to ignite metal-halide lamps. These new devices offer designers of metal-halide lamp ignition circuits the advantages of lower switching loss for higher pulse voltages, improved tolerance for input voltage variations, and longer pulse durations than the company's earlier Kxxx1G Series devices. The Kxxx01GL Series exhibits lower switching loss than comparable competitive devices, so it can produce higher pulse voltages for pulse-start type ignition circuits. Although the Kxxx1GL Series Multipulse SIDAC is available in three versions for high design flexibility, other suppliers offer only two versions. The turn-on characteristics of the Kxxx1GL Series have been modified and the switching loss lowered to match the latest igniter circuit designs, so these new devices can generate at least 20% higher pulse voltages than the earlier Kxxx1G Series. Typical applications of the Kxxx1GL Series include use in metal-halide lamp igniter circuits in medium to large scale metal-halide lamp installations, such as in gyms, street lighting, and sports stadium illumination. The Kxxx1GL Series Multipulse SIDAC offers these key features and benefits: Features: Lower switching loss than earlier Kxxx1G Series Multipulse SIDAC; Tighter breakover/trigger voltage (VBO) control than Kxxx1G Series; Lower dynamic holding current (IH) than Kxxx1G Series; Generates a minimum of three pulses per AC half-cycle. Benefits: Can generate at least 20% higher pulse voltages; Improved operating tolerance for the AC input voltage variations that are common in developing countries; Longer high voltage pulse duration; Best suited for metal-halide lamp ignition applications.

Littelfuse Inc. reported unaudited consolidated earnings results for the first quarter ended March 29, 2013. For the period, the company reported net income of $14,794,000, net income available to common shareholders was $14,775,000 or $0.67 per basic share and $0.66 per diluted share on net sales of $170,918,000 against net income of $17,563,000, net income available to common shareholders was $17,514,000 or $0.81 per basic share and $0.80 per diluted share on net sales of $160,578,000 a year ago. Operating income was $28,117,000 compared to $25,824,000 a year ago. Income before income taxes was $17,972,000 compared to $24,775,000 a year ago. Net cash provided by operating activities was $16,045,000 compared to $7,864,000 a year ago, primarily reflecting excellent working capital performance. Purchases of property, plant and equipment was $5,453,000 compared to $3,244,000 a year ago. The increase in sales was broad based, as all businesses and all geographies grew compared to the prior year. Sales for the second quarter of 2013 are expected to be in the range of $177 to $187 million which represents 1% to 6% growth compared to the second quarter of 2012. Earnings are expected to be in the range of $1.03 to $1.18 per diluted share. This implies an operating margin in the 18% range and a tax rate of approximately 26%. Both the sales and earnings guidance above excludes Hamlin. The company will pay a cash dividend of $0.20 per common share on June 6, 2013 to shareholders of record at the close of business on May 20, 2013.
