Surface Mount CCFL High Voltage Inverter Transformer for Consumer Electronic Applications and Liquid Crystal Display
GARDENA, Calif. - Feb. 14, 2003 - J.W. Miller, a leading provider of custom and standard magnetic components, has introduced the new cold cathode fluorescent lamp (CCFL) Inverter
Transformer series in a surface mount package. This device is an integral component used in power supplies for producing the high voltage needed to initiate lamp operation for back-lighting of liquid crystal displays (LCD). Applications are found in notebook and handheld computers, flat panel home entertainment displays, point-of-sale terminals, portable instruments, and automotive and medical monitors.
Key performance characteristics include an operating frequency of 60KHz -/+25 %, operating temperature of 0 to +75°C, and dielectric strength of 1500Vrms. Available in five 6-watt configurations, input voltage selections include 25, 20, 15, 13, or 10.5V with outputs of 1300V, 7OmA. The surface mount package measures 26 x 16.5 x 7.1 mm and features a multi-sectional bobbin constructicn to prevent high voltage breakdown. Transformers are shipped in bulk and priced from $2.09 in
production quantities of 500.
J.W. Miller offers a full line of high-quality surface-mount and through-hole coils, chokes, inductors and transformers for short run or high volume production requirements and maintains a
large inventory of standard components for quick delivery. Engineering assistance, product samples and custom designs are always available. J.W. Miller products can be purchased through
the company's global network of distributors and manufacturer's representatives (see the web site for locations).
