| (1/2) 001-01 / 20011102 / e532_RLF12560.fm Inductors For Power Line SMD Accompaning large current power supplies, these inductors have secured efficient characteristics by improving its magnetic circuit based on existing products. These products meet resistance reducing and current enlargement. FEATURES * Comparing with existing products(RLF12545), DC current superimposition characteristic have improved. Especially, inductance rises about 10% in spite of high temperature at 100C. In addition, inductance have risen about 30% at normal temperature. * Using flat-squere wire for winding, that is rising space factor, these inductors can reduce current resistance and suppress calorific value. * Forming internal gap, their structure suppress outgoing magnetic flux leakage. * Completely Pb free for both inside of products and terminal electrodes. APPLICATIONS * Choke coils in power circuit of personal computers, crystal liquid television monitors, set top boxes, amusement equipments, etc. SPECIFICATIONS Type RLF12560 Operating temperature range Storage temperature range [Including self-temperature rise] [Unit of products] -20 to +105C -40 to +105C RLF Series RLF12560 Type PRODUCT IDENTIFICATIONS RLF 12560 T- 1R0 N 140 (1) (2) (3) (4) (5) (6) (1) Series name (2) Dimensions LxWxT 12560 12.5x12.5x6.0mm (3) Packaging style T Taping(reel) (4) Inductance value 1R0 100 1H 10H (5) Inductance tolerance M N 20% 30% (6) Rated current 8R2 140 8.2A 14.4A PACKAGING STYLE AND QUANTITIES Packaging style Taping Type RLF12560T Quantity 500 pieces/reel RECOMMENDED REFLOW SOLDERING CONDITIONS 10s 2603C 230C min.
