Low-Profile Surface Mount Inductors Ideal for Tight Spaces On Small PCBs

Nov. 7, 2006
Designers of small, compact or portable electronic equipment trying to pack lots of functionality into their layouts for printed circuit boards (PCB’s) will find the new low-profile DR331-5 Surface Mount Inductor from Datatronic Distribution, Inc., offers outstanding EMI protection performance and reliability in a miniature package. The tiny DR331-5 surface mount inductor stands a mere 1-mm (0.39 inch) tall and is only 6.70 (w) -x- 5.60 (l) mm (0.263-x-0.220 inches). These inductors are ideal for a wide range of portable, compact and miniature devices, such as PDAs, mobile phones, portable hard drives, medical appliances, bar code scanners--wherever high-density circuit board design is a requirement. To protect critical circuits from the dangers of EMI, the DR331-5 surface mount inductor features a wide inductance range from 1.2 to 330 uH, +20 percent. The DCR range is 0.08 to 15 ohms maximum, and the current rating is 2.1 to 0.13 amps. They operate over a wide temperature range from -40 to +85ºC, making them suitable for use in many rugged environments. The DR331-5 surface mount inductors are designed with materials that meet the requirements for RoHS compliance. With their low-profile surface mount package design, high performance over a wide inductance range and rugged design, these inductors are ideal for use in a many different industries, including industrial controls, medical, instrumentation, telecom and computer. The DR331-5 inductor’s flat top design makes it compatible with high-speed pick-and-place assembly equipment, and it is suitable for high-temperature soldering in accordance with J-STD-020C. The DR331-5 is available with either gold wrap around or tin wrap around terminations at no additional charge. They are shipped standard on tape-and-reel with 2,000 pieces provided per reel.
