251T Series

Face-down Terminal
Complete lead-free

We developed low profile series of type 251 which is widely used in portable information and telecommunication equipments such as mobile phone, smartphone and portable AV equipments such as digital video camera, digital still camera and portable audio. Type 251 T series will considerably contribute to ultra-miniaturization, ultra-low profile and improvement of performance of the portable multimedia devices.

Features

  • Using the face-down terminal structure makes it possible to design the land in almost the same size as the terminal. As the result of this, parts can be downsized, and the mounting area can be reduced to 1/2 to 1/3 of that required by conventional structures.
  • Ultra low profile height 0.6mm and 0.8mm is applicable.
  • Type 251 T series in size from 1608 to 3216 are applicable to a wide capacitance range from 4.7 to 68 μF.
  • This type of capacitors is suitable for ultra miniaturized, such as DVC, DSC and PCMCIA cards, and high-function compact portable devices, such as mobile phone and smartphone.
  • Case M (face-down terminal type 1608) and case S (face-down terminal type 2012) of this type are listed in the Surface Mounting Device-Outline Registration System of Electronic Device Registration Center of JEITA.
  • Lead-free and RoHS Compliant.
