 All dimensions in mm.

 

Recommended reflow profile.

Reflow soldering, vapour-phase soldering. A maximum soldering temperature of 260ºC during 10 s should not be exceed for (see recommended soldering profile with maximum and minimum temperature-time).

 

 

The reflow condition recommended is according to the machine used by our company. Big differences will arise as a result of the type of machine, reflow conditions, method, etc used. 

  1. Rated Inductance LR: Measured at frequency fL, with impedance analyser WK3260 with 3MHz installed.
  2. Q Factor Qmin: Measured at frequency fL, with impedance analyser WK3260 with 3MHz installed.
  3. Self-resonance frequency fmin Measured at frequency fL, with impedance analyser WK3260 with 3MHz installed.
