switch mode power supply - smps transformer capacitance effects


What are effects of interwinding capacitance in smps power transformer? What is the influence? For example, i have 83khz smps transformer with windings made of litz wire. The capacitance between windings is 250pF (i measured it by short-circuiting both windings and using u1732c agilent RLC meter). Is it good or bad? Is electrostatic shield between primary and secondary helpful to reduce value of inter-winding capacitance?

arduino - Can I use TI's cc2541 BLE as micro controller to perform operations/ processing instead of ATmega328P AU to save cost?

I am using arduino pro mini (which contains Atmega328p AU ) along with cc2541(HM-10) to process and transfer data over BLE to smartphone. I...
