MICA Capactiors

As the inventor of the mica capacitor, Cornell Dubilier is the world’s foremost authority and largest manufacturer of mica dielectric capacitors. Our RF mica capacitors feature superior high Q performance without the undesirable properties associated with ceramic and porcelain capacitors. Cornell Dubilier 


Allegro's AMT49406 is a 3-phase, sensorless, brushless DC (BLDC) motor driver (gate driver) which can operate from 5.5 to 50 V—Allegro’s first QuietMotion solution. The AMT49406 is ideal for ceiling fans, pedestal fans, bathroom exhaust fans and home appliance fans and pumps. This device will provide reliable, efficient and low audible noise performance while greatly simplifying design.

Energy Dense, 5,000 hr

Thinpack Aluminum Cap

THA and THAS Series Thinpack capacitors raise the rated life to 5,000 hours, a 66% increase over the 1st-gen devices. Still very high energy density.

A single THA/THAS capacitor can replace an entire board full of SMT, axial or radial aluminum electrolytic or solid tantalum capacitance arrays.
