Ultra-thin Polymer

The new PPC Series of ultra-thin polymer aluminum electrolytic capacitors from Cornell Dubilier represents a totally new capacitor form factor. Designed specifically for applications requiring high ripple current and the thinnest possible profiles, type PPC opens up new product design options.

CDE Thinpack THA capacitor

Space-saving and Less component by THA capacitors (left) versus an SMT aluminum electrolytic (center) and axial aluminum electrolytic bank (right) are substantial.

Silicon Carbide SiC Mosfet

GeneSiC is excited to announce the release of our awaited SiC MOSFETs and next generation of SiC Schottky MPS™ diodes. Range from 20 (mΩ) to 1,000 (mΩ) RDS(ON) Typical 25°C

Temperature Sensors

[Tateyama Kagaku Ind. Co., Ltd.] temperature control for fry oil. Highly reliable and accurate. Necessary for home safety

Brushless DC drivers [Allegro MicroSystems, LLC]

Really quiet. Easy to implement. Extremely efficient. Allegro’s QuietMotion family offers the first-to-market (FOC) brushless DC (BLDC) controllers that are customer code-free. Short to two weeks design cycle time with simple GUI.

Evaluation board speed up the design cycle time

Besides sample, we have field application engineers (FAEs) to provide evaluation board to our customers. As well as assist to product development.

about us

Richwood Electronics Co., Ltd. was founded in 1990, as an electronics component Representatives/Distributors. We aim to create new opportunities by introducing the state-of-art technology and products to customers in Hong Kong, China and the Philippines. To so do, Richwood offers a one-stop total solution to facilitate design and reduce substantial development life cycle and cost.

In recent years, given the US-China trade wars, Richwood also serves as an Asia stocking warehouse and provide quality control and logistics services. This greatly reduces tariffs and shortens the lead-time to delivery products to customers.
