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. 

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 

BLDC FOC

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.

Application: 

Tablets, laptops,

LED driver modules, compact power supplies, drones and, solid state drives

SiC Schottky Diodes

SemiQ (previously Global Power Technologies Group) has released to production of its new 3rd generation silicon carbide (SiC) diode family featuring blocking voltages of 650V, 1200V and 1700V with forward current 8A up to 50A per chip. 

These Gen-3 products represent a huge improvement in reliability, device ruggedness, surge current capability, and moisture resistance. Extensive qualification testing includes over eight million device hours of HTRB and H3TRB.
