## **SPECIFICATION**
## **DESCRIPTION**
An effi cient and compact electrical audio transformer, the VTX146-0001 Series is specifi cally used in audio equipment to convert high-voltage AC mains power into the required voltages suitable for use by audio circuits. Its toroidal (donut-shaped) core design minimises electromagnetic interference (EMI) and hum, resulting in cleaner power delivery and improved sound quality. It is favoured in high-fi delity audio systems for its low noise, high effi ciency, and compact size. These toroidals are made with 2 layers of GOSS band shielding for added noise elimination.
## Audio grade grain orientated silicon steel core
2 layer GOSS band shielding
Silent operation and high effi ciency (>83%)
Centre potted with captive nut in centre
Wide input voltage range from 110 to 240V AC

About Novapart
Novapart is a B2B electronic component broker specialising in stock shortages and cost reduction. We source hard-to-find parts and identify compliant alternatives across a catalogue of 410,000+ components from 500+ manufacturers.
Learn more →Stock Shortage Specialist
When a component is unavailable, discontinued or has an unacceptable lead time, we tap into our network of vetted European and Asian distributors to source what you need — without compromising on quality or traceability.
Request a quote →Compliant Alternatives
We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
