Long Lead Wirewound Enameled Resistors - DRB16
DeMint Electonics provides (DRB16) Long Lead Wirewound Enameled Resistor. Long leads give two types of installation in vertical and horizontal leads with competitive prices. Resistance range from 1Ω to 10KΩ, power range from 3W ~ 20W, and the highest operating voltage from 120V to 750V are availible. Size and specification match the industry standard.
The vertical and horizontal lead type glass glaze resistor is the resistance wiring around the heat-resistant porcelain body. Surface coated with wet-resistant, heat-resistant, non-corrosive coatings (such as silicone, epoxy resin, cement, glaze porcelain, etc.) for protection. Its characteristics are: small temperature coefficient, excellent heat resistance, light weight, low noise, overload resistance, low resistance change rate, and better heat transfer characteristics than conventional wire-wound power resistors. Lead-free product (DRB16) meets RoHS Standard and lead-free standard.
The vitreous enamelled resistor (DRB16) is used to replace the traditional paint of the resistance body, and the resistance caused by the unbearable thermal stress "high temperature". (DRB16) provides durable lead-free enameled coatings that allow wirewound resistors to maintain a hardened coating that can be worked in high temperature environments. The fully welded structure strengthens the mechanical integrity.
When cost, quality, and reliability are key factors, the power type (DRB16) line winding is the best choice. It can provide Ayrton Perry line-winding application requirements. These (DRB16) come with short production cycle, and widely used in power tools, switch applications, power supplies, welding machines, high voltage applications, consumer product applications, home entertainment, home appliances products. For the customized special applications, please contact our sales to discuss the details.
