Marking the 22 years of business career as of 2012, RARA Electronics has been steadily growing into a professional high power resistor manufacturer. RARA Electronics Corporation manufactures metal clad wire-wound high power resistors that are flexible, durable and conform to international materials specifications such as RoHS and WEEE.
The product, which wattage range begins at 60W is a powerful, economical 2800W model, meeting the ULⓇ and IP65 certifications. The wire-wound element configurations can absorb large amounts of pulsed power with safety. These models come with an aluminum case that adds durability and enhances hearing conduction away from the components. There are several case configurations to suit application needs. Configurations include: Vertical, horizontal, flat and narrow.
Models come standard with ¡°easy attachment¡± tab terminals. Flying leads and ¡°L¡± terminals are also an option. Other options include non-inductive windings and thermostat installation. RARA¡¯s resistor range can handle any high power need. The company also specializes in designing products for difficult applications.
< Current Sensing Resistor >
RARA¡¯s shunt resistors were originally designed as custom orders and therefore come in a wide selection of sizes, packages and power ratings that range from one to one thousand amps. Some standard applications for these units are: Battery Management systems; ECU, ABS, EPs of Automobiles; Electricity Meters; Panel Meters; BLDC Motor Drives; and AC/DC Motor controllers.
Since 2008, the company has been supplying shunt resistors that can handle massive power ratings of 100 up to 1000A. These were designed primarily for the testing and design of electric vehicles.
< Precision Thin Film Resistors >
The products are high precision, thin film resistors. A standard TCR of 2ppm/¡ÆC is achieved with a Ni-Cr-Si alloy spattered onto an alumina substrate. Operating temperatures ranged from -55¡ÆC to +125¡ÆC.
These models can also exhibit excellent long-term stability, low current noise, a low voltage coefficient and a low thermal EMF. Typical applications are: Discrete voltage dividers, analogue circuits in industrial measuring equipment, control, medical electronics, ATE, aerospace, and reliable power electronics. The company has committed to: the production of high quality products, an ongoing R&D program, and unparalleled customer service, etc.
