TYPICAL APPLICATIONS

The usage of HIA series resistors will expand circuit design limits significantly because they have precision resistor characteristics with low TC and are able to carry load at high ambient temperatures.

HIA series can effectively be used in all industrial, electrical, electronic and telecommunication equipment where large power dissipation is required (e.g. when used as a voltage divider or bleeder resistor in DC power supplies or for series dropping). They are generally satisfactory for use at frequencies up to 50KHz.

Series RSR

• Type ‘A’ compatible for using with Amp type connectors.

• Flame retardant coating compatible with UL standards.

TYPICAL APPLICATIONS

In RSR series, a corrugated alloy tape is wound edgewise or flat onto a ceramic tube which is coated with a silicone cement which is compatible with UL standards. This ribbed construction puts both sides of the resistive element in contact with air thus creating a convention area four times greater than that obtained with normal wire wound resistors. These resistors are designed primarily to withstand heavy overload surges up to max 7 times their rated wattage for 10 to 15 seconds (max). This characteristic makes them most suitable for controlling motors requiring high dissipation, low resistance values and high current capacity.
