Cemented Leaded Wirewound Resistors

The AC series is the perfect choice for general purpose

power applications. The AEC-Q200 qualified AC-AT series

is best suited for automotive applications. The robust silicon

cement coating can handle challenging ambient and

operating conditions. Typical applications include but are

not

limited

to

energy

meters,

power

supplies

and

automotive

electronics.

For

a

given

application,

requirements of ohmic value, rated power, peak voltage,

pulse

shape,

pulse

duration,

lead

bending,

and

environmental conditions may be submitted to recommend

the most suitable product.



Various lead forms are available such as RT (radial taped),

WSZ (Z-form), DK (double kink), EK (single kink) with defined

mounting pitch.
