RY31A speciality MELF resistors combine the advanced

pulse load capability and the suitability for RF

applications in a single component.

They are the perfect choice in high frequency circuit

designs where the parasitic inductance of regular, helical

trimmed resistors can not be accepted, but where also pulse

energies apply. Typical applications are in the fields of

telecommunication equipment and industrial electronics.

RY31A - High Frequency Oxide Film, with the inner and

outer surfaces coated with a special glass, features higher

thermal resistance and larger electric power capacity for

the compact volume. Unlike conventional wire wound type, the volumetric resistance will provide superior

stability versus frequency and excellent durability against transient voltage. RY31A is suitable for the application

with large current as well as high frequency circuit.

In very low resistance values, between 1.0 and 100 ohm, these are available in rated wattage 10W, 25W, 50W,

100W, and 150W packages.

The High-Frequency RY31A Series is RoHS compliant and lead free. For customed designs, tighter tolerances,

non-standard technical requirements, or custom special applications, please contact our sales for more

information.
