AZ series also available

THE “A” SERIES NON-INDUCTIVE,

CERAMIC COMPOSITE RESISTORS

ARE DESIGNED FOR A VARIETY

OF APPLICATIONS WHERE HIGH

ENERGY HANDLING CAPABILITIES

ARE CRUCIAL. THESE RESISTORS ARE

IDEAL FOR ANY APPLICATION WHICH

IS SUBJECT TO SURGES, HIGH PEAK

POWER, OR IMPULSE ENERGY.

THEIR UNIQUE DESIGN ALLOWS

UNIFORM DISTRIBUTION OF ENERGY

THROUGHOUT THEIR STRUCTURE

WHICH RESULTS IN LOW THERMAL

STRESS. THE HIGH-TEMPERATURE,

SOLVENT-RESISTANT EPOXY COATING

CARRIES A UL94V0 FLAMMABIL -

ITY RATING WHICH IS SUITABLE FOR

ALMOST ANY ENVIRONMENT.

APPLICATIONS

? MOTOR DRIVES

? POWER SUPPLIES, UPS

? POWER CONVERSION

? IN-RUSH CURRENT LIMITING

FEATURES

? HIGH SURGE ENERGY

? NON-INDUCTIVE

? SMALL SIZE
