A Series PulsEater(R) Ceramic Composition Available in E12 Ohmic values 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 flammability rating which is suitable for almost any environment. *AZ style is provided with dual terminal wires F eat u res A pp l ications * High Surge Energy * Non-Inductive * Small Size * Motor Drives * Power Supplies, UPS * Power Conversion * In-Rush Current Limiting S E R I E S S P E C I F I C AT I O N S Resistance1 Series (ohms) AV 3.3 to 10K AW 4.7 to 15K AX 1.0 to 3.3K AY 2.2 to 6.8K AZ 1.5 to 4.7K 1E12 P avg.2 (watts) 2.0 2.5 3.5 4.5 5.5 Impulse Voltage3 (volts) 1000 1500 1000 2000 2500 Energy4 (joule) 250 400 700 1400 2800 Standard Values 10%; 2Free Air 40C Ambient; 3In Air; 4Single Impulse c h aracteritics Resistance Element Bulk Ceramic Terminals Radial; 100% Sn solder coated radial (60/40 solder available upon request) Coating UL94V0, solvent resistant epoxy Tolerance 10% Standard Operating Temp. -55C to 150C Range Derating Derates linearly from 100% @ 50C to 0% @ 150C Temperature Rise 100C @ 100% rated power, 50C ambient Mounting clip D H L Dim.
