Axial Cemented Wirewound Resistor has 2 kV surge capability.
Press Release Summary:
Featuring fusing time of less than 30 sec for 45 W overload, AC03..CS offers cement coating for immediate interruption without flame and explosion when mains voltage (220 Vrms) is applied and acts as in-rush current-limiting resistor during normal operation. Lacquer coating matches thermal and electrical insulating properties of silicone cement. Along with 2 kV (30 pulses/15 min) surge capability, features include 10–100 Ω resistance, ±5% resistance tolerance, and ±200 ppm/K TCR.
Original Press Release:
Vishay Intertechnology Releases Axial Cemented Wirewound Safety Resistor with Surge Withstanding Capability of 2 kV and Fusing Time of < 30 s for 45 W Overload
Device Features Special Cement Coating for Safe and Silent Fusing Operation in Electric Appliances, Energy Meters, and Power Supplies
MALVERN, Pa. — Vishay Intertechnology, Inc. (NYSE: VSH) today introduced a new axial cemented wirewound safety resistor specially designed to ensure safe and silent fusing operation during overload conditions in electric appliances, energy meters, and power supplies. Featuring a fusing time of < 30 s for a 45 W overload and high surge voltage capability, the new Vishay Draloric AC03..CS offers a special cement coating for immediate interruption without flame and explosion when mains voltage (220 Vrms) is applied.
In addition to fusing "without a bang" in electric appliances such as washing machines and shaver chargers, the AC03..CS safety resistor acts as an in-rush current-limiting resistor during normal operation. The device's specially developed lacquer coating matches the thermal and electrical insulating properties of standard silicone cement. This allows designers to meet the requirements for UL approval more easily and eliminates the need to utilize additional fuses in series with the input resistor.
The AC03..CS features a surge voltage capability of 2 kV (30 pulses/15 min.) as per IEC 61000-4-5, with higher surge capability available on request. The resistor provides a power rating of 3 W at an ambient temperature of 40 ºC and 2.5 W at 70 ºC. The RoHS-compliant device offers resistance from 10Â Ω to 100 Ω, resistance tolerance of ± 5 %, and temperature coefficient (TCR) of ± 200 ppm/K.
Samples and production quantities of the AC03..CS safety resistor are available now, with lead times of eight to 10 weeks for larger orders. Pricing for U.S. delivery starts at $0.15 per piece.
