Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

Recently, Vishay Intertechnology, Inc. It is announced that its AC03-CS series axial wound safety resistors now offer a flexible wire option for easy handling and processing, namely the WSZ lead type option, enabling the device to be used as a surface mount component, thereby reducing assembly time and costs.

The Vishay Draloric AC03-CS series resistors can be used as inrush current limiting resistors during normal operation, as well as pre-charge, discharge and buffer resistors. These devices are designed to ensure that automotive electronics, energy meters, industrial drives and household appliance power supplies fuse safely and quietly in the event of high DC voltage overload or accidental application of 120 VRMS / 240 VRMS AC main voltage.

For challenging working conditions, these devices have an operating temperature range from -40 C to +200 C and are coated with a strong and flame-retardant silicone cement that complies with UL 94 V-0 standards. This coating enables the resistor to protect the printed circuit board and other components, minimizing the risk of fire due to extreme electrical overload without the need for additional series fuses.

The AC03-CS series complies with the AEC-Q200 standard and has a high surge voltage capability of up to 4 kV (according to IEC 61000-4-5 standard, 1.2/50 µs pulse), with a rated power of 3 W at an ambient temperature of 40 C. The resistance range of these devices is from 1 Ω to 100 Ω, with a resistance tolerance of ± 5% and a temperature coefficient (TCR) of ± 200 ppm/K. These resistors comply with RoHS standards, are halogen-free, meet Vishay's green standards, and feature tin-plated termination to be compatible with both lead-free (Pb) and lead-containing (Pb) soldering processes.

Samples of the AC03-CS series resistors are now available and mass production has been achieved. The supply cycle is 12 weeks. For more information about Vishay, please visit www.vishay.com.
