January 30, 2013 - Providing power ratings from 1–6 W at ambient temperature of 40C and 0.9–5.4 W at 70C, Z300-C Series offers resistance from 0.15 Ω to 10 kΩ, resistance tolerances of 5% and 10%, and TCR of 200 ppm/K. Devices feature non-flammable cement coatings and ceramic cores for safety in overload conditions. Designed to limit in-rush currents during surges, RoHS-compliant resistors are optimized for power supplies in electronic meters, industrial and home appliances, and electronic ballasts.

63 Lincoln Hwy., P.O. Box 4004
Malvern, PA, 19355

Press release date: January 28, 2013

MALVERN, Pa. — JanVishay Intertechnology, Inc. (NYSE: VSH) today introduced a new series of axial cemented wirewound resistors that are the industry's first to offer a customized high-voltage surge withstanding capability up to 12 kV.

Designed to limit in-rush currents during high voltage surges, the Vishay Draloric devices are optimized for power supplies in electronic meters, industrial and home appliances, and electronic ballasts. For increased safety in overload conditions, the devices feature non-flammable cement coatings and high-grade ceramic cores.

The Z300-C series features a high-voltage surge withstand capability up to 12 kV as per IEC 61000-4-5 (1.2 s/50 s). The maximum allowed surge handling capacity depends on the resistor model and ohmic value.

The resistors provide a power rating from 1 W to 6 W at an ambient temperature of 40 C and 0.9 W to 5.4 W at 70 C. The devices offer resistance from 0.15Ω to 10 kΩ (with other values available on request), resistance tolerances of 5 % and 10 %, and temperature coefficient (TCR) of 200 ppm/K ( 400 ppm/K for resistance values below 1 Ω).

Z300-C resistors are RoHS-compliant and comply with Vishay "Green" standards.

Device Specification Table:
Model Power rating P40 (W) Power rating P70 (W) Resistance range (Ω)
Z301-C 1 0.9 0.30 to 2 k
ZDA0411-C 2 1.8 0.47 to 4.3 k
Z302-C 3 2.5 0.22 to 3.3 k
Z303-C 4 3.5 0.47 to 3.9 k
Z304-C 5 4.7 0.62 to 5.6 k
Z305-C 6 5.4 0.15 to 10 k

Samples and production quantities of the Z300-C series devices are available now, with lead times of eight to 10 weeks for larger orders. Pricing for U.S. delivery varies according to power rating and resistance value. As an example, distribution pricing for a 4 W, 1.5 kΩ device with 12 kV surge protection is $0.175 per piece in 50,000-piece quantities. Follow wirewound resistors from Vishay at
