Keywords:Gina Roos  KOA Speer  HV73  chip resistor 

KOA Speer Electronics has introduced the HV73 series of high-voltage thickfilm flat chip resistors with a maximum working voltage of 500V.

The HV73 series chip resistors are said to provide superior capabilities compared to standard thickfilm flat chip resistors at the maximum working voltage. Devices in the series include the 1J device rated at 350V, 2A with a resistance value range of 10 kΩ to 10 MΩ and the 2B chip rated at 500 V with a resistance value range of 100 kΩ to 10 MΩ. Resistance tolerances are available at 0.5 per cent, one per cent, two per cent and five per cent. The 1J chip resistor is packaged in an 0603 case size and the 2B is available in a 1206 package.

The company said the HV73 chip resistors reduce spacing requirements and may decrease the total number of resistors needed in high-voltage applications. In addition, the metal glaze thickfilm provides excellent heat and moisture resistance. The resistors are Pb-free, RoHS compliant devices. Applications include camera strobes, LCD monitors, navigational equipment and dc/ac invertors for use in LCD TVs.

Pricing is approximately Rs.6.42 (14 cents) each at 5,000 pieces per reel in small quantities. Delivery is nine to 11 weeks.
