High-voltage resistors with tight tolerance
28 April 2010
Passive Components
Murata’s MHR03xx series of high-voltage resistors is now available with tighter tolerances than in previous versions.
Parts in the range 1 MΩ to 100 MΩ are available with ±0,5% tolerances, and parts up to 500 MΩ can be produced with tolerances of ±w1%. The MHR03xx series can operate up to 14 kV d.c., depending on the part number.
The smallest part in the range is the MHR0307SA, available in 1 to 500 MΩ versions with operating voltage up to 3,0 kV d.c. and rated power of 0,3 W. It measures 7,6 x 5,0 x 2,5 mm with a lead pitch of 5,08 mm. At the other end of the range, the MHR0319SA measures 20,2 x 5,0 x 2,5 mm with a lead pitch of 17,78 mm. These resistors can operate up to 14 kV d.c. with rated power of 1,0 W and are available up to 1000 MΩ.
The MHR03xx series is ideal for use in high-voltage power supplies and high-voltage transformers. Applications include office equipment such as laser printers and photocopiers, airconditioning systems, household appliances such as washing machines and refrigerators, beauty appliances such as hair dryers, automotive electronics including diesel particulate filters, some medical electronics applications including X-ray machines and defibrillators, and many more.
