Vishay Intertechnology Releases New Series of Non-Magnetic, Non-Inductive Axial Lead Wirewound Resistors

Ideal for Audio and Medical Applications, Devices Feature High Power Ratings to 12 W and Operating Temperature to +350 Degrees C

MALVERN, PA--(Marketwired - Apr 17, 2014) - Vishay Intertechnology, Inc. (NYSE: VSH) today introduced a new series of non-magnetic, non-inductive axial lead wirewound resistors with high power ratings to 12 W and high-temperature operation to +350 °C, which is ideal for high-end audio and medical imaging equipment.

For radio frequency (RF) and operational amplifier applications, the non-magnetic and all-welded construction of the Vishay Mills MRA series devices, from the Vishay Dale Resistors division, greatly enhances frequency response. Combined with a non-inductive Ayrton-Perry winding, inductive reactance and signal loss are virtually eliminated.

The resistors provide power ratings from 4 W to 12 W at 25 °C and temperature ranges from -65 °C to +250 °C (characteristic U) and -65 °C to +350 °C (characteristic V). The devices offer resistance from 0.01 ohms to 85.0 kilohms, with tolerances of 1 %, 5 %, and 10 %, and TCR of 90 ppm/°C for resistance below 0.99 ohms, 50 ppm/°C for resistance from 1.0 ohms to 9.9 ohms, and 30 ppm/°C for resistance of 10 ohms and above.

MRA resistors are RoHS-compliant and comply with Vishay Green standards.

Samples and production quantities of the MRA series are available now, with a lead time of six to eight weeks for larger orders.

Vishay Intertechnology, Inc., a Fortune 1000 Company listed on the NYSE (VSH), is one of the world's largest manufacturers of discrete semiconductors (diodes, MOSFETs, and infrared optoelectronics) and passive electronic components (resistors, inductors, and capacitors).
