This release in:

MALVERN, Pa. — April 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 Ω to 85.0 kΩ, with tolerances of 1 %, 5 %, and 10 %, and TCR of 90 ppm/C for resistance below 0.99 ?, 50 ppm/C for resistance from 1.0 Ω to 9.9 Ω, and 30 ppm/C for resistance of 10 Ω and above.

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

Device Specification Table:

Model Power Rating P25 C (W) Resistance Range (Ω)
Characteristic U +250 C Characteristic V +350 C
MRA-05 4.0 5.0 0.01 to 15.0 k
MRA-10 7.0 10.0 0.05 to 35.0 k
MRA-12 10.0 12.0 0.05 to 85.0 k
