PNM

Vishay Thin Film

Precision Thin Film Non-Magnetic Resistor,

Surface Mount Chip, ± 25 ppm/°C, Tolerances to 0.1 %

These devices eliminate materials that would disturb

magnetic fields applications such as in MRI magnetic

resonance imaging machines. The PNM series chip resistor

has been carefully engineered with non-magnetic materials

to eliminate the effects of these stray magnetic fields on

circuit performance, thereby resulting in simplified shielding

requirements

and

improved

sound

quality

in

audio

applications.

Providing

signal

conditioning

without

distortion from magnetic fields.
