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.
