SURFACE MOUNT CHIPS PNM Vishay Thin Film Precision Thin Film Non-Magnetic Chip Resistors 25 ppm/C, Tolerances to 0.1 % FEATURES Non-magnetic Lead (Pb)-free or Sn/Pb terminations available Moisture resistant High purity alumina substrate Actual Size Non-standard values available 1505 Will pass + 85 C, 85 % relative humidity and These devices eliminate materials that would disturb 10 % rated power magnetic fields applications such as in MRI magnetic 100 % visual inspected per MIL-PRF-55342 resonance imaging machines. The PNM series chip resistor Very low noise and voltage coefficient (< - 30 dB) has been carefully engineered with non-magnetic materials to eliminate the effects of these stray magnetic fields on Non-inductive circuit performance, thereby resulting in simplified shielding Laser-trimmed tolerances to 0.1 % requirements and improved sound quality in audio Wraparound resistance less than 10 m applications. Providing signal conditioning without distortion Halogen-free according to IEC 61249-2-21 definition from magnetic fields. available CONSTRUCTION Compiant to RoHS directive 2002/95/EC Tantalum Nitride Resistive Film Passivation Solder TYPICAL PERFORMANCE coating ABS Barrier layer High Purity TCR 25 Alumina Substrate TOL 0.1 Adhesion layer STANDARD ELECTRICAL SPECIFICATIONS TEST SPECIFICATIONS CONDITIONS Material Tantalum nitride Absolute TCR 25 ppm/C, 50 ppm/C, 100 ppm/C - 55 C to + 125 C Absolute Tolerance 1.0 %, 0.5 % and 0.1 % + 25 C Operating Temperature Range - 55 C to + 125 C Noise < - 25 dB CASE SIZE POWER RATING (mW) MAX.
