New Yorker Electronics Releases Precision Thin Film Chip Resistors

15 December 2018

New Yorker Electronics has released the State of the Art (SOTA) Precision Thin Film MIL-PRF-55342 Chip Resistors. The SOTA MIL-PRF-55342 provides established reliability fixed film resistors in a variety of cases, product levels, temperature characteristics, tolerances and termination materials.

These chip resistors are used in a variety of mission critical applications such as avionics, satellites, biomedical, communications and weapons systems. As such, they have strict performance requirements. Each resistor receives power conditioning (burn-in) for 100 hours as part of the group A test. In addition, each manufacturing lot receives a group B test (inspection lot formation is not allowed for T level). SOTA manufactures all T level products by up-screening R or S level resistors, an additional step to further enhance the reliability of the T level.

SOTA MIL-PRF-55342 includes precision and semi-precision part numbers that use thick film and thin film materials and processes to provide the complete range of part numbers. SOTA precision thin film chip resistors have resistance tolerances of ±0.1, ±0.25 and ±0.5 or temperature coefficient of resistance of ±25 and ±50 parts per million (ppm)/°C . Thin film materials are sputter deposited and patterned using photolithography. These thin film resistor materials exhibit low current noise and lower drift than semi-precision thick film resistors.
