III. Analysis of Planar Thick - Film Technology

Core of the Process

An alumina ceramic substrate (with a purity of 96% - 99%) is used. A serpentine resistance path is formed through the thick - film printing process to reduce inductance (<50nH) and improve high - frequency characteristics.

Performance - Enhanced Design

Voltage Coefficient Optimization

The Vishay TR series achieves a voltage coefficient of <1ppm/V through laser trimming technology.

Packaging Materials

Silicone resin (resistant to high temperatures up to +210°C) or epoxy resin (moisture - proof and chemical - corrosion resistant)

Test Standards

Life Test

MIL - STD - 202 1000 - hour load life test (≤±0.5%)

Environmental Adaptability

Thermal shock test from - 55°C to +225°C (≤±0.2%)
