High Stability Resistor Chips (< 0.25 % at Pn at 70 °C during 1000 h) Thick Film Technology
Vishay Sfernice thick film resistor chips are specially designed to meet very stringent specifications in terms of reliability, stability < 0.25 % at Pn at + 70 °C during 1000 h, homogeneity, reproducibility and quality.
They conform to specifications NFC 83-240 and MIL-R-55342 D.
Evaluated to ESCC 4001/026 (see CHPHR datasheet).
Sputtered Thin Film terminations, with nickel barrier, are very convenient for high operating conditions. They can withstand thousands of very severe thermal shocks.
B (W/A), N (W/A), and F (one face) types are for solder reflow assembly.
