High-precision flip chip COTS resistors down to 5Ω, with a TCR of ±0.05 ppm/°C
14.00
The devices feature ultra-low TCR of ±0.05 ppm/°C nominal (0°C to +60°C) and ±0.2 ppm/°C typical (-55°C to +125°C, +25°C ref.) with a load-life stability of ±0.005% at 70°C for 2,000 hours at rated power and ±0.01% at 70°C for 10,000 hours.
Available in five chip sizes ranging from 0805 to 2512, the VFCP series offers high power ratings up to 600mW at +70°C and an excellent power coefficient (ΔR due to self-heating) of ±5 ppm at rated power. The devices feature a wide resistance range from 5 Ω to 125 kΩ, with tight resistance tolerance to ±0.01%. Any conceivable ohmic value within this range, to six digits, is available with no additional cost or lead time effect. Matched resistor sets are available by request.
The flip chip devices are qualified as anti-sulfurated resistors for use in environments with high levels of contamination. In addition, the devices are suitable for use in many alternative energy, RTD, Li-ion battery, 4mA to 20mA current loops, and smart grid applications in which analogue circuitry operates under severe environmental, thermal, and mechanical conditions.
The VFCP resistors’ one-side terminations ensure secure contact during the manufacturing process and save up to 35% PCB space compared with a surface-mount chip with wraparound terminations while also providing better strain relief to eliminate cracked substrates and board delamination. The devices are available with both lead (Pb)-free and tin/lead alloy terminal finishes.
