Product Description
Vishay Precision Group (VPG) has introduced two new ultra-high-precision resistors to its Vishay Foil Resistors (VFR) product line. Bulk Metal® Z-Foil current sensing resistors are designed to improve LED brightness and efficiency in portable battery-powered applications.
Screen brightness is a very important function In portable devices’ LED-backlit LCD displays and it is controlled via an LED panel mounted on the rear of the LCD, which boosts the input voltage connected to the panel.
These devices need stable and precise current resistors with low thermal EMF and low absolute TCR to avoid brightness flickering and to control the stability of the LED output voltage.
The LED1625 and LED221 provide low TCR of 0.05 ppm/°C nominal (0°C to +60°C) and 0.2 ppm/°C nominal (–55°C to +125°C,+25°C ref.), load-life stability of ±0.005%, and tight tolerances to ±0.01%. The LED1625 also offers a 1 W power rating and a resistance range from 0.3 Ω to 10 Ω, while the LED221 features power ratings to 8 W and a resistance range from 0.5 Ω to 500 Ω. Any conceivable value within the devices' resistance ranges, to six digits, is available with no additional cost or lead time effect.
The resistors offer PCR (or ΔR due to self heating) of 5 ppm at rated power.
Featuring a non-inductive (< 0.08 μH), non-capacitive design, the LED1625 and LED221 offer a rise time of 1 ns with effectively no ringing, voltage coefficient of < 0.1 ppm/V, current noise of 0.010 μVRMS/V of applied voltage (< –40 dB), and thermal EMF of < 0.05 μV/°C. They withstand ESD spikes to at least 25 kV and are available with lead (Pb)-free and tin/lead alloy terminal finishes. The LED221 is also available with a solderable heatsink tab.
Contract pricing display is unavailable at the moment. Prices shown are standard retail prices, orders placed will have contract pricing applied when processed.
