Key Features
- 1 GΩ resistance in a 2010 SMD package rated for up to 2000 V working voltage, enabling safe high-voltage divider and sensing circuits
- ±5% tolerance with 100 ppm/°C temperature coefficient, maintaining stable resistance in high-voltage measurement applications
- Thick film construction on a ceramic substrate provides robust dielectric withstand and minimal parasitic capacitance at GΩ-level impedances
Applications
The HVC2010-1G0JT3 is used in high-voltage measurement front-ends, electrostatic discharge (ESD) test instruments, and insulation resistance testers where 1 GΩ series or shunt resistors are required to safely divide or limit kilovolt-level signals. It is also employed in photodetector bias networks and particle physics detector readout circuits where extremely high input impedances at 2000 V are necessary. Medical imaging equipment and X-ray power supplies benefit from this resistor's 2010 form factor and stable 1 GΩ value to set biasing and bleeder currents at high voltage rails.

Frequently Asked Questions
What resistance value and maximum voltage rating does the HVC2010-1G0JT3 carry?
The HVC2010-1G0JT3 has a resistance of 1 GΩ (1,000,000,000 Ω) with a maximum working voltage of 2000 V. These specifications make it uniquely suited for high-voltage divider and leakage current measurement applications where standard 0805 or 1206 resistors would fail from voltage coefficient effects or dielectric breakdown.
How does the 100 ppm/°C TCR of HVC2010-1G0JT3 affect measurement accuracy in varying temperatures?
A 100 ppm/°C temperature coefficient means the 1 GΩ resistance shifts by approximately 10 MΩ per 10°C change. In precision high-voltage dividers operating between -55°C and +155°C, this TCR must be accounted for in calibration to maintain divider ratio accuracy below ±0.5% across the full temperature range.
In which high-voltage circuit types is the HVC2010-1G0JT3 2010 package size preferred over larger through-hole resistors?
The 2010 SMD package allows the HVC2010-1G0JT3 to be placed directly in a surface-mount high-voltage multiplier or bleeder chain, where the 5.08 mm × 2.54 mm footprint fits within compact PCB layouts that cannot accommodate through-hole MELF or axial resistors. This is especially relevant in portable HV test instruments and compact HVDC power supply modules.
How does the HVC2010-1G0JT3 compare to using multiple lower-value resistors in series for 1 GΩ applications?
Using a single HVC2010-1G0JT3 eliminates the series resistance matching problem: stacking ten 100 MΩ resistors introduces cumulative tolerance errors up to ±5% per resistor, while this single part guarantees ±5% total at 1 GΩ. The single-part solution also reduces PCB real estate by roughly 80% and simplifies the BOM for high-voltage divider strings.
