Lower Range High Voltage Chip Resistors LHVC Series Superior voltage performance over commercial range chips 0805, 1206 and 2010 sizes Resistance 50Kohms to 10Mohms RoHS compliant Electrical Data LHVC0805 LHVC1206 LHVC2010 Power rating at 70C watts 0.125 0.25 0.5 Resistance range ohms 100K to 10M 100K to 10M 50K to 10M Limiting element voltage dc volts 300 400 800 5s Overload voltage dc volts 800 1000 3000 Dielectric withstand voltage volts 500V TCR ppm/°C ±200 Resistance tolerance % 1, 5 Standard values E24 (5% tolerance) & E96 (1% tolerance) Ambient temperature range °C -55 to +155 Physical Data Dimensions in mm Type LW T D1 D2 Nom wt. (g) Construction Pd/Ag terminations are applied to the top and bottom of an alumina substrate. A resistive element is printed between the top face conductors, which is then adjusted to value and protected. A wraparoundc onductor is applied to join the top and bottom sides. The terminations are electroplated with a Ni barrier layer prior to plating with a Sn finish. Solvent Resistance The body protection and marking are resistant to all normal industrial solvents suitable for printed circuits. Flammability The resistor will not burn or emit incandescent particles under any condition of applied temperature or overload. Solderability 95% min coverage (MIL-STD 202F / 208H, 235C 2 secs) Welwyn Components General Note Welwyn Components reserves the right to make changes in product specification without notice or liability.
