High Voltage Divider Resistors HVD Series Physical Data Voltage ratings up to 30kV Non-inductive design Ratio tolerance down to 0.25% TCR tracking down to 25ppm/°C VCR down to -0.15ppm/V Custom design service available RoHS compliant Electrical Data HVD08 HVD12 HVD15 HVD20 HVD30 Limiting element voltage in air dc or ac pk kV 7.5 10 15 20 30 Resistance value ohms 10K – 1G 50K – 2G 100K – 2G 100K – 5G Resistance tolerance % 1, 5 Ratio tolerance % 0.25, 0.5, 1 TCR (20°C to 70°C) ppm/°C 50, 100 Tracking TCR (20°C to 70°C) ppm/°C 25, 50 Standard values E24 preferred for (R1 + R2) and R2 Ambient temperature range °C -55 to +155 Insulation resistance at 500V ohms >10G Dielectric strength of insulation volts >1000 Dimensions in mm, weight in g Type L (±0.5) H (±0.5) T (Max) P (±0.5) (±0.5) LL Lead Length Wt. nom 5.08 ±0.75 0.66 Other resistance, tolerance and TCR values are available on request. Construction Termination conductors and ruthenium oxide resistive material are print- ed in a non-inductive pattern onto the surface of a 96% alumina sub- strate. A screen-printed protection is then applied and terminals are then attached. Terminations Solder coated phosphor bronze leadframe terminations are solder dipped in SnAgCu and meet the following IEC requirements: IEC 68.2.21 – Strength, IEC 115-1, Clause 4.17.3.2 – Solderability Marking Type reference, TCR codes, resistance values, tolerance codes and date code are legend marked. The resistance value code conforms to IEC 62. Solvent Resistance The body protection and marking are resistant to all normal industrial clean- ing solvents suitable for printed circuits. .

High Voltage Divider Resistors HVD Series Application Notes Due to the high voltage, which can appear between the terminations and any adjacent metal part, resistors should be mounted at an adequate distance from other conductors. For some ultra-high voltage applications it is required to immerse the components in oil or SF6 gas or pot them in void-free silicone compound to reduce corona or surface tracking. The printed protection is suitable for these applications. The divider consists of high value R 1 and low value R2. The voltage division ratio of the divider is given by Ratio = R2 : (R1 + R2) Performance Data Maximum Typical Load at rated power: 1000 hours at 70°C ΔR% <100M: 0.25, ≥100M: 0.5 0.1 Overload: 1.5 x rated power not exceeding LEV for 5 seconds ΔR% 0.25 0.1 Moisture resistance: MIL Std. 202, method 106 ΔR% 0.25 0.1 Temperature rapid change: 5cycles -55 / 155°C ΔR% 0.25 0.1 Type Typical VCR (ppm/V) HVD08 -0.50 HVD12 -0.35 HVD15 -0.25 HVD20 -0.20 HVD30 -0.15 Ordering Procedure Example: HVD15 for a voltage ratio of 1:1000, with R1 = 99.9 megohms and R2 = 100 kilohms (total R1 + R2 = 100 megohms) at 50ppm/°C absolute and 25ppm/°C tracking TCR, 1% absolute and 0.5% ratio tolerance.
