Type HVD Ultra-Precision Voltage Dividers
Voltage Ratings up to 5kVDC • Ratio Tol.: 0.05% • Ratio TC: 5 ppm/°C or 10 ppm/°C
Type HVD Ultra-Precision Voltage Divider Networks

These monolithic voltage divider networks that have ceramic-sandwich
construction, offer ultra-precision performance combined with a robusttransient-tolerant design for applications with continuous voltage ratings
up to 5000 Volts DC. The Standard Ratio Tolerance is 0.05% with Ratio
TC options of 5 ppm/°C and 10 ppm/°C.
Type HVD voltage dividers are ideal for precise DC voltage division applications in Test & Measurement Instruments, Medical Equipment, IndustrialEquipment, Materials Analysis and Laboratory Equipment.
For higher precision applications; Ratio Tolerance as tight as 0.01% andRatio TC as low as 2 ppm/°C, see the Type USVD2 Voltage Dividers.
For Voltage Dividers designed for AC Power Quality Monitoring/Metering
applications, see the Type VMN Voltage Divider Networks.

Ratio Stability under Load: Change In Ratio, withVmax. (DC) applied to the Divider.

These Type HVD Voltage Dividers, with the same total resistance value (10 Meg, 20 Meg,and 50 Meg), can be manufactured with a custom R2 Resistance Value, to provide acustom Voltage Divider Ratio between 100:1 and 1,000:1.

At +85°C, Initial 1,000 hours, ratio change
0.020% max.
At +50°C, Initial 1,000 hours, ratio change
0.015% max.

Or, to optimize the cost of the device, a lower voltage rating, a reduced ratio tolerance of
0.10% or looser, a Ratio TC of 10ppm/°C or looser, and/or a reduced operating temperature range can be specified.

Shelf Stability: Ratio Stability less than 50 ppm/year

These specific devices will be assigned and marked with a unique Part Number
and are available with an MOQ of 1000 pieces.

Thermal Shock: Mil-Std-202. Method 107, Cond. A,except min. temp is -40°C, ratio change 0.02% max.
