VHD200, VHD144

Vishay Foil Resistors

Bulk Metal^®Foil Hermetically sealed, Small Package,

Voltage Dividers with TCR Tracking of 0.1 ppm/°C

and Tolerance Match down to 0.001 %

FEATURES

• Temperature coefficient of resistance (TCR):

Absolute: 2 ppm/°C typical

(- 55 °C to + 125 C, 25 °C ref.)

Tracking: 0.1 ppm/°C typical

Pb-free

Available

RoHS*

COMPLIANT

• Tolerance:

absolute to 0.005 %

match to 0.001 %

• Power rating: VHD144 0.2 W at 70 °C (see table 1)

VHD200 0.1 W at 70 °C (see table 1)

• Ratio stability: < 0.001 % (10 ppm) 0.2 W at 70 °C for 2000 h

• Electrostatic discharge (ESD) above 25 000 V

• Non inductive, non capacitive design

• Rise time: 1 ns without ringing

Any value at any ratio available within resistance range

Vishay Models VHD200 and VHD144 are hermetic versions

of the molded divider 300144. The difference between them

is that the VHD144 has the full power rating of the 300144

while the VHD200 has a reduced power rating in exchange

for a full spectrum of values without the time delay for new

artwork (for values not yet tooled) and without NRE charges.

Further, the VHD200 is oil filled, providing additional

moisture protection and allowing considerable improvement

in ratio match and TCR tracking.

• Current noise: < - 40 dB

• Thermal EMF: 0.05 µV/°C typical

• Voltage coefficient: < 0.1 ppm/V

• Non inductive: 0.08 µH

• Non hot spot design

• Terminal finishes available: lead (Pb)-free

tin/lead alloy

The value of the hermetic enclosure over the molded part is

in the long term performance. Moisture and oxygen both

pass through plastic and both contribute to long term

degradation of resistive elements. Divider ratios of 1:1 are

not as likely to lose ratio with time but as the ratios become

greater, the imbalance of power has more effect on the ratio

stability and the hermetic enclosure becomes of paramount

importance.

Our Application Engineering Department is available to

advise and make recommendations. For non-standard

technical requirements and special applications. Please

• Any value available within resistance range (e.g. 1K234)

• Prototype samples available from 48 h. For more

2. The VHD200 is available in any required ratio between the

resistance values of 100 Ω and 20 kΩ, such that R₁can be any

value between 100 Ω and 20 kΩ and R₂can also be any value

between 100 Ω and 20 kΩ.

3. Power is proportional to the divider ratio.

Example: In a VHD144 (1K/10K dual), the power rating would be

18 mW on the 1K and 182 mW on the 10K, for a total of 200 mW

on R₁+ R₂.

4. For power rating of values below 10K, contact the applications

engineering department.

5. Any value from 100 Ω to 20 kΩ inclusive is available with some

derating of power.

6. Maximum voltage is 200 V.

* Pb containing terminations are not RoHS compliant, exemptions may apply
