INTRODUCTION
Vishay Foil Resistors 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.
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. Contact

Note
* This datasheet provides information about parts that are RoHS-compliant (with exemption) and/or parts that are non-RoHS-compliant.
For example, parts with lead (Pb) terminations are not RoHS compliant. Please see the information/tables in this datasheet for details.

Notes
(1)
For resistance ratios outside the range, contact our Applications Engineering Department.
(2)
The VHD200 is available in any required ratio between the resistance values of 100 Ω and 20 kΩ, such that R
1
can be any value
between 100 Ω and 20 kΩ and R
2
can 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

Note
To acquire a precision resistance value, the Bulk Metal
®
Foil
chip is trimmed by selectively removing built-in “shorting bars.”
To increase the resistance in known increments, marked
areas are cut, producing progressively smaller increases in
resistance. This method reduces the effect of “hot spots” and
improves the long-term stability of Bulk Metal
®
Foil resistors.
