The Resistor type
PBH
, which is very similar to type
TO 247 for high power transistors, features small
dimensions complemented with high load capacity and
compatibility with active components.
The use of the precision resistance material
MANGANIN
as well as optimization of conductor leads and resistance
structure result in a low temperature coefficient, a long-
term stability and low inductance.
The resistor is mounted through a center bore to the
heatsink, whereby the large area of the base plate will
function as an optimum heat transfer.The thermal resistance
between resistor layer and aluminum base plate is rated
below 4 K/W, so that the temperature of the resistor foil
Remarks:
- Standard resistance values according to E12 with the additionel values of 2 and 5
- Minimum quantity of other values on request
- Tolerance 0.5% for values of 10 mOhm up
will rise only little at a nominal load of 10 W, compared with
customary resistors. This again results that the absolute
resistance deviation caused by the temperature coefficient,
is very low under load and will serve for a good stability on
overloading.
The resistor is ideally suited for applications in power
electronic and control technique, as most applications at
inductive loading will require operation with switched power
regulating units.
Short connection distances and small dimensions with
high loading capacity and low inductance are a prerequisite
for obtaining high switching frequencies.
