The four-terminal resistor type PBV derived from type PBH
is especially designed for the low impedance range, in
order to obtain lowest temperature coefficient values, and
in order to guarantee the independence of the resistance
value from the soldering quality. The use of the precision
resistance material MANGANIN combined with a highly
temperature resistant and humidity insusceptible Duroplast
cover as well as optimization of layout and lines result in a
high longterm stability, low temperature coefficient and low
inductance.
The shape is compatible with the latest power transistors.
The resistor is mounted through a center bore or
P / P Nenn
1
spring clamp to a heatsink, whereby the large area of the
base plate will provide excellent heat transfer. The low
thermal resistance between resistor foil and aluminum
base plate warrants for a low temperature rise at nominal
load in this configuration and permits transient overloading
up to one magnitude.
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 at high
load capacity and low inductance are a prerequi-
site to obtain high switching frequencies.
