Resistors
TT Electronics plc is a global electronics company.
Within its resistors business unit are multiple manufacturing facilities and
dedicated engineering teams providing custom solutions.
BI Technologies, IRC and Welwyn are market leading brands within this group, with a 70-year track record of resistive
component innovation.
TT Electronics offers the full spectrum of resistor technologies and a broad standard product range, in addition to providing
custom engineered solutions.
Medical Application
A manufacturer of portable automatic external defibrillators (AEDs)
needed a compact high voltage resistor for use in the charge regulation
circuit. Standard products from other sources were proving unreliable under
conditions of sustained high humidity and high voltage loading. The precision
and stability with time and temperature were critical as they directly impact
the tight error budget for delivered energy dosage. TT Electronics engineers
solved this problem with a planar resistor with optimised thick-film element
design and a high integrity epoxy coating and supported the customer
through their rigorous approval process.
Other innovations in this area include pulse withstanding chip resistors
for monitor circuit protection and a 200J energy dump resistor based on
reinforced wirewound technology to enable daily self-test diagnostic cycles.
Aerospace Application
A designer working on an anti-ice aircraft surface heating system had
to meet stringent safety requirements in the event of failure of a heating
circuit. The failure mode to be mitigated was an “always on” condition, and
this called for a single shot disconnection switch. TT Electronics engineers
were contacted to help identify a solution, but nothing was available off the
shelf. A set of potential solutions was proposed and the preferred option was
a combination of self-switching resistive heater and thermal fuse. This was
developed from concept into a fully qualified component within the required
timescale. The compact format of the design also contributed significantly
to the customer’s mass reduction target.
Consumer Application
Safety is becoming increasingly important in consumer products and a key
aspect is protection against fire by the use of fusing line input resistors. With
one component it is possible to reduce inrush current, protect against power
line surges and give flameproof circuit opening under fault conditions. One
company working in this area had a further need for fusing to be inaudible
and invisible to the consumer.
TT Electronics devised a solution using a wirewound resistor with impact
absorbing coating which contains the fused element without fragmenting.
Other innovations include the offer of UL1412 recognised fusing resistors.
Resistors
Industrial Application
High-end industrial circuit breakers need to give reliable long-term
performance under harsh conditions. In particular, transient surges caused
by switching of inductive loads present a challenge. When a designer of
industrial circuit breakers needed to modernise a design to SMT format, a
through-hole wirewound protection resistor was proving hard to replace
without filling a very large area with chip resistors. TT Electronics developed
a solution whereby an axial part is leadformed and packed in blister tape.
The resulting “ZI-form” component can be picked, placed and reflowed as an
SMT part.

The temperature which would be adopted by the body
of the resistor under application conditions except with
negligible power dissipation in the resistor.
The resistance value at which application of the LEV
causes dissipation of the full rated power.
The maximum continuous voltage which may be applied between the resistor and a conductor in contact
with its insulated body.
The maximum continuous voltage which may be applied across a resistor whose ohmic value is greater than
the critical resistance.
Power dissipation which exceeds the power rating for
durations exceeding 0.1s.
The maximum continuous power that may be dissipated by a resistor whose ohmic value is less than the
critical resistance and at a defined maximum ambient
temperature.
Power dissipation which exceeds the power rating for
durations less than 0.1s.
A set of components with the same basic design
features and performance and usually a range of sizes
and ratings.
Temperature Coefficient of Resistance; the maximum
magnitude of reversible ohmic value change per degree
centigrade due to deviation in body temperature from a
reference normally of 20°C.
The maximum allowable magnitude of deviation from
nominal ohmic value measured at delivery and at room
temperature.
An individual member of a series with specified size and
rating.
Voltage Coefficient of Resistance; the maximum reversible reduction in ohmic value per volt due to an increase
in applied voltage.
