Working closely with customers’ design teams, TT electronics engineers have pioneered magnetic component designs that provide high frequency, high temperature, and high current performance, using a variety of core materials and package designs. Compact magnetic components with high current capability provide optimal power control for industrial electronic systems, portable computing and power electronics.
TT electronics has also developed rugged surface mount resistors specifically for surge/pulse applications and extreme thermal cycling – ensuring superior performance while providing significant cost savings
We have highlighted a selection of our key products that will help engineers designing for DC/DC, high-voltage, switched mode and uninterruptible power supplies.
Barrier discharge / bleed resistors
Common mode EMI filter chokes
TT electronics' extensive technical teams have a wealth of experience in building control and automation, working in partnership with OEMs world-wide.
The TT electronics portfolio includes products from resistors for metering, safety circuits and Residual Current Devices (RCDs), through infrared optoelectronic devices for sensing and switching, to magnetic devices for RCDs.
But it goes way beyond helping designers find the right products with the right specification. We work as close as possible with customers to improve device characterisation procedures: for example developing multiple pulse tests for resistors to reduce ageing and drift.
In integrated power stages as well as discrete resistors, fast customisation with TT electronics know-how is transforming custom products into highly competitive solutions for high-volume applications.

Drives & Controls
Drives & Controls
Motor and drive manufacturers are helping their customers meet challenges like the increasing cost of energy through developing increasingly precise and efficient control technologies. TT electronics is helping them deliver ever-improved performance in smaller, lighter packages.
One way we are achieving this is through advanced resistor technologies such as: thick film steel-mounted braking resistors, low inductance power resistors for compact motor drives, and current-sense resistors for control.
Precision control and management is provided by TT electronics' optoelectronic devices working in encoders and position sensing applications.

Moulded Power Inductors
TT electronics is addressing the needs for today’s space constrained, higher operating temperature circuits by introducing the latest iteration of the very successful HM72 moulded power inductor series.
The newly released versions: HA72E and HM72E; have been developed for use high operating temperature applications including
power supplies and DC/DC converters used in oil and gas down - hole exploration devices, power modules, power converters and simple switcher modules used for high density server and data storage cards. They can also serve as EMI filters and ripple current filters where those needs call out the highest current rated inductors in the smallest package.
The new versions make use of TT electronics’ innovative material development research to provide the highest saturation current levels per overall device volume. Additionally they deliver operating temperature limits up to 155 deg C with low core losses and no thermal aging issues all in a magnetically shielded package.
The HA72E series supports designers of industrial and automotive circuitry, where ruggedness is key and solid performance is a must by being AEC-Q200 certified.
MagnePot Rotary Position Sensor
TT electronics’ new MagnePot rotary position sensor is used in many and varied industrial applications including industrial joysticks, weather vanes and automation.
Designed to operate reliably in demanding conditions, the MagnePot series is available with sensing angles between 35° and 360°. Incorporating Hall effect non-contacting technology means they do not wear out, as in contacting devices, and there is no degradation of the output signal over life, making them ideal for applications where minimal maintenance is required.
The 6120 family features a bushing mount with a 7/8” diameter package and a minimum of 10 million shaft rotations. Special designs with sealed shafts and rear lids and coated electronics for protection from severe environments are also possible. A supply voltage of 5Vdc is required and the ratiometric output goes from 3% to 96% of the supply voltage.
The 6150 series offers the same electrical performance and features of the 6120 family, however the innovative servo mount package provides a rotation life of 100 million revolutions. Multiple output voltage options are also available and both families are operational from -40° to 125°C.
Resistors for Surge Protection
Surge energy ratings for the new wirewound WHS series are the industry’s highest from 2W to 7W, 1 to 330Ω.
TT electronics has introduced a comprehensive range of wirewound resistors offering the industry’s highest surge energy ratings from 2W to 7W sizes. Suitable for a wide range of pulse applications, the WHS series flameproof resistor is aimed, particularly, at designers of power supplies requiring a line input resistor for inrush limiting and protection.
Optimised surge performance derives from the special winding design of these resistors, in which a high-purity ceramic substrate is assembled with interference fit end-caps welded to the terminations. The resistive element is then wound on the substrate and welded to the caps. Its ability to withstand the high surge conditions associated with switch-on, discharge or external surge events results in improved reliability, savings in PCB space and reduced need for additional components.
The WHS2, rated at 2W, is the smallest resistor of its type on the market and provides surge energy ratings of 0.9 to 5.8J. Models are available rated 3, 5 and 7W, in resistance values up to 330Ω and taking energy ratings up to 60J. With a 10W model under development, the WHS family will offer better performance than competitors over a wider span of power and resistance. Moreover, designers have greater flexibility with the additional options of radial, goalpost, lancet and SMD Z-form leads.
All the new resistors benefit from UL94-V0 flameproof protection and operate over a wide -55o to +155°C temperature range.
Reflective Object Sensor
The OPB733TR reflective object sensor features high resolution and a wide detection range, and is supplied in a miniature package that is ideal for a variety of industrial applications including assembly line automation, card readers, counters and sorters, proximity sensing, machine safety, and electrical, gas and water meters.
The sensor has a typical peak emission wavelength of 890nm, mounted alongside a NPN silicon phototransistor, which responds to light reflected by the object being sensed. The device features an excellent detection range from 0.4" (10mm) to 1.0" (25.4mm). In addition, the minimum phototransistor output current of 100µA eliminates the need for external amplification of the output signal, which simplifies the drive circuitry.
The phototransistor output on-state collector current is 0.1mA (100µm) at 1/2" [12.7mm] distance from the target and a 20mA forward current and VCE of 5V. Rise and fall time for the phototransistor signal is typically 15µS.
The OPB733 ideal to be utilized in electricity meters in the remote-disconnect actuator or relay (sensing home position) and in gas and water meters to detect valve shut-off home and end-of-travel position.
