TT Electronics products

Civil certified aerospace PSU providing multiple 28V supplies to the digital flight control system for use on a business passenger jet. Currently awaiting formal flight certification after a recently successful qualification campaign. We design, manufacture and test single and three-phase AC-DC power supplies for high reliability and harsh environment applications.

Currently in service and deployed across multiple nations on front line fighter jets, the DC-DC converter provides support to key DC loads during aircraft power-up voltage transients then channels aircraft DC power during flight. This product needs to be highly reliable as failure would otherwise result in mission cancellation. We design, manufacture and test custom high-density, DC-DC converters with power levels up to 4kW, efficiency up to 96%. Exceptional quality, wide input ranges. driving characteristics with low emissions.

AC-AC Conversion. Design Assurance to DO-254 DAL B. Forced Air Cooled. EMC to RTC/DO-160D. Enviromental to EUROCAE ED14, DO-160G, MIL-STD-810F, ABD0100.1.2. Power Quality to AMD-24C.

The HA19 common mode choke is designed specifically for noise suppression applications found in the growth and expansion of new generation vehicles such as electric vehicles (EVs) and plug-in hybrid vehicles (PHVs). The HA19 series offer high efficiency and excellent current handling in a rugged construction. It is mechanically robust and features low DC resistance and low temperature rise performance. HA19 is ideal for high efficiency electric power steering EMI applications where size and AEC-Q200 certification is critical.

The 2N2222AUA (TX - Obsolete, TXV - NRND) is a hermetically sealed ceramic surface mount general purpose switching transistor. The four pin ceramic package is ideal for designs where board space and device weight are important design considerations. The “UA” suffix denotes the 4 terminal leadless chip carrier package, type “A” per MIL-PRF-19500/255. Typical screening per MIL-PRF-19500/255. The burn-in condition is VCB = 30 V. PD = 400 mW, TA = 25° C, t = 80 hrs. Refer to MIL-PRF-19500/255 for complete requirements. In addition, the TX and TXV versions receive 100 % thermal response testing. When ordering parts without processing, do not use the TX or TXV suffix.

The OPF1414 series fiber optic transmitters contain a high speed 840 nm GaAIAs LED. This LED in conjunction with the package lensing is designed to efficiently couple light into multimode optical fibers ranging in size from 50/125 μm up to 200/230 μm. The high coupling efficiency of the LED and lensing allows the devices to be used at low current drive levels thus decreasing the power consumption and increasing system reliability. The consistency of coupling varies by less than 5 dB from part to part which reduces the dynamic range requirements of the receiver. The high power (-16.0 dBm into 50/125 μm) OPF1414 was designed for small fiber applications or where there are large fixed losses such as in systems that contain star couplers or in line connectors.

The Shunt Gapmeter Model LPCB is approved for regular monitoring and testing of sprinkler systems by the LPCB, Loss prevention Certification Board, under their ‘Rules for Automatic Sprinkler Installations’, in the UK, and by many equivalent organizations in other countries. Model LPCB provides a compact, robust, direct reading flowmeter for 50mm-200mm pipelines and is suitable for use in horizontal or vertical pipes.

A complete VA flowmeter consists of a glass flow tube and float scaled to the flow units required, and a frame to provide the end block supports and to cover and protect the tube. The NGX series frames use flow tubes with nominally 100mm long scales, whereas the smaller LGX frames use flow tubes with nominally 30mm scales. To choose a complete flowmeter select the frame code required, and separately specify the fluid flow range needed on the flow tube scale.

The OEM pressure sensor is a high performance, cost effective solution available in standard ranges from lOOmbar to 600bar. All ranges are available in gauge or absolute format. It is ideal for continuous use in applications where the pressure medium is wet and corrosive and long term stability is of prime importance.
