Pretoria, South Africa – TRX Electronics has published comprehensive technical resources addressing critical component selection challenges faced by South African engineers working in telecommunications, industrial power control, and multi-board system design.
The electronic component distributor’s latest technical articles provide detailed comparisons and selection criteria for three essential component categories: RF interconnects, thyristors, and backplane connectors. These resources help engineers navigate manufacturer portfolio changes, power control specifications, and system architecture decisions that impact project timelines and system performance.
Understanding RF Interconnect Market Consolidation
The article RF Interconnects Market: How Major Manufacturers Are Expanding Their Product Lines examines how strategic acquisitions by Amphenol, TE Connectivity, and Molex are reshaping access to RF interconnects and coaxial connectors.
The guide explores Amphenol’s acquisition of CommScope and Carlisle Interconnect Technologies, which brought telecommunications infrastructure and aerospace connector expertise into their portfolio. Molex’s acquisition of AirBorn expanded their presence in military and aerospace connector markets, whilst TE Connectivity’s integration of ERNI Group AG strengthened their high-speed and fine-pitch connector capabilities.
These manufacturer consolidations affect product availability and part number transitions, creating challenges for engineers specifying components for telecommunications infrastructure, aerospace applications, and wireless systems. The resource helps engineers source connectors from Amphenol RF, Amphenol/SV Microwave, HUBER+SUHNER, and TE Connectivity through established distribution channels whilst managing evolving product lines.
Selecting Thyristors for Power Control Applications
For power control applications, TRX Electronics published Comparing Thyristors: A Comprehensive Selection Guide for Industrial Applications. This technical resource compares Silicon-Controlled Rectifiers, Gate Turn-Off thyristors, TRIACs, and thyristor modules from Littelfuse, Vishay Semiconductors, STMicroelectronics, and Bourns.
The guide examines specific devices including the Littelfuse SJ6040N2RP with 600V peak off-state voltage and 40A RMS current rating, and the Vishay VS-40TPS12LHM3 featuring 1200V peak off-state voltage with 35A average current capacity. These components serve motor drives, power conversion systems, and industrial automation equipment where reliable switching performance determines operational uptime.
Critical selection parameters detailed in the guide include voltage ratings such as Peak Repetitive Forward Voltage and Peak Repetitive Reverse Voltage, current ratings including Average On-State Current and Surge Current capacity, and dynamic ratings like Critical Rate of Rise of Off-State Voltage. The resource explains how these specifications impact thyristor selection for applications ranging from motor control to HVDC transmission systems.
Comparing Backplane Connector Architectures
The third resource, Comparing Backplane Connectors: VME, CompactPCI, and VPX, provides technical comparisons across form factors from TE Connectivity, Amphenol, ITT Cannon, Molex, and Harting.
The article examines how VME connectors utilise DIN 41612 standards with 96 or 160 pin configurations for industrial and military applications, whilst CompactPCI connectors adapt PCI bus technology to industrial form factors with hot-swapping capabilities. VPX architecture supports modern serial protocols including PCI Express and 10 Gigabit Ethernet for high-performance applications.
Pin count specifications, pitch considerations ranging from 2.54mm to 1.27mm, contact materials including phosphor bronze and beryllium copper, and plating options affect backplane connector performance in telecommunications, aerospace, and industrial control systems. The guide addresses high-speed signal integrity requirements for applications operating beyond 25 Gbps, where controlled impedance and stub length management prove critical.
