Coax connectors run up to 50GHz
Covering a frequency range from DC to 50GHz, embracing over 30 different series and comprising hundreds of versions, Amphenol's coaxial connectors are available from TTI.

TTI has an inexpensive surface-mount sounder from Murata.
Designated the A700 Series, the AO-CAP available from TTI marks capacitor manufacturer Kemet's entrance into the aluminium capacitor market.
The product offers the benefits of extremely low ESR afforded by aluminium, true surface mount capability through the use of a polymer cathode material, and high capacitance retention at high frequencies.
Offering many advantages over wet electrolytic capacitors, the AO-CAP structure uses aluminium as the anode material, aluminium oxide as the dielectric and a conductive, organic polymer for its counter-electrode material.
The A700 series features a moulded case with wrap around terminations that provide strong protection against cracks.
This makes the capacitor an ideal alternative to high capacitance ceramics and the existing aluminium organic capacitors found in the industry.
The structure of the AO-CAP provides many advantages, including a true surface-mount capability that is robust to the SMT process, no dry-out related failure mechanism, and no voltage derating up to +125C.
The AO-CAP is a totally lead free device with excellent surge current performance and long term reliability.
The operating temperature is a wide -55 to +125C.
For familiarity and ease of integration, AO-CAP is offered in the same EIA industry standard case sizes and packaging formats as Kemet's tantalum chip capacitor lines.
TTI is able to quickly provide AO-CAP information and product samples to customers who need the technological advances of the low ESR polymer aluminium AO-CAP in their designs.
As a further aid to designers, Kemet's Spice simulation software models the frequency behaviour of ceramic, tantalum and aluminium surface mount capacitors, and can be used to determine the appropriate Kemet capacitor for a given application.
