TCXOs now with superior phase noise and g-sensitivity performance
Rakon has announced fully integrated RTX-A TCXOs are now available with a g- sensitivity option. The RTX-A ‘G’ uses Rakon’s patented RGX technology which enables the TCXO to perform with enhanced g-sensitivity performance in challenging environments.
The ‘G’ version includes all the other
features of the RTX7050A and RTX5032A including typical phase noise of -154 dBc / Hz at 100 kHz offset for a 50 MHz TCXO. The RTX-A series, employs an analogue IC for both the oscillator and temperature compensation. Frequencies are available from 5 to 52
MHz. Offering frequency stability down to ±0.1 ppm, the RTX-A series is available over a wide temperature range of -40°C to +85°C. According to the company power consumption as low as 2 mA is achievable.
The RTX-AG series is suitable for use in
microwave communications including ODUs and IDUs, as well as LTE femtocells and smallcells, IP timing and many other applications.

Vishay introduces slim polypropylene film capacitor for DC-Link applications
Vishay Intertechnology has announced a new high-performance metallized DC polypropylene film capacitor, engineered for DC-link applications, that features a slim design, the industry's broadest CV range from 2 µF up to 100 µF, and voltage ratings of 500 VDC, 700 VDC, and 1,000 VDC. Providing designers with a number of options for their specific application, the slim MKP1848S features low profiles of 12 mm, 15 mm, 18 mm, and 24 mm. With a long life of > 100,000 hours at nominal DC voltage and + 70 ºC, the MKP1848S is optimised for inverters, power supplies, solar micro-inverters, on-board chargers (EV/HEV), pumps, and LED drives. The DC-link capacitor features capacitance tolerance down to ± 5 %, low self- inductance of < 1 nH per mm of lead spacing, high peak current capabilities to 900 A, and high RMS current to 22 A. Offered in a flame-retardant
Syfer’s ProtectiCaps save on production stage
The latest innovation in multilayer chip capacitors (mlccs) from Syfer Technology is a range of compact devices suitable for high voltage applications, supplied with a built-in protective coating. Typically, with standard high voltage capacitors, a special coating is applied after the devices are soldered onto the board in order to minimise the risk of flashover from one termination on the chip to another. The ProtectiCap process applied to its high voltage range of mlccs has been developed specifically to address this issue. The integral coating, a matte tin layer over the nickel FlexiCap base termination, minimises the risk of flashover and avoids the need for the customer to apply conformal coating after soldering.
Aimed at applications such as power supplies, lighting ballasts, inverters/DC link, and general high voltage circuits, the X7R dielectric ProtectiCap range of mlccs combines high voltage capability with small package size. The capacitance range of devices in this series is 100pF to 33nF, package sizes range from 1206 to 2220, and voltages available include 2KV, 2.5KV, 3KV, 4KV and 5KV. Typical devices include a 2KV mlcc in 1206 package with capacitance range of 100pF to

3.3nF, 2KV mlcc in 2220 package with capacitance range of 220pF to 33nF, 3KV device in 1880 package with 100pF to 3.3nF capacitance range, and 5kV mlcc in 2220 package with 220pF to 4.7nF capacitance range. Additional specifications include operational temperature range of -55 to 125oC, temperature coefficient of capacitance typically at +/-15%, and insulation resistance of 100Gohms or 1000s, whichever is the least.
This range is fully compliant with the RoHS and WEEE directives and parts are compatible with lead free solders. The devices, manufactured at Syfer’s Norwich, UK facility, are available immediately in sample packs or on standard 6 week delivery for production volumes. Pricing, on application, depends on value and volume.
