Low-Voltage Single-Line Protection Devices Protect 3.3, 5 and 12V Systems
Semtech Corp has announced three new, single-line versions of its uClamp protection products designed for portable devices with low voltage levels, starting at 3.3V. The uClamp3301P is designed to protect 3.3V lines, the uClamp0501P is designed to protect 5V lines, and the uClamp1201P is designed to protect 12V lines.
Tiny microwave capacitor delivers the lowest equivalent series resistance in an 0805 case
AVX has just introduced its SQCF microwave capacitor that delivers the lowest Equivalent Series Resistance (ESR) in a 0805 case size on the market. SQCF microwave capacitors present an ESR down to 50mOhms at 1GHz and a quality factor (Q) greater than 10,000 at 1MHz. Devices deliver high performance and reliability for base station infrastructure requiring high Q and power handling capability.
Self-Hold Thermal Cut-Outs
PEPI’s JS series thermal cut-outs combine the benefits of both automatic and manual reset cut-outs, without the disadvantages of either. By incorporating an internal resistor, the self-holding PEPI JS is the same size as the auto-resetting PEPI J, but with a manual-reset function.
