Coilcraft’s surface-mount common-mode chokes include 16 sizes for power line circuits up to 10A, suppressing noise up to 100MHz with >40dB attenuation in some cases. Consumer electronics and industrial applications are foreseen. “All EMI chokes feature a low-profile, toroidal construction in a surface-mount, magnetically-shielded package with footprints as small as 13 x 13 mm,” said the firm. “They provide 1,000/1,500Vrms ...
Sometimes the simplest ideas at the best, and this surface-mount test probe pint from French form Nicomatic is certainly simple. Called the C12000 series, they are intended to present a mechanical test hook interface on an SMD PCB to allow an operator to clip on a test probe to the PCB, from an oscilloscope, for example. The size is 2.5 ...
Passive components from Yageo are now available from RS Components, following the signing of a global franchise agreement. The portfolio of chip resistors includes general-purpose thick-film components and thin-film high-precision high-stability resistors, automotive-grade components, current sensing devices, resistor array networks, high-voltage and surge resistors, RF attenuators and sulphur-resistant devices. Yageo supplies commodity and speciality versions of resistors, capacitors and wireless components for industrial, alternative ...
Panasonic has introduced a Power Choke Coil with high resistance to heat and vibration in addition to support for large current. Thanks to the use of ferrous alloy magnetic material, the ETQP5M2R5YSK provides inductance stability even at high bias current input and over a broad temperature range up to 150°C. The Power Choke Coil is AEC-Q200 qualified and features a low ...
TT Electronics has introduced a surface-mount component designed exclusively to get heat out of tight spots. Looking much like a chip resistor or capacitor, TJC series ‘thermal jumper chips’ are made of solid aluminium nitride for good thermal conductivity, with low electrical leakage and low capacitance. “Aluminium nitride has nearly five times the thermal conductivity of alumina,” said TT (AlN=~170W/m°C). ...
Surface-mount, multilayer varistors from TDK Epcos are now available from TTI. The CeraDiode and CTVS multilayer varistors (MLVs) are designed for smart home applications and security devices. According to the company, the MLVs’ surge current ratings are comparable to those of disk varistors, making them suitable for use as alternatives to transient voltage suppression (TVS) diodes, yet with a compact package that enables smaller ...
Trackwise of Tewkesbury is claiming a world record – for creating what is believed to be the world’s longest multi-layer flexible printed circuit (FPC), which will span 26m (85 feet) within the wings of an unmanned aerial vehicle to distribute power and control signals. It is a solar-powered plane, and the flexi is claimed to save ~60% of mass compared ...
Taiyo Yuden to offer 'lithium ion capacitors'. Operation is over -25 to 85℃
Vishay is aiming at the automotive market with AEC-Q200 qualified inductors in a 2020 case only 2mm high. Called IHLP-2020BZ-5A, all the parts in the range can be used at up to +155°C, making them suitable for under bonnet/hood operation. Construction and materials are optimised for dc-dc converter use up to 2MHz. “It also provides excellent attenuation of noise in high current ...
Johanson Dielectrics is offering a range of novel multi-layer ceramic devices that combines two balanced shunt capacitors with mutual inductance cancellation, and a certain amount of shielding.
