Stackpole Electronics has introduced a 2512 chip resistor engineering kit. KIT-RMCF2512FT-21 has 97 E24 series 1% resistors from 1Ω ohm to 10kΩ. There are 20 of each value, making a total of 1,940. Its RMCF2512 resistors are AEC-Q200 compliant, measure 6.3 x 3.2 x 0.55mm and can handle 1W at 70ºC. Temperature coefficient is ±400ppm/ºC for 1 – 9.76 types ...
Vishay has created a 5W 1206 current sense resistor range. Called WSLF1206, it is available in values down to 300μΩ. Only the 300μΩ and 500μΩ versions are rated at 5W, and that is only up to 70°C ambient temperature. This drops to 3W up to 100°C, and lower beyond that. 1, 2 and 3mΩ types complete the range, and they ...
Emis of Sweden has a range of three-phase passive harmonic filters intended to minimise harmonic distortion with non-linear loads such as variable frequency drives (VFDs), uninterruptable power supplies (UPS) and rectifiers. “They are typically tuned to specific harmonic orders – 3rd, 5th, 7th and 11th, for example – providing low-impedance paths at those frequencies to divert harmonic content,” according to ...
Mouser has signed a global distribution agreement with Quantic Evans, the high-energy density capacitor specialist for mission-critical applications. Quantic Evans’ hybrid capacitors, known as EVANSCAPS, serve diverse markets, including aerospace, energy and communications, where high-reliability, size, weight and power are crucial. “Partnering with Mouser significantly expands global access to our high-reliability capacitor technologies,” said Todd Oelerich, director of sales and ...
SiTime has added 0.46 x 0.46mm 0505 CSP resonators to its timing portfolio, with the Titan MEMS platform. They are based on SiTime’s sixth-generation MEMS technology, FujiMEMS and are “at least four times smaller than the smallest legacy quartz alternatives” said the company. The resonators are available either PCB-mounted for customer integration, or as bare die for co-packaging with SoCs ...
Kyocera AVX is once again stacking its ceramic capacitors to increase CV product in a small footprint, this time for high reliability applications. ‘DSCC 25007 Mini BME Stacks’ combine multiple 2220-size capacitors with X7R characteristics (from its MIL-PRF-32535 range) using a legged lead-frame, have base metal electrodes, and are 100% Group A tested. 100% Group A and Group B testing ...
TDK has unveiled through-hole aluminum electrolytic capacitors designed to work at up to +140°C for automotive power steering, fan control and transmission systems. They come in axial-lead (B41699) and soldering star (B41799, see photo) types, rated to 25 or 35V, with capacitance ranging from 1,800 to 13,000µF. These are branded as “ultra compact” by the company. Picking a mid-range example, 4,700μF types ...
TDK has created a SMD inductor particularly for the bias-tee (bias-T) circuits used to split RF signals and dc power from, or combine them onto, a single line. “The component achieves an inductance of 10μH despite a 1206 case size,” said the company. It has “high impedance over a frequency range of 10MHz to 200MHz”. Measuring 1.2 x 0.6 x ...
Rutronik is stocking precision thin-film surface-mount resistors from Vishay, for industrial, medical and automotive use – all are AEC-Q200 qualified, sulphur tested and RoHS compliant. TNPW e3 resistors are an “economical alternative in the thin-film range”, said the component distributor, “ideally suited for industrial and automotive use”. Size options are 0201, 0402, 0603, 0805, 1206 and 1210, tolerance can be ...
TDK has introduced surface-mount gate drive transformers that measure ~14 x 10 x 9mm and have basic isolation up to 1kVdc. “These components meet IEC 61558-1/2-16 for basic insulation and enable gate driver designs for full-bridge inverter modules, particularly in e-mobility and industrial environments,” said the company. “A good choice for fast-switching IGBT and SiC devices, the triple-insulated winding structure, ...
