STMicroelectronics has released nine chip-scale passive RF balun ICs that include antenna impedance-matching and harmonic filtering for its STM32WL sub0GHz wireless microcontrollers. Intended to sit in Rx and TX paths between the MCUs and their antennas, the 8bump parts are in 2.13 x 1.83mm packages with a maximum height of 630µm after reflow. Applications are foreseen in LoRaWAN, Sigfox, M-Bus ...

Kyocera has announced NP0 dielectric MLCCs (multi-layer ceramic capacitors) approved to the Defense Logistics Agency Qualified Products Database (DLA QPD) for high-reliability military applications. “The new MIL-PRF-32535 BME NP0 MLCCs have higher CV capabilities than standard surface-mount PME MLCCs qualified to military and aerospace specifications and are currently available in M and T reliability levels and 0402, 0603, and 0805 ...

Kyocera has introduced AEC-Q200 qualified supercapacitors for automotive use. To be found in the company’s SCC series, there are four capacitors (diameter x length): 35F 3V SCCU30E356SRBQ (16  x 30mm) 50F 3V SCCV40E506SRBQ (18 x 40mm ) 100F 2.7V SCCV60B107SRBQ (18 x 60mm) 100F 3V SCCV60E107SRBQ (18 x 60mm) where the final Q indicates AEC-Q200 qualification “They can be used ...

Winner Snaptron – SG-Series domes Highly commended: STMicroelectronics for ISM330IS – iNEMO   The SG-Series are standard four-leg metal dome switches with two solderable tabs. They are designed to be integrated in existing SMT systems as an alternative to tactile switches. For the judges, this product has the potential for far-reaching applications, offering clear advantages.   Shortlist * Harting – ...

Cornell Dubilier is addressing higher voltage and higher capacitance applications with extensions to its XMPL polymer chip capacitor series, which all measure 7.3 x 4.3 x 1.9mm (EIA ‘7343’). “With low ESR and robust ripple current ratings, they will outperform surface mount electrolytics of greater size,” claimed the company. They “also provide longer life, greater stability with temperature changes, and ...

Kyocera AVX has announced small multilayer varistors (MLVs) that meet IEEE 100BASE-T1 and 1000BASE-T1 requirements. Available in 0402 and 0603 (0.5 ±0.1mm and 0.80 ±0.15mm respectively), they are rated for working voltages between 18 and 70Vdc, capacitance from 1.5 to 4.7pF, transients from 0.02 to 0.04J, peaks of 1 to 3A and operation across -55°C to +150°C. Actual working voltage ...

Stackpole has announced automotive-grade high-reliability chip resistors aimed at applications with pulse handling requirements. “Typically, the manufacturing process for thick film chip resistors allows for variation in the calibration trim, leading to variation in pulse handling performance,” according to the company, whose “RPCA series addresses these needs, providing reliable and repeatable pulse handling behaviour.” The key is having no calibration ...

Harting is offering printed circuit tracks on injection-moulded thermoplastic 3d objects, calling the process ‘3D-Mid’. The injection moulded part is custom-designed to fit between or around what ever the customer wants it to. The moulded part is doped with chemicals so that, after moulding, its surface is activated wherever conductive tracks are required  “through laser-direct structuring, a procedure created by ...

With rising automotive battery voltages, Coilcraft has identified a need for PCB-mount inductors to handle the full potential difference, and responded with an 800V rated family of physically-small unshielded through-hole ferrite drum parts. Qualified to AEC-Q200 Grade 3 (-40 to +85°C) and called the RFC0807BV series, they are 8.8mm in diameter, 7.5mm tall and have radial lead length options between ...

Stackpole has extended its CSRF2817 range of surface-mount foil-on-ceramic resistors up to 100mΩ – it continues to reach down to 3mΩ. “For devices that need somewhat higher resistance values, high current handling, low temperature coefficient and high stability, finding cost effective solutions can be challenging,” according to the company. “Film type resistors will not have high current handling, and all ...
