Würth Elektronik has combined Classic and LE version 5.4 in a single Bluetooth module measuring 16.6 x 12 x 1.7mm including its antenna. Called Skoll-I, “the module is already certified for conformity in all major target markets”, said Wurth. The “module offers an opportunity for developing devices that need to connect to both legacy and modern devices. [It] also offers ...
A spirometer need not be a large and expensive device, says Gerhard Stelzer, outlining the design for a mobile version for tests at home. Patients with breathing difficulties can take a lung function test, using a spirometer. The device measures the amount and speed of air that is inhaled into and exhaled from the lungs to assess respiratory volumes and ...
Würth Elektronik Circuit Board Technology has finalised plans to close its Schopfheim PCB production site in Switzerland, first announced in October. “The management and works council have now reached an agreement on a reconciliation of interests and a social plan, which was presented to the affected employees at a works meeting on Thursday, February 6, 2025,” according to the company. ...
Wurth is offering vibration-resistant versions of its surface-mount aluminium electrolytics and aluminium hybrid polymer capacitors. “SMT components are often not the best choice because, without special adaptations, they may not withstand the prolonged vibration stress,” said the company .” However, making electronics vibration-resistant does not necessarily require special connection techniques like press-fitting. Thanks to their enlarged solder pads and thicker ...
Würth Elektronik has created a range of opto-isilated triacs for controlling light AC loads and larger triacs. They are called WL-OCTR, and come in a choice of packages: through hole DIP-4 or DIP-6, or surface-mount SOP-4. Through-hole parts offer 5kV breakdown between input and output, which drops to 3.75kC for surface mount. DIP parts can also be supplied with legs ...
Würth Elektronik has shrunk a humidity sensor into a 1.5 x 1.5 x 0.5mm 5pad DFN package. Called 2525020210002, it works over 0 – 100% relative humidity, typically to within ±1.8%RH (±3.5%RHmax) over 20 – 80%. Also in the device is a -40 to +125°C temperature sensor, accurate to ±0.2°C across 0 to 60°C, and ±0.6°C over its full range. ...
Würth Elektronik adds dc ripple bias modelling to its RedExpert on-line power analysis tool. “It is a well-established but little understood fact that ac core losses increase when the ac ripple is dc biased – normal intuition says that dc bias does not increase ac cores losses because it is a static shift,” it said. It is a situation found ...
Würth Elektronik has introduced two families of surface-mount multi-channel galvanic isolators for digital signals. Devices in the WPME-CDIP family have four 100Mbit/s isolated channels and a built-in dc-dc converter that provides isolated power from one side to the other. Different versions have different combinations of digital isolator directions: all from input to output, three in that direction and one returning, ...
