Digiseq and Infineon launch world-first pre-certified ring inlay
Digiseq has received Mastercard certification for a world-first pre-certified concentric ring inlay, opening up the market for small independents and large brands to quickly and effectively launch payment rings within their collections. The inclusion of the ring inlay with integrated secured NFC chip can deliver multiple services, opening new use cases in addition to payments, such as loyalty, access, events and hospitality for consumers’ everyday life.
Noise suppression filters support wide frequency bandpass for audio quality
Support for wide frequency bandpass, extending from the FM band to the cellular band, makes the MAF1005FR compact noise suppression filters particularly well-suited for devices where high sound quality is crucial. TDK explained this is because they control sound distortions with only minimal reductions in volume, thanks to their low resistance.
They exhibit impedance of up to 2600 Ohm at 900MHz and insertion loss of more than 25dB. They also have a wide operating temperature range of -55 to +125 degrees C.
The MAF1005FR compact noise suppression filters measure 1.0 x 0.5 x 0.5mm. These multi-layer chip components are designed to improve sound quality and reduce noise interference in the audio lines (sound lines) of smartphones and other devices such as tablets, wearables, and portable games.
The audio lines in smartphones and similar devices emit electromagnetic noise, which can interfere with built-in antennas and degrade reception quality. This noise can be problematic, especially when high-quality audio and effective noise suppression are required. Chip beads are commonly used to control noise in audio lines. Although they effectively reduce noise, they can also distort the audio quality, impacting the sound in these lines, pointed out TDK.
The new MAF1005FR series of noise suppression filters can improve sound quality and reduce noise interference, with a typical impedance of up to 2600 Ohm at 900MHz and insertion loss of more than 25dB. This is achieved by newly developed low-distortion ferrite materials. As a result, the sound quality is maintained, and the issue of sound deterioration caused by chip beads is addressed.
The filters have a wide frequency bandpass, extending from the FM band to the cellular band. Unlike conventional products, which require two noise suppression filters for each frequency range, only one MAF1005FR component is required. This simplifies the design and implementation of noise suppression in electronic devices. The noise suppression filters support an operating temperature range of -55 to +125 degrees C.
TDK plans to expand its product lineup to include smaller components for high frequency bandpass noise control, ranging from 900MHz to 5GHz.
The filters are in mass production now.
TDK was established in 1935 to commercialise ferrite, a key material in electronic and magnetic products. TDK‘s comprehensive portfolio features passive components such as ceramic, aluminium electrolytic and film capacitors, as well as magnetics, high-frequency and piezo and protection devices.
The product spectrum also includes sensors and sensor systems such as temperature and pressure, magnetic and MEMS sensors. In addition, TDK provides power supplies and energy devices and magnetic heads marketed under the product brands TDK, Epcos, InvenSense, Micronas, Tronics and TDK-Lambda.
TDK has a network of design and manufacturing locations and sales offices in Asia, Europe, and in North and South America.
Silicon capacitors are smallest in the industry, says Rohm
Claimed to achieve the industry’s smallest size in a mass-produced surface mount package, the BTD1RVFL are silicon capacitors from Rohm for use in smartphones and wearable devices.
Smartphones and other devices with growing functionality require smaller components that support high-density mounting, explained the compay. Silicon capacitors using thin film semiconductor technology can provide higher capacitance in a thinner form factor than existing multilayer ceramic capacitors (MLCCs). They also have stable temperature characteristics and high levels of reliability.
These latest silicon capacitors are manufactured using proprietary RASMID miniaturisation technology which allows processing in one micron increments that eliminates chipping during external formation and improves dimensional tolerances within ±10 micron. This small variation in product size enables mounting with a narrower distance between adjacent components. At the same time, the rear electrode used for bonding to the substrate has been expanded to the periphery of the package to improve mounting strength.
The first products in the series to be released are the BTD1RVFL102 (1000pF) and BTD1RVFL471 (470pF). They are in 01005-size (0.1 x 0.05inch) and 0402-size (0.4mm x 0.2mm) packages. The surface mount silicon capacitors’ mounting area is reduced by approximately 55 per cent cent over general 0201-size (0.2 x 0.1inch) / 0603-size (0.6 x 0.3mm) products to just 0.08mm2.
A built-in TVS protection element ensures high ESD resistance that minimises the number of person-hours required for surge countermeasures and other circuit design elements, added Rohm.
A second series is planned for release in 2024 featuring superior high frequency characteristics and targeting high speed, large capacity communications equipment.
The capacitors are available from online distributors DigiKey and Mouser.
Rohm Semiconductor develops and manufactures a very large product range from SiC adiodes and MOSFETs, analogue ICs such as gate drivers and power management ICs to power transistors and diodes to passive components.
Production takes place in Rohm’s manufacturing plants in Japan, Germany, Korea, Malaysia, Thailand, the Philippines, and China.
Rohm Semiconductor Europe has its head office near Dusseldorf in Germany, serving the Europe, Middle East, and Africa.
