TDK has introduced a series of high-value metal-framed multi-chip ceramic capacitors for automotive electric power trains, on-board chargers and wireless power transfer systems, where the capacitors must handle high currents or voltages, or have high capacity. “To meet these needs, TDK developed the CA series, the largest MLCCs in the industry [6 x 5.6 x 6.4mm] with a metal frame ...

TDK has introduced a low-power digital output mems microphone for voice command and sound detection in IoT applications such as smart watches and augmented reality glasses. Called T5848, it has a I2S interface and an ‘acoustic activity detect’ (AAD) function with its own outputs. Vital statistics of its surface-mount bottom acoustic port package are 3.5 x 2.65 x 0.98mm. Three traditional ...

TDK is aiming at automotive and industrial 360° magnetic angle sensing in high-reliability systems with a tunnel-magnetoresistance (TMR) IC. TAS8240 is designed to operate next to a rotating magnet and contains four pairs of TMR half bridges (four Wheatstone bridges) to provide four separated sine-cosine outputs. “Depending on system architectures, fail-operational concepts can be supported by the new sensor,” according ...

TDK claims to have developed a solid-state battery that can hold 1,000Wh/litre, as a replacement for coin cells. “Utilising proprietary material technology, TDK has managed to develop a material for the new solid-state battery with a significantly higher energy density than TDK’s conventional mass-produced CeraCharge solid-state batteries, due to the use of oxide-based solid electrolyte and lithium alloy anodes,” according ...

TDK has put an mems piezoelectric ultrasonic time-of-flight distance sensor inside a 3.5 x 3.5mm package along with its signal chain. “ICU-10201 offers the sensitivity required for obstacle avoidance or proximity sensing, which is used frequently in robotics, drones and robot vacuum cleaners,” according to the company. “The sensor provides millimeter-accurate range measurements to targets at distances up to 1.7m, ...

TDK has announced automotive smart motor drivers that can handle 4 x 1A peak current and include an Arm Cortex-M3 processor core. HVC 5222D with 32kbyte of flash and HVC 5422D with 64kbyte can drive brushless dc, brushed dc (2A) and stepper motors. They also have 4kbyte ram, 2kbyte of emulated eeprom and 1kbyte of non-volatile registers, and are “SEooC ...

IAM-20685 is the smallest ASIL-B-compliant monolithic 6-axis MEMS inertial measurement unit in production, according to TDK, and it was developed in compliance with ISO 26262 for automated vehicle parking, for example. It “enables parking-assistance systems to determine the vehicle’s motion and vision systems to enable stabilisation techniques and improve image quality, and for positioning systems to enhance absolute position accuracy,” ...

TDK has introduced six models to its 7.5kW ‘Genesys+’ series of 7.5kW programmable dc power supplies. The new values of 0-30V (250A), 0-60V (125A), 0-80V (94A), 0-200V (37.5A), 0-300V (25A) and 0-1000V (7.5A) slot in between earlier models in the series, introduced in July (see this article for more details). The units need three-phase ac power and there are versions ...

TDK has introduced quarter brick isolated 50W dc-dc converters with a 12:1 input range: 14 to 160Vdc There are also similar 75W converters, this time with a 9-75Vdc (8:1) input range, Quarter brick converters (left hand in image), with smaller 20W parts as well as larger 200W parts in the pipeline (see below).  Called PYQ50, there are three 50W quarter ...

TDK has created two series of capacitors specifically for power factor correction (PFC). Jointly-branded PhaseCap Energy Plus, the series are: B25674C – gas-impregnated, 230 to 690Vac, 5 to 33.1kvar compensation B25675C – biodegradable resin impregnated, 230 to 1,000Vac, up to 60kvar compensation Lifetime is up to 240,000 hours in temperature class -40/D, the terminals are class IP20 touch-proof, and ceramic-based discharge resistors ...
