Inductors: Compact dual inductors with high saturation current
TDK Corporation has extended its range of dual inductors to include the new EPCOS series B82477D6*. The seven series types cover an inductance range from 2 x 3.9 µH to 2 x 47 µH and are designed for maximum rated currents from 2.83 A to 7.05 A. A special feature of the inductors, which are certified according to AEC-Q200 and compatible with RoHS, are the high saturation currents of up to 16.1 A.

The magnetically shielded inductors have dimensions of just 12.5 x 12.5 x 10.5 mm3 and are designed for a wide temperature range of -55°C to +150 °C. Depending on the type, the inductors offer very high coupling factors of the two windings from 97 to 99 per cent.

The fields of application of dual inductors are diverse: Indeed, they can be used as coupled inductors in SEPIC (Single-Ended Primary Inductance Converter) or 1:1 transformers in flyback topologies. A further application involves use as a common-mode inductor in power supply lines. The isolation voltage between the two windings is >500 V.

Main fields of application
  • Common-mode inductors in power supply lines
  • DC/DC converters in SEPIC topology
  • Flyback converters
Main features and benefits
  • High saturation currents of up to 16.1 A
  • Low dimensions of just 12.5 x 12.5 x 10.5 mm3
  • Wide temperature range of -55°C to +150°C
  • High coupling factor of up to 99 per cent

TDK announces new 3-axis accelerometer, finalizing transition of SmartAutomotive™ non-safety product family to 105°C

TDK introduces 3D HAL® technology-based position sensor with analog output and SENT interface

TDK offers mechanically decoupled ultrasonic modules for collision avoidance
TDK Corporation presents the ultrasonic sensor module USSM1.0 PLUS-FS, in which the sensor element is mechanically decoupled from the housing. This makes the IP65/67 protected sensor with the order number B59110W2111W032 immune to external mechanical vibrations that can falsify the measurement result. The module, which is supplied with a nominal voltage of 12 V, can be mounted in a front chassis via a M19 thread with a locking nut or via snap hooks.

TDK offers compact high-current chokes for automotive and industrial applications
TDK Corporation presents the B82559A*A033 series of new shielded EPCOS ERU33 high-current chokes for through-hole mounting. Designed for very high saturation currents from 32 A to 83 A at 100 °C, the six new types cover a range of inductance values from 3.2 µH to 10 µH.

EMC Components: TDK develops industry’s first high-reliability chip beads for automotive
TDK Corporation announced the development and mass production of the MMZ1608-HE series of high-reliability chip beads for automotive use, compatible with high-durability solder in 150 ℃ environments.

Surge protection: Failsafe chip varistors for automotive battery lines
TDK Corporation presents a new range of Open Mode chip varistors for electronic automotive assemblies that are directly connected to the battery. The new chip varistors offer reliable protection against transient surge voltages according to ISO 7637-2, and meet the failsafe requirements according to the VW standard VW 80808. Even when subject to excessive bending stress, short-circuits are avoided, which is particularly important for unswitched battery terminals (e.g. terminal 30).

Inductors: Compact dual inductors with high saturation current
TDK Corporation has extended its range of dual inductors to include the new EPCOS series B82477D6*. The seven series types cover an inductance range from 2 x 3.9 µH to 2 x 47 µH and are designed for maximum rated currents from 2.83 A to 7.05 A. A special feature of the inductors, which are certified according to AEC-Q200 and compatible with RoHS, are the high saturation currents of up to 16.1 A.

Aluminum electrolytic capacitors: Compact design with high ripple current capability
TDK Corporation (TSE:6762) presents the new B43707* and B43727* series of EPCOS aluminum electrolytic capacitors with screw terminals. They are designed for rated voltages of between 400 V DC and 450 V DC and cover a capacitance range from 1800 µF to 18,000 µF.

TDK announces world’s first MIPI standard SoundWire® microphone
TDK Corporation (TSE: 6762) introduces the world’s first MIPI Standard SoundWire® microphone for mobile, IoT and other consumer devices. This multimode microphone pushes the boundaries of digital microphone acoustic performance while providing advanced feature sets with very low power.
