TDK , marca de calidad de la que somos distribuidores en Dachs S.A, amplía el catálogo de chokes dobles para muy altas frecuencias con su nueva serie B82791H2*N010

Inductors: TDK offers extremely compact current-compensated ring core double chokes for very high frequencies.

TDK Corporation presents a new series of very compact current-compensated EPCOS power line ring core double chokes for very high frequencies. The B82791H2*N010 series is available with current ratings from 1.5 A to 4 A at a nominal ambient temperature of +70 °C without derating, and for a nominal voltage of 250 V AC (50/60 Hz). Depending on the type, the inductance values are 14 µH to 100 µH. The utilized plastic material meets UL 94 V-0. To match significant requirements for specific applications such as drives, the plastic material fulfills the specifications for GWIT (+775 °C), GWFI (850 °C) and Ball Pressure (+125 °C). The design complies with EN 60938-2 (VDE 0565-2).

With dimensions of only 17.6 x 15.3 x 7.4 mm, these EMC components are extremely compact. Their very high resonance frequencies and increased saturation capability due to the special core material, and the complete omission of potting or any adhesives allow effective common-mode filtering at up to 300 MHz and beyond. Due to high stray inductance of up to 10 percent, these RoHS-compatible ring core chokes also effectively suppress the symmetrical interferences. The main application areas include compact switched power conversion applications, drives and post-design EMC tuning on semi-finished PCB.

Applications

  • Suppression of common-mode interferences at very high frequencies
  • LED driver circuits
  • Switch-mode power applications

Main features

  • Very compact design
  • Suitable for post-design EMC tuning on finished PCB
  • Very high resonance frequency and high saturation capability due to special core material and omission of potting
  • Effective common-mode filtering up to 300 MHz
  • Up to 10 percent stray inductance RoHS-compatible

TDK Power Capacitors, new DC Link capacitors nueva serie B2563xE para inverters y Fast Switch power modules

“TDK , marca de calidad de la que somos distribuidores en Dachs S.A, amplía el catálogo de DC Link Capacitors con nueva serie B2563xE para aplicaciones inverter, ferrocarril, fotovoltaico,etc.”

Power capacitors: TDK introduces new DC link capacitors with exceptionally low ESL.

TDK Corporation presents a new series of EPCOS power capacitors for DC link applications. The new capacitors are available for rated voltages of 700 V DC to 2000 V DC and cover a capacitance range of 20 µF to 270 µF. The current handling capacity can be up to 60 A at 65 °C with the ability to tolerate current peaks of up to 7.5 kA. The maximum permissible hot spot temperature is 85 °C.

The capacitors’ extremely low ESL values can be as low as 13 nH, depending on the type. Thanks to this and the low ESR values of min. 0.9 mΩ, the capacitors of the B2563xE* series are suitable for inverter solutions with fast-switching power modules. The low ESR value remains stable even at high switching frequencies of 100 kHz, while the low parasitic coefficients prevent significant voltage overshoots even when high currents are switched off.

The capacitors’ plastic cylindrical cases conform with UL 94 V0. Two connection types are available: M8 threaded bolts or M5 threaded holes. Typical applications include fast-switching converters and inverters for photovoltaic systems, traction in railway technology and inductive heating systems.

Main fields of application

Fast-switching converters and inverters for photovoltaic systems, traction and inductive heating systems.

Main features and benefits

Rated voltage of 700 V DC to 2000 V DC.

Capacitance range from 20 µF to 270 µF.

Extremely low ESL of max. 13 nH, ESR of min. 0.9 mΩ.
