Frame core power line chokes with vertical design from EPCOS
TDK Corporation has extended its range of EPCOS frame core power line chokes with the B82733V* series in a vertical design. The new series complements the existing horizontally designed B82733F* series. The vertical design is particularly advantageous when there is limited space on the printed circuit board. With an insertion height of 27 mm, for example, the new chokes have a footprint of just 29 mm x 15.5 mm. This is more than 30 percent smaller than that of the horizontal version which, with a height of 14 mm, requires an area of 26.5 mm x 24.8 mm.
The current-compensated chokes are designed for a maximum voltage of 300 V AC and offer inductance values of between 10 mH and 100 mH. At an operating temperature of 40°C, the chokes can handle rated currents of between 0.7 A and 2.3 A. Both the plastic frame and the epoxy resin coating meet UL94 V-0 requirements.
In addition to their good common-mode suppression, the chokes feature good differential-mode suppression thanks to their relatively high stray inductance of about two percent. In many cases this means that no additional components for differential-mode suppression are required. The chokes are therefore particularly suitable for new designs of switch-mode power supplies with high switching frequencies.
The new components are approved according to ENEC (VDE) and UL and are RoHS-compatible.
Main applications
- Low to medium power switch-mode power supplies
Main features and benefits
- Footprint reduced by more than 30 percent
- Good suppression of both common-mode and differential-mode interference
- Approved according to ENEC (VDE) and UL
