B40900 series hybrid polymer aluminum electrolytic capacitors
TDK has introduced B40900 series hybrid polymer aluminum electrolytic capacitors
The range of hybrid polymer aluminum electrolytic capacitors has been extended with a new SMD series. The components are now available in 25 V DC / 330 μF and 35 V DC / 270 μF versions, each with dimensions of 10 x 10.2 mm (d x l). The capacitors, which are RoHS-compatible and qualified to AEC-Q200, are designed for a maximum operating temperature of 125 °C and offer a long service life of at least 4000 hours.
Two electrical parameters in particular characterize the compact capacitors: their extremely low ESR value of ≤20 mΩ and the high ripple current capability of 2.8 A at 125 °C and 100 kHz. These excellent values are made possible by the hybrid polymer technology.
In addition to automotive electronic control units, the capacitors with the ordering codes B40900B5337M000 (330 μF) and B40900B7277M000 (270 μF) can also be used in industrial applications.
The new SMD series supplements the world's first axial hybrid polymer aluminum electrolytic capacitors. These capacitors with dimensions of between 14 x 25 mm and 16 x 30 mm (d x l) are designed for rated voltages of 25 V, 35 V or 63 V and offer capacitance values from 390 to 2100 μF. Despite their low weight and volume, they offer a very high current capability for automotive power modules.
