ISELIN, NJ--(Marketwired - Jul 18, 2017) - TDK Corporation today announced that it has extended the range of EPCOS PTC-based inrush current limiters. The four new versions of the B5921*J0130A020 series with plastic housing are designed for voltages from 280 V AC to 560 V AC, offer rated resistances from 22 Ω to 100 Ω at 25 °C and have a heat capacity of up to 2.3 J/K. They are UL approved and are qualified to AEC-Q200. The current protection devices are ideally suited for industrial and household electronics and automotive electronics.
The B594* and B597* series of leaded disk components offer rated voltages of between 260 V AC and 560 V AC. Depending on the type, their rated resistances are between 25 Ω and 1100 Ω. Also type-dependent, these protection devices have been approved in accordance with UL, IECQ and VDE. All types of both series are RoHS-compatible.
One great advantage of PTC inrush current limiters is their intrinsic safety. For example, if a short circuit should occur within a device when it is switched on, the component very quickly limits the current to non-critical values.
Typical applications for PTC inrush current limiters include converters and power supplies for industrial and household electronics as well as in e-mobility applications. These include onboard charging circuits and the charging and discharging of DC link capacitors in the drives of hybrid and electric vehicles.
Main applications
- Converters and power supply units for industrial and household electronics
- Onboard charging circuits and the charging and discharging of DC link capacitors in the drives of hybrid and electric vehicles.
Main features and benefits
- Wide range of rated voltages and resistances
- Approvals compliant with UL, IECQ and VDE
- Intrinsic safety
