High-impedance chip beads provide noise suppression in smartphone, tablet, mobile device power and signal circuits
TDK Corporation announced the development of the MMZ0402EUC series of chip beads, with the lowest DC resistance for a chip bead its size. The two new types with their respective impedance values of 150 Ω and 180 Ω at 100 MHz, feature DC resistance values of only 0.62 Ω and 0.69 Ω. This results in […]
Designing overvoltage protection for fire detection equipment
Author: Sonja Brown, EPCOS, a TDK Group Company The analyst firm Gartner predicts there will be nearly 25 billion IoT-enabled devices by 2020 – many of which will take the form of home automation, safety, security, appliance and entertainment equipment. A recent article on Smart Home technology cited a Coldwell Banker Real Estate survey that […]
Metal oxide disk varistors work up to 105 °C
TDK Corporation presents leaded EPCOS metal oxide disk varistors, which have now been approved for an increased operating temperature of 105 °C (previously 85 °C). The reason for this is the recertification of the B722* series of varistors in accordance with UL 1449, 4th Edition, and IEC 61051. Raising the permissible operating temperature to 105 […]
PTC-based inrush current limiters handle up to 560 Vac
TDK Corporation has extended its 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 […]
Power capacitors handle up to 60 A, 600 Vrms
TDK Corporation has significantly extended its range of EPCOS single-phase power capacitors for industrial electronics. The capacitors of series B32370 through B32374 are designed for rated AC voltages of between 250 VRMS and 600 VRMS, cover a capacitance range from 5 µF to 600 µF, and feature a maximum current capability of between 15 A and 60 […]
Low-profile SMD capacitors handle 900 V
TDK Corporation has extended the CeraLink™ series with two low-profile (LP) types designed for a rated voltage of 900 V DC. The SMT capacitors have a capacitance of 0.25 µF and feature different terminations: the B58031I9254M062 type with L-style termination has dimensions of 10.84 mm x 7.85 mm x 4 mm, while the B58031U9254M062 with J-style termination measures only 7.14 mm […]
