Toshiba is aiming at air conditioners, air purifiers and pumps with an IGBT-based brush-less dc motor driver, suitable for sine-wave generation, in a ~13 x 33mm through-hole HDIP30 package. TPD4165K, as it will be know, can handle a maximum output of 3A, compared with 2A for the company’s earlier TPD4163K or TPD4164K. Absolute maximum input voltage has been raised to ...

Bourns is offering IEC-grade surge protection for ac or dc power rails with four DIN rail mount device series. 1270 series AC surge protection to IEC/EN 61643-11 Class I + Class II / T1+T2 1280 series the same, plus a thermal disconnector “that eliminates the need for up-stream over-current protection”, said Bourns. 1430 series DC surge protection to IEC/EN 61643-31 ...

Rohm has added a lineup of 600V super-junction mosfets in 6.5 x 7 x 1.66mm SOT-223-3 packaging. “In recent years, power supplies for lighting and motors for pumps are required to be smaller as devices become more sophisticated – spurring the demand for compact mosfets that are essential for switching operation,” said the company. “Generally, however, it has been difficult ...

CUI has introduced a range of ac fans with air flows 45 and 165CFM Across the 26 member CAF family there are three frame sizes – 120 x 120mm square either 26 or 38mm thick, and or 172mm circular (truncated to 150mm in one dimension) which is 51mm thick. Frames are aluminium, impeller is polymer (PBT, UL94V-0), and there is ...

Vox Power has introduced a compact 600W modular ac-dc power supply with four output slots, and a choice of eight output modules that can be mixed and matched among them. NEVO+600S is the name, and it measures ~41 x 78 x 134mm (plus blade terminals), giving it a 5 x 3inch footprint. “Tailored for demanding industrial applications where size, power ...

Cosel has used GaN transistors, planar magnetics and a modified fly-back topology to shrink a family of dc-dc power supplies. Called the TE series, the new supplies come in 45W (TECS45F and TEPS45F) and a 65W (TECS65F or TEPS65F) forms. TEPS versions have connections brought out to PCB pins and have a 1 x 2.3inch footprint, while TECS parts (right) ...

Power Integrations has introduced a 1,250V GaN version of its Innoswitch family of off-line constant-voltage constant-current quasi-resonant fly-back switcher ICs, making the options: 725V silicon, 750, 900 or 1.25kV GaN or 1.7kV silicon carbide. These are multi-die devices in a single package, with synchronous output and a proprietary inductive isolated feedback technique using bond-wires. The new devices have been dubbed ...

Powerbox has announced a ruggedised 1,200W ac-dc power supply for ground-based defense applications and harsh industrial environments. Called OFD1200A and suitable for use inside sealed enclosures, it has a metal chassis and requires cooling by conduction though its baseplate – which needs to be maintained between -40 and +95°C (derating applies sometimes – see the product manual). Shock and vibration ...

Cornell Dubilier Electronics is aiming at harsh environments with a series of X2, EMI-RFI suppression capacitors. “The MXH series is AEC-Q200 qualified and has been temperature, humidity and bias (THB) life tested. “The 2,000-hour test conducted at 85°C, 85% relative humidity at rated voltage subjected these components to twice the standard test hours required to meet IEC 60834, Class III-B ...

Schaffner is aiming at robots and other industrial applications with a range of three-phase mains interference filters. “FN3040, FN3041, FN3042 and FN3043 EMC filters are rated for currents of 10 to 30A at 50°C,” according to the company. “The tight-packaged filters are smaller than their predecessors yet offer superior performance.” Size is 128 x 63 x 50mm tall for the ...
