Bourns has created an AEC-Q200 compliant 1:1 signal isolation transformer for automotive battery management systems. SM91872AL is surface-mount and will fit into a 17.4 x 10.6 x 8.1 envelope – including its visible legs. Inductance is 150 to 450µH (100kHz 100mV) across its -40 to +125°C operation range, and leakage inductance is 1µH max. Both sides have a maximum resistance ...
BEC Distribution is stocking LinkCom Transformer products. This range includes balun transformers for impedance matching, which are also suitable for DOCSIS3.0 and DOCSIS3.1 for data-over-TV-cable, and transformers for Qualcomm’ HomePlug. “LinkCom [also] works with chip vendors for HomePlug, G.hn, G3-PLC4 and has IC approval from several chip companies,” said BEC. Then there are gate drive transformers for power semiconductors, wireless charging ...
Premo has releases an integrated wound component package for automotive on-board LLC chargers rated up to 11kW. BCBM-11KW-004 combines 14:15 transformers and resonance inductors for three 3.6kW phases, taking in 400V and delivering 240-460V (<14.7Arms) when switched between 98 and 150kHz. The enclosure is 87(+lugs) x 38(+pins) x 158mm, and the parts inside are encapsulated. “The usage of specific thermal conductive ...
Bourns is aiming at high power density forward converters with a series of planar construction transformers. Called the PLN0xx-ED21 series, of them the company said: “Planar-style transformer components offer efficiency and power density advantages over conventional wire-wound transformer designs due to significantly reduced ac resistance losses.” Ratings vary across 48 to 70W with inputs from 33 to 57Vdc when switching ...
Yokogowa has revealed a power transformer variant of its WT5000 precision power analyser. WT5000TR is aimed at transformer manufacturers and offers 0.008% accuracy (power factor =1, 12months after calibration), making it “the world’s most accurate power analyser”, claimed the company. The analyser is delivered with calibration certificates from Yokogawa’s ISO17025 calibration laboratory, for low power factor measurements aimed at IEC60076-8 product compliance ...
Würth has added PoE++ transformers to its Mid-PoE power-over-Ethernet transformer series. These surface-mount devices are suitable for fly-back or active clamp forward converters that comply with the IEEE 802.3bt: the four-pair power-over-Ethernet known as 4PPoE or PoE++. “Demand for more power in PoE devices has risen due to advancements in smart and IoT applications,” according to the company. “In response, ...
Murata has announced an HPHF (high power, high frequency) transformer technology that uses a proprietary winding technique, allowing designers to “efficiently reach power and frequency levels that were never possible with conventional winding methods”, the firm says. Murata’s patented pdqb winding technology makes it possible to construct high frequency transformers of up to and over 400kW that can operate at ...
Würth is offering a surface-mount single port for 1000Base-T Ethernet industrial LAN connections. Each device contains four sets of inductive components, one for each twisted pair within the Ethernet cable. “WE-LAN AQ transformer convinces in an exemplary fashion in terms of crosstalk, insertion loss, return loss, differential and common-mode rejection,” claimed the firm. This data sheet gives the numbers as: crosstalk ...
RS Components has introduced a range of own-brand (RS Pro) current transformers which includes more than 100 devices. “These RS Pro components target applications including process control, motor control, utility power monitoring, control panels, and in switch-gear used in generators and electrical power distribution systems as well as in energy and building-management systems,” said the firm. Current transformers are used ...
GaN power transistors are giving new life to old ferrites as PSU designers seek magnetic components that can keep up with multi-MHz switching, according to Ferroxcube. “We are providing a lot of samples of 3F46 and 3F36 around the world,” the company’s product manager Artur Pawlak told Electronics Weekly at PCIM in Nuremberg. A decade ago the firm created a ...
