Würth Develops Phototransistor-Type Coplanar Optocouplers
WALDENBURG, GERMANY — Würth Elektronik is now offering pho- totransistor-type optocouplers for the first time, the WL-OCPT series 816. These coplanar optocouplers consist of an infrared LED on the input side and
Single-Phase EMC Block Filter from SCHURTER
SANTA ROSA, CA — SCHURTER has completed its portfolio of single- phase EMC filters with its FMBB EP series, a new generation of ultra- compact filters with high-performing attenuation. The new double-stage filter family is more powerful than typical filters, meeting the space con- straints and performance require- ments of today’s state-of-the-art elec- tronic devices.
a phototransistor on the output side. They are characterized by a high
insulation voltage of 5 kV and a stable current transfer ratio (CTR) over their entire operating temperature range. The WL-OCPT series is available in five different THT and SMT contact- ing variants, each with five CTR bin- nings from 50 to 600 percent. The company went for a copper
lead frame, rather than iron, to make the components more durable. The WL-OCPT series is suitable for use in power supplies and chargers, com- puters and microprocessors, electric

meters, and many other applications that require signal transmission
together with safe galvanic isolation. The coplanar structure inside
the white housing keeps a fixed dis- tance gap to ensure overvoltage pro- tection. The operating temperature range of the WL-OCPT series is –67 to +230°F (–55 to +110°C). The max- imum collector-emitter voltage for
the series is 80V. Contact: Würth Elektronik eiSos GmbH & Co. KG, Max-Eyth-Strasse

FMBB EP series EMC filter. The FMBB series includes high-
quality components, such as correct- ly sized film capacitors and chokes with highly permeable cores and a steel housing. The housing is com- pletely closed and spot-welded at the bottom. These are critical design aspects of the FMBB EP series’ abili- ty to provide low frequency common- mode attenuation, high- to low-fre- quency differential attenuation and broadband attenuation. The filter family is particularly
suited for use in applications con- fronted with the most stubborn elec- tromagnetic interferences, such as any equipment with extremely fast semiconductor processing speeds at high switching frequencies, which are typically integrated into larger scale operations, where exposure to other noise generating devices exist. The FMBB EP filters are
designed for rated currents ranging from 1 to 36A at an ambient temper- ature of 104°F (40°C) up to 250V. Standard versions can be used over a temperature range from –40 to +212°F (–40 to +100°C), with manu- facturer recommended deratings at higher temperatures. Variations in leakage currents are available for different applications — the standard version with 0.9 to 3.8 mA, for med- ical technology less than or equal to 5 or 80 µA. The FMBB EP is easily installed to a chassis using the screw flange on both ends. The series is
ENEC and cURus approved. Contact: SCHURTER, Inc., 447
