Chemical-Resistant Canopy Hoods from HEMCO
Independence, MO — Canopy Hoods are designed to collect and exhaust corrosive vapors, heat, steam, and odors. HEMCO offers them in 36, 48, 72, and 96 in. (0.9, 1.2, 1.8, 2.4m) widths, in wall or island models. Canopy hoods are available in
either molded, chemical-resistant, flame-retardant, one-piece composite resin or fabricated of welded, Type 304 stainless steel. Wall canopy hoods include a wall mounting kit. Island canopy hoods have an option- al suspended mounting kit available. In addition, custom-size canopy hoods can be manufactured to exact size and design requirements. Corner canopy hoods are the solu-
tion to maximizing wasted space in corner areas, and can either be wall- mounted or suspended from the ceil- ing. Optional corner composite work surface and corner tables are available. With any of the canopy hoods, vapor- proof lights, switches and side and rear enclosure panels are offered to prevent
RoHS cross drafts and further improve air-

TDK Intros Ultra-Thin Piezo Speaker
Irving, TX — TDK Corporation has developed an ultra-thin piezoelectric speaker — PiezoListen™ — that pro- duces sound over a broader frequen- cy range and with a greater output in the low range than any existing piezoelectric speakers. It offers an operating frequency range of 400 to 20,000 Hz and achieves a high sound pressure of 80 dB, even at low volt- ages of 24 VP-P or below. Due to its
low profile,
PiezoListen enables designers to overcome installation space con- straints. The new speaker element has a very flexible form and is able to produce sound from many different kinds of objects and materials. With the new PiezoListen piezo speakers, TDK is helping customers to design innovative audio applications. Not only is the standard format for video content rapidly moving to 4K and 8K

RFMW Offers Timing Technology to Solve 5G Challenges
San Jose, CA — RFMW, Ltd., announces design and sales support for a MEMS-based oven controlled oscillator (OCXO) platform. SiTime’s SiT5711 OCXO combines MEMS res- onators with programmable analog, innovative packaging and high-per- formance algorithms for a vibration resistant solution that can be up to 20 times better than what is current- ly available. The SiT5711 offers ±5 ppb frequency stability and 50 ppt/°C frequency slope (DF/DT). Factory-programmed to any fre-
quency between 1 and 60 MHz, this OCXO is available in a 0.4 x 0.3 in. (9 x 7 mm) package. It is also available in common OCXO footprints such as 1 x 0.9, 0.8 x 0.5, and 0.6 x 0.4 in. (25 x 22, 20 x 13, and 14 x 9 mm) to enable drop-in replacement of legacy quartz OCXOs. There are no restric- tions on PCB placement and no mechanical shielding is needed for
thermal isolation. Applications
include 4G/5G remote radio heads (RRH) and pole top mounted radios, base stations, SONET/SDH Stratum
resolutions, but more and more video content is offering multichannel audio as well.
