Recently, Vishay Intertechnology, Inc. (NYSE: VSH) announced that it has increased the operating temperature range of its HOTcap ® K...H series automotive grade radial lead multilayer ceramic chip capacitors (MLCC) to +200 °C. The industry's highest temperature for Class II ceramic through-hole devices.

The Vishay BCcomponents lead MLCC is believed to operate for 500 hours at temperatures ranging from -55 ° C to +200 ° C. There is no time limit at +175 ° C. The device has good high temperature performance from 100pF to 1μF and the capacitance tolerance is strictly ±5%.
Class I and Class II ceramic MLCCs use a very stable C0G dielectric with a capacitance variation of ±30 ppm/K and a X0U ​​dielectric with a temperature range of -55 ° C to +175 ° C and a TCC of +22% / -56%. The X0U dielectric also meets the X7R specification. The capacitance change from -55°C to +125°C is ±15%, which is up to the X9V specification. The capacitance change from -55°C to +200°C is +22%/-82%. . For direct soldering to the lead frame, or plastic injection molding, the capacitor uses straight leg leads or bent leads with a pitch of 2.5 mm and 5.0 mm. The lead diameter is 0.5 mm or 0.6 mm and is made of 100% tin-plated copper-clad steel.
Capacitors are lead-free, RoHS compliant, halogen-free, and coatings made of refractory epoxy meet UL 94 V-0.
A new rule from the Drug Enforcement Administration (DEA) threatens to upend the American hemp industry, and could even result in criminal prosecutions for manufacturers of CBD and delta-8 THC products.
The DEA says the [interim final rule," issued Aug. 20, is simply a matter of adjusting its own regulations to account for changes to the Controlled Substances Act that were mandated by the 2018 Farm Bill (or Agricultural Improvement Act) that legalized hemp and CBD production. The new rule [merely conforms DEA`s regulations to the statutory amendments to the CSA that have already taken effect," says the agency. The new rule doesn`t break any ground, according to the DEA.
But many experts on cannabis and hemp law say the DEA rule creates a potential pathway the law enforcement agency could use to prosecute hemp processors and producers of CBD (cannabidiol) and delta-8 THC (or Δ8THC) products. There are two issues: partially processed CBD, and [synthetically derived" delta-8 THC.
