 | What's the difference between rubber, acrylic, and silicone PSA tapes for assembly?
While there are a broad range of PSA tapes that provide different levels of quick stick, adhesive strength, adhesion to difficult substrates, environmental resistance, and more, the three most common categories that cover the widest variety of use cases are rubber, silicone, acrylic. What are the differences between these tapes? Which applications are best suited for each? Engineered Materials runs through the strengths and weaknesses of each type, providing general guidelines of when you'd want to use acrylic, rubber, or silicone PSA tapes.

 | Feel the difference: 2-shot injection molded knobs sample pack
In 1979, Rogan was the first knob company to mold a knob utilizing the 2-shot injection molding process, which uses a single plastic molding machine specially made to inject two materials sequentially or one on top of the other. If you've ever used a plastic toothbrush with a colorful rubber grip, it was likely 2-shot injection molded. Create a competitive advantage for your products. You can add markings, custom colors or graphics, and even glow-in-the-dark materials. Request a sample of control knobs or clamping knobs -- or both.

 | What motor torque constant to use for drive type: Theory and application
Calculating motor torque from available drive current can be confusing due to many different drive types and the multiple ways current is specified. This informative online paper from Celera Motion provides the key formulas for torque constant and motor current from the fundamental principles of three-phase motor theory. It also walks through the many ways torque can be calculated. This information applies to a brushless motor (BLAC or permanent magnet synchronous machines) configuration.

 | High-current chokes for automotive and industrial
TDK Corporation presents the B82559A*A033 series of new shielded EPCOS ERU33 high-current chokes for through-hole mounting. Designed for very high saturation currents from 32 to 83 A at 100 C, the six new types cover a range of inductance values from 3.2 to 10 microhenry. Typical automotive applications are buck-boost chokes for DC-DC converters (e.g., for 48-V on-board power supplies or differential mode chokes in the input filter of onboard chargers) or as storage and output chokes in high-current supplies and PoL supplies for industrial electronics.
