Small nichrome chip resistors handle 0.05 W
As design engineers continue to push the miniaturization of electronic devices while maintaining or increasing functionality, there is a corresponding need for smaller and more precise electronic components, such as chip resistors. If a precision application requires both small size and high-power handling, finding suitable precision resistors may be challenging. Stackpole recently increased the power […]
SMD Piezo sounder boasts louder output in a small footprint
Murata Electronics has newly developed the PKMCS0909E48H0-R1 SMD Piezo Sounder at 4.8 KHz which is a new and improved model from the current SMD sounder (PKMCS0909E4000-R1). The new sounder uses the same 9mm x 9mm footprint, is 1mm taller, uses new materials, operates at 800 Hz higher in frequency, and boosts the sound pressure level […]
