The QAS Series' wide range of specifications (up to 1.0uF capacitance, 680 ohms resistance and 1600 Vdc/660 Vac voltage rating) provides versatility across various applications. This innovation could potentially extend product lifecycles and reduce maintenance costs in industries relying heavily on electromechanical systems, such as industrial automation, automotive and consumer electronics.
Knowles' introduction of the QAS Series positions the company to capitalize on the growing demand for reliable and long-lasting electronic components. This product line aligns with industry trends towards:
- Miniaturization of electronic devices
- Increased focus on product longevity and sustainability
- Reduction of electromagnetic interference in sensitive applications
The QAS Series could potentially strengthen Knowles' market position in the capacitor and RF products segment. By addressing critical issues like arcing and EMI/RFI interference, Knowles is likely to attract customers from high-value sectors such as aerospace, medical devices and telecommunications. This product launch may positively impact Knowles' revenue streams and reinforce its reputation as an innovator in micro-acoustic and electronic solutions.
The QAS Series reduces early failures in relays, switch contacts, and solid-state components
Knowles' Cornell Dubilier brand QAS Series devices provide single-device RC networks in two-lead radial packages. QAS networks extend the operating life of electronic and electro-mechanical devices by reducing and/or eliminating electrical arcing at the point of electrical contact. Without a snubber circuit, arcing often leads to early failures in relays, switch contacts, and solid-state components such as SCRs and TRIACs.
When the contacts in an arc suppression circuit open, a voltage is applied across the capacitor instead of the relay contacts. This prevents arcing because the capacitor charges faster than the contacts open. When the contacts close, the inrush current from the charged capacitor and source can exceed the safe conductance of the contacts. The resistor in the network limits the inrush current significantly, reducing the arc produced at contact closure, and extends the service life of the contacts. In practical applications, for DC voltage, the RC network is typically connected across the relay contacts, and for AC voltage, it is connected across the load.
The QAS is also effective at reducing spark-generated EMI/RFI that can cause interference with the operation of a circuit.
Each device consists of metallized polyester capacitor RC network, coated with a flame-retardant epoxy. Having a single device containing an RC network has advantages for circuit designers rather than building discrete networks. The single device is more compact, pretested, and environmentally more robust. The QAS product line includes 24 devices with:
- Capacitance values of up to 1.0uF
- Resistor values up to 680 ohms,
- Rated voltage options up to 1600 Vdc/660 Vac, 60 Hz
- Operating temperature range –55 °C to +85 °C at full rated voltage.
QAS Series devices are available now from Knowles' authorized distributors. To learn more about Knowles' Cornell Dubilier brand QAS devices, visit https://www.cde.com/new-product/QAS/.
