Parasitic capacitance, inductance, and displacement current
When two electrical conductors are physically close, carry a charge, and there’s a voltage potential between them, they create a virtual capacitor between them, even if the conductors are insulated. The virtual capacitor between them is known as parasitic or stray capacitance. This can happen anywhere but is most troublesome between traces on printed circuit […]
High-reliability thick-film resistors come in 0603-sized packages
TT Electronics has announced the introduction of two additional resistor types that expand and enhance its high-reliability CR and HR series. The latest versions of these thick-film chip resistors are in the smaller 0603 size and hence offer greater opportunities for use in compact circuits where guaranteed performance and footprint size are critical. For use […]
Ultra-low-ohmic shunt resistors target automotive systems and industrial equipment
A more compact version of the PSR series of high power ultra-low-ohmic shunt resistors is now available for current detection in automotive and industrial applications. The PSR100 series adopts a high-performance metal alloy as the resistive element to provide superior temperature coefficient of resistance (TCR). In addition, leveraging original precision welding technology makes it possible […]
High pulse-withstanding resistors in a compact package
The HPWC (high pulse withstanding chip) range of high energy surge resistor products are designed to maximise the level of surge performance available in a single-sided flat chip design. The HPWC range targets protection and discharge applications in compact power supplies and power control circuits that need a resistance tolerance of five percent. Available in […]
Heatsinks boost thermal performance of power resistors
TT Electronics has announced the WMHP-HS heatsink specifically designed to optimise the thermal performance of its WMHP series power resistors.

Automotive-grade resistors deliver power dissipation to 0.4 W
Vishay Intertechnology, Inc. introduced a new series of Automotive Grade thin film chip resistors that features the industry’s highest rated power dissipation in the compact 0402, 0603, and 0805 case sizes. For electronics in automotive, industrial, and renewable energy applications, Vishay Beyschlag MC HP series devices combine high operating temperatures to +175 °C with low […]
High-rel chip varistors for automotive apps withstand 25 kV
In recent years, as cars have become equipped with many additional functions such as advanced driver assistance systems (ADAS) and in-vehicle infotainment (IVI) networks, the downsizing of the ECUs and increased reliability have become even more important. As a result, ESD and surge protection devices also need to be smaller and offer higher reliability. TDK […]
