Current sensing for motor control applications often requires robust current handling and the lowest possible PCB temperatures. Unfortunately, high current or overload current handling typically means higher PCB temperatures. One cost-effective and popular solution to these requirements is a raised bare element sense resistor. The elevated bare element yields PCB temperatures of 30% to 40% […]
Applications
Clock oscillator achieves 0.2 ppm frequency tolerance
Depending on temperature range, the SiT7910 Super TCXO from SiTime can attain frequency stability of less than 0.1 ppm. Clock oscillator circuits serve two functions. They provide a clock timing signal for digital circuits such as microprocessors and they keep track of time, often for time-stamping of events. While oscillators for digital circuits typically produce […]
Common mode filter for automotive Ethernet reduces line-to-line capacitance
TDK Corporation has announced the introduction of its new ACT1210E Series (3.2 x 2.5 x 2.5 mm (L x W x H)) of common mode filter for automotive Ethernet 10BASE-T1S. Mass production of this new common-mode filter began in February 2023. This product is the industry’s first common mode filter for automotive Ethernet 10BASE-T1S. Adopting […]
Copolymer resin meets stricter regulatory requirements for 1.5Kv solar systems
SABIC launched a breakthrough polycarbonate (PC)-based copolymer resin, well-suited for photovoltaic (PV) connector bodies, that meets stricter performance and regulatory requirements for emerging 1.5Kv solar systems. The new LNP EXL9334P copolymer resin achieves the highest comparative tracking index (CTI) level (UL PLC0) and IEC as Material Group 1 (IEC MG 1). It also delivers low-temperature […]

Each of the […]
Precision thin-film resistors offer ±0.01% tolerances, ±2ppm TCRs
With the proliferation of electronics in nearly every market sector, there is an increasing need for precision resistors. For markets such as medical instrumentation and control, industrial and automotive controls, communications, and test & measurement, these precision resistors must maintain electrical and environmental stability long term. Stackpole’s RNCF series of precision thin film resistors meet these […]
What causes signal attenuation in a PCB and how can it be controlled?
Except for the most basic designs, system clock rates are inexorably creeping upward across a wide range of applications, from 5G telephony to automotive advanced driver assistance systems (ADAS), medical, industrial, and mil/aero systems. As frequencies rise into the GHz range, the need for impedance control to minimize signal attenuation and protect signal integrity gets […]
Automotive-grade chip resistors excel at handling pulses
High-reliability chip resistors can be more difficult to find and even more so when there are pulse handling requirements. Typically, the manufacturing process for thick film chip resistors allows for variation in the calibration trim, leading to variation in pulse handling performance. Stackpole’s recently released RPCA series addresses all these needs. The RPCA has limited to […]
