We respond to the needs of 'unable to eliminate localized heat buildup (hotspots) in high-density implementation of power electronics and high-frequency circuits' and 'wanting to create a heat dissipation path while maintaining electrical insulation for circuits that cannot be grounded.' With the recent miniaturization and high power output of devices, the difficulty of thermal design has risen sharply. Our product is currently attracting significant attention from many developers working on such 'next-generation designs,' leading to a rapid increase in inquiries. 【This product features】 • Complete electrical insulation with powerful thermal bypass: It uses aluminum nitride (AlN) substrate, boasting a high thermal conductivity of 170 W/m·K. As an electrically insulated thermal conductor, it exhibits excellent thermal conductance of up to 250 mW/°C. • Low capacitance for high-frequency reliability: The capacitance is extremely low, ranging from just 0.07 pF to 0.26 pF, ensuring that it does not compromise the characteristics of RF amplifiers and communication devices. It eliminates the need for large heat sinks or expensive multilayer heat dissipation substrates, strongly supporting the standardization of designs with a single solution through SMD (surface mount technology).

Resistors have a "rated voltage" determined by their rated power and resistance value. Basically, voltages exceeding this rated voltage cannot be applied, but for pulses and surges, manufacturers may specify allowable ranges. Our company has established regulations such as "maximum overload voltage → short-term overload specification of 2.5 seconds" and "one pulse → specification for one pulse of less than 1 second," allowing usage that exceeds the rated voltage if conditions are met. This document explains the pulse usage judgment flowchart for "one pulse" and "repetitive pulses," as well as the underlying concepts and specific examples. Please take a moment to read it.

The difference between current detection and shunt... Originally, each has a different meaning and usage, but in reality, they are now used interchangeably to refer to the same functions or products, and there are no clear definitions or classifications in terms of product specifications or structure. "Current detection/shunt resistors" are used for purposes such as voltage control, overcurrent limitation, and battery level detection. We provide a clear introduction to the operating principles and characteristics of resistors by using diagrams and tables.
