KOA flat chip resistors

KOA Corporation has released a range of flat chip resistor solutions, suitable for design engineers working in automotive, industrial, aerospace, medical, instrumentation and power conversion sectors.

The RN73R is a high-precision thin film resistor that replaces the RN73 series with improved electrolytic corrosion resistance and higher stability. The series’ RN73H resistor is designed for tough environments and is useful for high-precision circuits for automotive, aerospace and other challenging applications. Despite their ultrathin film, these resistors have good moisture resistance due to an additional inner protective layer.

The RS73 is a high-precision resistor that uses thick film technology, which makes it suitable for long-term stability when designing high-accuracy sensing or voltage detection circuits in automotive, industrial and measuring applications where ESD sensitivity is an issue.

The SG73P is an endured pulse power thick film resistor that has approximately seven times the pulse handling capability of standard flat chip resistors, the company says. Its special trimming gives it a high power rating, which means the device can be dropped onto the pads of a similar-sized conventional part, thus increasing the power capability without changing the PCB layout.

For designers who need to conserve board space, the WK73R wide termination thick film resistor offers several advantages. For example, the 0612 chip size allows a 6x power rating compared to standard 1206 parts, which saves board space by improving heat dissipation. The larger terminals also enhance terminal strength and the smaller distance between the terminals reduces expansion stress.
