Farnell stocks high-quality passive components from KOA

Published: 19 February 2021 - Rachael Morling

Farnell, an Avnet Company and global distributor of electronic components, products and solutions, has strengthened the depth and breadth of its market-leading passive component portfolio with KOA Europe GmbH’s (KOA) full range of around 2400 lines, all in-stock for delivery in Europe.

KOA is a leading global manufacturer of passive component solutions, specialising in thick film and thin film resistors for high reliability applications such as industrial, automotive, aerospace, telecommunications and medical, as well as more commercial markets.  Its broad portfolio includes high reliability thin-film, pulse tolerant/anti-surge thick film, shunts/current sense, high voltage and wide terminal resistors.
KOA’s full range of passive component solutions now available from Farnell include:
High reliability thin film resistors – With a T.C.R down to ±5 ppm and a tolerance as low as ±0.05 %, KOA’s thin film resistors are ideal for high precision circuits such as control and monitoring in industrial, medical and automotive applications. The RN73R series provides improved resistance to electrolytic corrosion, a wide operating temperature range from -55°C to +155°C and high stability compared to previous versions. The second product line in the series, RN73H, additionally offers enhanced moisture resistance and long-term stability performance.
Pulse tolerant and anti-surge resistors – The SG73 series is an ideal solution for protecting electronic circuits against extreme pulses and surges, especially in I/O protection, snubber and gate drive circuits. It has a pulse handling capability up to 10 times higher than standard flat chip resistors, making it suitable for use in automotive electronics, power supplies, motor control and more. The use of these parts means that fewer parts can be used leading to substantial space savings.
• Wide terminal resistors for high power density – The WK73R series features wide terminals on the long side of the resistor allowing for up to three times the power rating of a similar sized part with conventional terminations. The closeness of the terminals significantly reduces thermal stress between the resistor and the PCB. These parts are perfect for high power density circuits and gate drives used in environmental and industrial applications.
Current sensing resistors – KOA’s TLR series of current sensing resistors offer the high reliability and performance required for power control circuits such as motor control units, DC-DC converters, CPU current sensing and pulse applications. The special trimming eliminates hotspots giving a more reliable device with low parasitic inductance. The TLR series provides up to 5 W (100 A) rating and features superior corrosion and heat resistance.
Simon Meadmore, Global Head of IP&E at Farnell, says: “KOA continues to innovate and optimise its passive component solutions, ensuring engineers can easily overcome design and performance challenges. Our customers now have access to the highest quality passive components for automotive, environmental, industrial, medical and telecommunication applications as well as energy saving devices, home appliances, power supply units and more. The depth and breadth of KOA’s market leading range of chip resistors greatly enhances Farnell’s world-class portfolio of more than 360,000 passive components.”  
The complete KOA product range is now available from Farnell in EMEA and element14 in APAC.
