Ohmite isn’t just celebrating its 100th anniversary at electronica this year, it is showing a host of new products designed for the 21st century. The company’s 100 years of resistor technology, design, and manufacturing experience has culminated in both new products and new services.

With their eyes fixed firmly on the future, Ohmite and Arcol have chosen to prioritise market sectors for this electronica and will subsequently be showing a host of new products designed for applications in the energy, medical and transport industries among other established markets where their products are already well known.

  Two years ago at electronica, Ohmite launched their first ceramic heatsink and a prototype resistor using the same material, this year they will have a complete range to talk to customers about following this week’s acquisition of the electronic components business of Kanthal, a part of Sandvik Group. 

  Having launched a new product almost every month since the last electronica, there will be plenty to see on the Ohmite/Arcol stand (Hall B6-101). Development by both companies has resulted in products designed for engineers by engineers. 

Based on its aluminum RA-T2X-38E heatsink, Ohmite has produced its first Ceramic heatsink. The WC-T2X-38E is the first of several models planned for 2017 and is made from high purity ceramic which is gaining popularity with engineers as the solution to many thermal management requirements.

  Offering resistance values up to 10TΩ, Ohmite’s Ultramox series supports their popular Slim Mox resistor family and allows for tighter tolerances than previously available, down to 0.25%, and TCR’s as low as 25ppm. Offered in four standard sizes, the series is rated from 10 to 30kV and from 1 to 3W.

Ohmite Manufacturing has achieved true global manufacturing status, following the acquisition of Arcol in the UK by parent company Heico. Arcol and Ohmite, on behalf of Heico, will manage Arcol's operations going forward.

As the company celebrates its 90th year, the Ohmite stand will feature a blend of the old and the very new. There will be innovative heatsink designs, high energy ceramic composition resistors and surface mount current sense resistors, alongside stamps, coins, porcelain, pottery, books, a clock and a Harrods silver plated coffee pot (all from 1925).

Expanding the company's popular FCSL range of SMD current sense resistors, Ohmite has announced a 10W version featuring very low and stable TCR of ±100ppm/°C. Operating over a temperature range from -55 to +155°C, the FCSL150 is supplied in a 7.5x15x1.1mm 5929 package designed for automatic insertion.

  Providing a 400J energy rating with average power of just 2.5W, the EY Series of high energy ceramic composition resistors has been announced by Ohmite. The company has claimed that no other resistor on the market handles energy spikes of this magnitude in such a small package.

Following the launch of their C40 heatsink designed to accommodate a 40mm fan, Ohmite have received numerous requests from designers to provide a larger option for mounting up to six TO-247 and/or TO-264 devices, plus larger components. The B60/C60 heatsink does this, but it also goes one step further.

Available in a 1206 package with a small footprint of just 3.2x1.6mm, the FC4L32 surface mount current sense resistor has been announced by Ohmite. The smallest device in the company's expanding FC4L family, the resistor features a 1W power rating and can handle currents of up to 45A.

Ohmite Manufacturing announces the new MC4 Series a multi-configuration single surface mount DIP package with four high voltage (2500 VDC) resistors.

Ohmite’s new MC4 Series offers four high voltage - 2500 VDC - resistors in a single surface mount 7575 DIP package as a standard part, but, if required, customers may select any combination of resistor values and tolerances using a new part numbering scheme. Once customers have defined their specific needs, Ohmite will assign a unique part number to their product for future use by customers or distributors alike.

Ohmite has today announced the release of a new series of epoxy coated high voltage axial leaded resistors. The new Maxi Mox Series resistors use an epoxy, rather than silicon coating in order to reduce the costs and decrease lead times of this popular component.

Ohmite have announced the introduction of a new Heatsink System. The C40 Heatsink System provides designers with a variety of cooling options for up to four TO-247 and/or TO-264 devices which now includes the addition of fans for forced air cooling. The 58mm long heatsinks can be used individually or in pairs.

Ohmite Manufacturing announces the new 5W and 7W surface mount wirewound resistors for high power density applications. The new RW5 and RW7 Series SMD wirewound resistors feature a ‘finned’ body style in order to maximize surface area, and therefore cooling capacity, without taking up excessive PCB space.

A new range of high energy resistors from Ohmite combine the benefits of non-inductive performance and high power density. Resistant to power surges such as lightning strikes, the first in the series, the TP810, would commonly be used to buffer the energy required to switch on and turn off components like large compressors and motors or spikes caused by faulty wiring or problems with the utility such as downed power lines.

By using very simple idea from their heatsink designs, Ohmite has developed an SMD wirewound resistor which meets a 5W plus power rating, providing a solution to a problem which has dogged resistor manufacturers for years.

Having achieved success in the medical equipment market with custom made parts which have applications in personal fibre optic theatre lighting used by surgeons, Ohmite have introduced two new miniature heatsink parts, the SV-LED-314E (14mm height) and the SV-LED-325E (25mm height) to address other opportunities where component size is a major consideration.
