BI Technologies Develops Planar Heaters with Ratings up to 50W
Resistive heaters incorporate measurement circuitry for precise temperature control...
GLENROTHES, SCOTLAND (November 4, 2005) - Providing power electronics design engineers with the ability to deliver cost-effective, precise temperature profiling to electronics systems, TT electronics BI Technologies SMT Division has released a series of planar heater products with ratings up to 50W for military, computing, telecommunications, medical and commercial applications.
According to Jim Rieley, Sales Director for the TT electronics BI Technologies SMT Division, the company has developed surface mount, through-hole and custom-profiled planar resistive heaters. "Because they are available in a power rating range of 2W to 50W, they can be used for a wide variety of applications," Rieley explained. "For example, by spreading our 2W surface mount heaters over PC boards, heat is targeted to where it's needed to maintain optimum operating temperature in severe cold weather conditions. Engineers can also position our through-hole planar heaters (3W to 50W) adjacent to individual modules. This targets the heat, rather than heating the complete inside of enclosures, making this method of heating much more energy efficient."
The company also provides profiled heaters for outdoor computer accessories such as keypads, LCD displays, disk drives, card readers and various drive mechanisms, Rieley continued. "Our planar screened cermet heaters have extremely fast heat-up and recovery response characteristics, ensuring temperature stability at the point of use. These significantly outperform PTC heaters, whose relatively slow time to temperature and recovery time could, in certain circumstances, result in thermal cycling of the electronics, thereby shortening operational life. "
Thermal measurement components may be placed directly onto the substrate-heating element to provide an accurate interface to the control electronics, thus delivering precise temperature profiling. Additional applications include, for example, military systems, parking meters, medical equipment, telecom repeaters, external cameras, drive mechanisms and printers, as well as baby bottle warmers, domestic irons, hair straighteners, fish tank heaters, hair dryers, air fresheners and bug-free vapor atomizers etc.
Printed on ceramic substrates, the heaters are less expensive than most available products. Resistance ranges from 0.1 ohm to 100 Kohm, with tolerances to ±1%, TCRs to ±100ppm/°C, and operating temperature range is -55°C to +155°C. Maximum operating voltage for the heaters is 250V.
Because the heater products are semi-custom devices, pricing and lead times vary depending on customer specifications. Samples are available immediately for engineering evaluation and customer prototypes.
