AVX Develops 0402 Thermistor with Enhanced Response Time
MYRTLE BEACH, S.C. (December 7, 2004) - AVX Corporation recently developed an 0402 surface mount thermistor for applications such as mobile phones, hard disk drives, laptop computers and compact disc players. Designated the NB23 Series, the NTC (negative temperature coefficient) thermistors are specifically designed for temperature compensation and control applications in handheld and portable electronics equipment.
"With the growing concerns about mobile phone safety, AVX's 0402 thermistor is an ideal design solution for handset manufacturers, as well as other electronics OEMs," said Ron Demcko, AVX Applications Engineering Manager. "Its small size allows for greater design flexibility, such as placement in a battery pack as a temperature sensor, while providing the same high-level of accuracy and a better response time than in larger NTC thermistor devices."
According to Demcko, the NB23 Series can be used as a temperature sensor for the battery pack's charge control circuitry, and the thermistors are also ideal for temperature measurement on LCD displays, especially those used on high resolution color displays.
The NB23 Series thermistors feature resistance values from 10Kohm to 100Kohm, with standard tolerances of 5%, 10%, and 20%. Maximum dissipation is 150mW, with a thermal dissipation factor of 0.8mW/°C and a thermal time constant of 3 s. Operating temperature range is from -55°C to +150°C.
The NB23 Series thermistors also feature a nickel barrier termination that provides excellent solderability characteristics for lead free (high temperature) soldering processes.
In addition, AVX offers NTC thermistors in 0603, 0805 and 1206 case sizes, as well as a comprehensive range of leaded thermistor devices.
Typical pricing starts at $0.11 in quantities of 10,000. Lead times are from stock to eight weeks.
