Murata Tightens PTC Thermistor Tolerance for Overheat Detection Applications
Hoofddorp, Netherlands: Murata announced today the availability of the PRF15 series of miniature positive temperature coefficient (PTC) thermistor designed specifically for overheating detection applications in a broad range of consumer electronics devices. Believed to have the industry's tightest temperature tolerance of +/- 3 degrees C, the series lineup comprises devices with detection temperatures in the range of +80 degrees C to +150 degrees C in 10 degree C steps. Across the series the thermistor resistance at +25 degrees C is 1 k ohm, with preferred detection points occurring at 10 k ohm and 100 k ohm values. For example, the PRF15AR102RB6RC part detects +135 degrees C at 10 k ohm and +150 degrees C at 100 k ohm. Maximum voltage is 32 VDC.
Available in a compact 0402 package measuring only 1.0 x 0.5 mm, this surface mount device meets the increasing need for consumer end-products to incorporate a means of detecting overheating within space constrained applications. These can include notebook and tablet computers, cellular phones and LED lighting modules. Protection circuits within lithium-ion battery packs and motor coils are other possible applications.
