Murata tightens PTC thermistor tolerance for overheat detection applications
Murata has announced 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.
