Update Time: 2019-12-20 22:00:23

ProTek Devices has added to its family of overcurrent protection devices with new surface-mountable poly-switch temperature coefficient thermistor (PPTC) devices that include the company’s first resettable PPTC thermistors. The new components are suitable for circuit protection in many applications such as automotive, mobile device battery packs, computer motherboards, and more.

The new components include the PMPS150-1812; PMPS150E-1206; PMPS200-1812; PMPS200D-1210; PMPS260C-1812; and PMPS380E-1206. These surface mount device (SMD) PPTCs are designed for overcurrent protection. Two series are also being introduced: the PLRO1206 and the PLRO1210, which are resettable SMD PPTCs for overcurrent protection.

The PMPS150-1812 comes in an 1812 size with a weight of 0.0476 grams. It features 1.50 amps maximum holding current, 3.00 amps minimum trip current, 24 volts maximum interrupt voltage. Maximum fault current is 20 amps, maximum time to trip current is 8.00 amps at 1.50s and, minimum / maximum resistance is 0.040 / 0.110 ohms. The PMPS150E-1206, in a 1206 size, weighs 0.0058 grams. The PMPS150E-1206 has 1.50 amps maximum holding current, 3.00 amps minimum trip current and, 8 volts maximum interrupt voltage. It has a maximum fault current of 100 amps, maximum time to trip current of 8.00 amps at 0.30s and, minimum / maximum resistance of 0.030 / 0.120 ohms.

The PMPS200-1812, size 1812, has 2.00 amps maximum holding current, 3.50 amps minimum trip current and, 8 volts maximum interrupt voltage. The maximum fault current is 100 amps, maximum time to trip current is 8.00 amps at 2.00s and, minimum / maximum resistance is 0.020 / 0.070 ohms. The PMPS200D-1210, size 1210, weighs 0.0164 grams. It has 2.00 amps maximum holding current, 4.00 amps minimum trip current and, 6 volts maximum interrupt voltage. Maximum fault current is 50 amps, maximum time to trip current is 8.00 amps at 5.00s and, minimum / maximum resistance is 0.004 / 0.028 ohms.

The PMPS260C-1812, size 1812, features 2.60 amps maximum holding current, 5.00 amps minimum trip current and, 8 volts max interrupt voltage. Maximum fault current is 100 amps, maximum time to trip current is 8.00 amps at 4.00s and, minimum / maximum resistance is 0.010 / 0.040 ohms. The PMPS380E-1206, size 1206, features 3.80 amps maximum holding current, 7.60 amps minimum trip current and, 6 volts maximum interrupt voltage. Maximum fault current is 50 amps, maximum time to trip current is 16.00 amps at 5.00s and, minimum / maximum resistance is 0.001 / 0.015 ohms.

The PLRO1206 and PLRO1210 provide very low resistance, high current ratings and fast times to trip. The PLRO1206 and the PLRO1210 are in a small footprint lead-free 1206 package which weighs 0.0164 grams. The PLRO1206 series consists of the PLRO1206-300 and PLRO1206-380. The PLRO1206-300 features 3.0 amps holding current and 6.0 amps trip current. The PLRO1206-380 features 3.0 amps holding current and 8.0 amps trip current.

The PLRO1210 series consists of the PLRO1210-190, PLR1210-300 and PLRO1210-380. The PLRO1210-190 features 1.9 amps current holding and 4.9 amps trip current. The PLR1210-300 features 3.0 amps holding current and 8.0 amps trip current. The PLRO1210-380 features 3.8 amps holding current and 9.0 amps trip current.
