Radial Leaded > 30R Series
The 30R Series radial leaded device is designed to
provide overcurrent protection for low voltage (≤30V)
applications where space is not a concern and resettable
protection is preferred.

Description
Features
Applications
Cured, flame retardant
epoxy polymer insulating
material meets UL 94V-0
requirements
• Fast time–to-trip
• RoHS compliant, Lead-
Free and Halogen-Free*
USB hubs, ports
and peripherals
• Computers & peripherals
• Motor protection
• General electronics
• Automotive applications
I hold = Hold current: maximum current device will pass without tripping in 20°C still air.
I trip = Trip current: minimum current at which the device will trip in 20°C still air.
V max = Maximum voltage device can withstand without damage at rated current (Imax)
I max = Maximum fault current device can withstand without damage at rated voltage (Vmax)
Pd = Power dissipated from device when in the tripped state at 20°C still air.
R min = Minimum resistance of device in initial (un-soldered) state.
R 1max = Maximum resistance of device at 20°C measured one hour after tripping.
Caution: Operation beyond the specified rating may result in damage and possible arcing
and flame.
Agency Approvals
* Effective January 1, 2010, all 30R PTC products will be manufactured Halogen Free (HF). Existing Non-Halogen Free 30R PTC products may continue to be sold, until supplies are depleted.

Tape and Ammo Specifications
Devices taped using EIA468-B/IE286-2 standards. See table below and Figure 1 for details.
*Differs from EIA Specification
WARNING
• Users shall independently assess the suitability of these devices for each of their applications
• Operation of these devices beyond the stated maximum ratings could result in damage to the devices and lead to electrical arcing and/or fire
These devices are intended to protect against the effects of temporary over-current or over-temperature conditions and are not intended to perform as protective devices where such
conditions are expected to be repetitive or prolonged in duration
• Exposure to silicon-based oils, solvents, electrolytes, acids, and similar materials can adversely affect the performance of these PPTC devices
These devices undergo thermal expansion under fault conditions, and thus shall be provided with adequate space and be protected against mechanical stresses
• Circuits with inductance may generate a voltage (L di/dt) above the rated voltage of the PPTC device.
