Positive Thermal Coefficent -
RLVR240 Series
Positive Thermal Coefficient devices(PTC),provide over-current protection
for electrical and electronic devices.They function using conducting strips
of metal imbedded inside polymers.Under normal conditions,the devices
resistance is near zero,but over-current conditions will heat the PTC and
expand the polymer,increasing the impedance.When current returns to
normal,the components cool down,returning to their original shape and very
low levels of resistance.
Features
• I(hold): 0.12~2.0A
• 240VAC Operating voltages
• Radial leaded devices
• Over-current protection
• Very high voltage surge capabilities.
• Available in lead-free version.
• Fast time–to–trip
• RoHS compliant, Lead- Free and Halogen-Free
Applications

Manual Soldering Recommendation Parameters
Items
Soldering condition
Soldering time
Soldering position
Conditions
The highest power of the manual soldering iron should be 30W or less, soldering temperature
should not be higher than 280℃ .
The soldering time should be kept within 3 seconds, otherwise it might cause insulation layer
cracking, and increased part resistance.
The distance on the leads between the soldering point and bottom of the PPTC body should be
equal or greater than 4mm.
The soldering iron should not contact the PPTC body except the leads. If the soldering
conditions are kept to lower temperature, less time and larger distance, the outcome of the
soldering will be better.
Other
Notes: 1. Before using the device must be stored in the original bags, if the storage conditions do not guarantee, the device may not be able
to meet the given value.
2. The devices can’t used for reflow soldering.
