DESCRIPTION
These PTC inrush current limiting or energy absorbing
thermistors consist of a medium resistivity doped barium
titanate ceramic with copper clad steel wires lead (Pb)-free
soldered to the Ag metalized pellet. A high temperature
silicone coating covers the ceramic body and is marked with
the cold resistance value, logo, EL and date code.

PACKAGING
PTC thermistors are available in 100 pieces (PTCEL13) or
50 pieces (PTCEL17) bulk packed or tape on reel option
500 pieces on request.

REQUIRED NUMBER OF PTC THERMISTORS TO LIMIT CURRENT AND ABSORB ENERGY
By using several PTC’s in a series / parallel network, the maximum current limitation and absorbed energy levels can be further
optimized. For homogeneous current and energy distribution it is recommended to combine only PTCEL of the same size and
matched resistance value. Energy absorption per PTC in a network depends on current distribution in the network and as such
on the individual PTC resistance value. PTCEL thermistors might be used in a series connection to further lower the inrush
current, but not to increase the maximum allowed voltage levels. Following formula may be used to calculate the minimum
number of PTCEL thermistors required in a DC link or other capacitor bank application to properly charge or discharge a given
amount of energy without follow current:

N  --------------------------------------------------------------2 x C th x  T sw - T amb 
Notes
• N is the number of PTCEL required in the network.
• C is the total capacitor value to charge or discharge in F.
• V is the maximum DC voltage on the capacitor C.
• Cth is the thermal capacity of one PTC in [J/K] (see table).
• Tsw is the minimum switching temperature of the PTCEL (130 °C).
• Tamb is the maximum ambient temperature at which the PTC needs to operate.
