Product Description

35mm Radial Disc Thermistor NTC 15A 32A 28A 25A 23A 22A 21A 20A 19A 18A 17A 16A 14A 13A 11A 10A For Surge Current Protection

Inrush Current Limiters are used to reduce the inrush current that occurs when an electrical device is switched on.

High inrush current is the result of the maximum instantaneous input current drawn by an electrical device during the initial power up.

As technology continues to advance, most systems today run efficiently and maintain a low impedance which in turn contributes to high inrush current.

Technical requirements:

1) Zero Power Resistance: R25:10Ω±20%

2) B-value:B25/50: 3200K±10%

3) Tinned copper wire

4) Black silicon resin

5) Meet environmental protection requirements:RoHS

Can be installed into the power circuits of:
Power supplies and inverters
Uninterruptible Power Supplies
Energy saving lamps
Electronic Ballasts
Filament Protection of various types of lamps
Some types of heaters

Shock resistance,humidity resistance, heat resistance, good heat dissipation
Fully insulated, suitable for printed circuit boards.
The wire is wound on he porcelain rod and then the joint is welded to produce accurate resistance value and prolong the service life.
Resistance is made of metal oxide film (MO) instead of winding.
Excellent heat resistance, low resistance temperature coefficient, linear change.
It can withstand short-term overload, low noise, and the resistance value has not changed over the

years.
Good explosion-proof performance for protection
