Philips Components
Thermistors for overload protection
PTC 56 V and 265 V (Ts = 120 °C)
Product specification
2322 66. 0/1/3.... series
FEATURES
• Different voltages to be chosen in
function of the application
• Available in three mechanical
versions
– 2322 66. 0.... naked discs
– 2322 66. 1.... leaded
– 2322 66. 3.... taped, on reel
(to diameter 12.5 mm)
• Wide range of trip and non-trip
currents: from 17 mA up to 3 A for
the trip current
• Wide range of resistance: from
1.6 Ω up to 1.9 kΩ
• Small ratio between trip and
non-trip currents
(It/Int ≤ 1.5 at 25 °C)
-I-In--t-t---(-(--a--a--t--t--1-5--0--5----°-°--C-C---)--)-
= 2
• Leaded parts withstand mechanical
stresses and vibration.
