2381 66. 5...4/PTCCL..H...CBE
Vishay BCcomponents
12 to 24 V PTC Thermistors
For Overload Protection
FEATURES
• Wide range of trip and non-trip currents: from 350 mA up
to 3 A for the trip current
• Wide range of resistance: from 0.16 Ω up to 3.5 Ω
• Small ratio between trip and non-trip currents
(It/Int = 1.5 at 25 °C)
• High maximum inrush current (up to 33 A)
• Leaded parts withstand mechanical stresses and vibration
• Component in accordance to RoHS 2002/95/EC and
WEEE 2002/96/EC
APPLICATIONS
• Telecommunications
• Automotive systems
• Industrial electronics
• Consumer electronics
• Electronic data processing
DESCRIPTION
These directly heated thermistors have
a
positive
temperature coefficient and are primarily intended for
overload protection. They consist of a naked disc with two
tinned brass or copper clad steel leads and coated. Leadless
disks and leaded disks without coating are available on
request.
MOUNTING
The PTC Thermistors are suitable for processing on
automatic insertion equipment.

Notes
1. The thermistors are clamped at the seating plane.
2. max is the maximum overload current that may flow through the PTC when it passes from the low ohmic to the high ohmic state.
