1. Circuit Design
1.1 Operating Temperature Range
1.2 Operating Power
The Multilayer Chip NTC Thermistors (hereafter referred to as ÒThermistorsÓ) are intended for general
consumer-type electronic (audiovisual, household, office, information & communication )equipment. It is
important to understand the features and specifications before making a selection.
Misuse may result performance deterioration resulting in short or open circuits.
For product designs which requires a high level of safety, make a careful analysis about how a failure
mode could affect the end products;
For the following applications, please consult us for a more detailed information or if you have any
questions about the intstructions below for safety or handling, or for any applications where
erroneous operation with this porduct may cause directly, or indirectly, hazardous situations which
could result in death or injury.

2 Submarine Equipment (submarine repeating equipment, etc.)
3 The Department of Defense
4 Transportation Equipment (motor vehicles, airplanes, trains, ships, traffic signal controls)
5 Power Generation Control Equipment (atomic power, hydroelectric power, thermal power plant control
6 Medical Equipment (life-support equipment, pacemakers, dialysis controllers)
7 Information Processing Equipment (a large scale computer system)
8 Electric Heating Appliances, Burning Apparatus
9 Rotary Motion Equipment
J Security Systems
The specified ÒOperating Temperature RangeÓ In
the Specification is absolute maximum and mini-
mum temperature rating. So in any case, each of
the Thermistors shall be operated within the
specified ÒOperating Temperature RangeÓ.
Thermistors, shall not be operated in excess
of the specified ÒMaximum Permissible
Electrical powerÓ.
Thermistors shall not be operated beyond
thespecified Maximum Permissible Electrical
Power, otherwise, burnout and damages could
occur. (if operated in ambienttemperatures
above 25 ¡C, power rating shall be derated in
accordance with the derating curve.)
In case of applications of the Thermistor to
temperature detection, the accuracy of the
detection may be greatly affected by the self-
heat generation and heat dissipation of the
Thermistor, even if the Thermistor is operated
under the specified Maximum Permissible Electrical
power before use.
The safety and reliability shall be checked in
your circuit.

2.1 Selection of Printed Circuit Boards
2.2 Design of Land Pattern
When the Thermistors are mounted and
soldered on an ÒAluminum SubstrateÓ, the
substrate has influences on the Thermistors
ability to withstand ÒTemperature CyclesÓ and
ÒHeat shockÓ because of difference in thermal
expansion coefficients between them. It should be
carefully confirmed that the actual board used
does not deteriorate the characteristics of the
Thermistors.
