NTC Thermistors
NTC(Negative Temperature Coefficient) Thermistors are manufac-
tured from sintered metal oxides. Each thermistor consists of a
combination of two to four of the following materials: Manganese,
Nickel, Cobalt and Copper. NTC thermistors are semiconductor
resistors that exhibit decreasing resistance characteristics with
increasing temperature. TDK thermistors have low thermal time
constants which result in extremely high rates of resistance
change to accurately track the temperature.

FEATURES
USED SET
• Small sized 0603 type (L0.6×W0.3×T0.3mm) series are avail-
able.
• Equipment related to mobile communication
TCXOs (temperature compensated type quartz oscillator), RF
circuits (power amp circuits, temperature monitoring circuits),
LCD panel temperature compensation circuits, battery pack
temperature compensation circuits
• Lead (Pb) free product.
By using lead-less terminal electrodes and electroplating (Ni-
Sn), this product realized excellent solderablity and soldering
heat resistance, comparing with the conventional eutectic
mixture solder and lead-free solder (Sn/Ag/Cu, etc.).
• Good solderability.
• Computer related equipment
CPU periphery temperature monitoring circuits, temperature
compensation circuit of optical pickup for DVD writing, tempera-
ture compensated circuit in HDD
• Layered internal electrode structure.
• Product series provides a wide range of resistances and B
constants.
• DVC/DSC devices
Auto-focus circuits, plunger peripheral circuits, battery pack tem-
perature control circuits
• Good stability of resistance value after soldering.
• The 0603, 1608 and 1005 types provide 3 different shapes with
identical resistance-temperature characteristics.
• Attains less that low floating capacitance (using TCXO) in the
high frequency region.
• Equipment related to car audio
Various types of pickup temperature compensation circuits, tem-
perature compensation for various types of circuits
