NTC Thermistors
NTCG Series(SMD, Pb Free) NTCG06/10/16/20 Types
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
• Small sized 0603 type (L0.6× W0.3× T0.3mm) series are avail-
•
able.
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.).
Product Conforming to RoHS Directive
Conformity to RoHS Directive: This means that, in conformity
with EU Directive 2002/95/EC, lead, cadmium, mercury,
hexavalent chromium, and specific bromine-based flame
retardants, PBB and PBDE, have not been used, except for
exempted applications.
Good solderability.
Layered internal electrode structure.
Product series provides a wide range of resistances and B
constants.
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.

B constant is calculated from the resistance at 25˚C and 85˚C
The B constant indicates the magnitude of a change in a zero-load resistance value to a temperature, and is obtained based on arbitrary
two temperatures in resistance-to-temperature characteristics.
B constant calculation formula
B: B Constant (K)
T1: Arbitrary temperature (K)
T2: Arbitrary temperature different from T1 (K)
R1: Zero-load resistance value at temperature T1(
Ω
)
R2: Zero-load resistance value at temperature T2(
Ω
)
Each temperature is measured in absolute temperature. 0°C=273.15K
