RESISTANCE VALUE RANGE

TYPICAL USED SET AND TDK PRODUCT NAMES

LIST OF SERIES BY TYPE

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(

R2: Zero-load resistance value at temperature T2(

Each temperature is measured in absolute temperature. 0°C=273.15K
