Selection Notes

• The B constant and the 25 °C resistance together define the curve. Two parts with the same resistance but different B values are not interchangeable.
• Self-heating shifts the reading. Keep the measuring current low enough that dissipation stays in the milliwatt range.
• Tolerance is usually specified at 25 °C only. Off that point the error grows with the B tolerance.
