Leaded NTC Thermistors 

Radial Thermistors

Radial Leaded Thermistors are available in 3 principle forms, of which all are encapsulated in an epoxy coating.

DC30 RM16 CN25
body Ø= 4.5 ~ 7.0mm body (max) = 1.8 x 7.0mm body (max) = 3.5 x 4.0mm
lead Ø= 0.4mm lead Ø= 0.16mm lead Ø= 0.3mm
105mW 51mW 59.5mW
1.4mW/°C 0.6mW/°C 0.7mW/°C
-40 ~ +100°C -40 ~ +110°C -40 ~ +110°C
  "thin lead"  

Values shown below are available in 5% & 3% tolerances for the RM16 and CN25. The DC30 is available in 10% & 5% tolerances. The Beta (calculated between 25°C and 50°C) ranges from 2750 (low resistance values) to 4500 (high resistance values). In all cases the Beta tolerance is ±3%. There are several values in the RM16 and CN25 which have multiple Betas (B-values) available. They are indicated in the chart below. (italic & bold)

There is a reduced list of "tight tolerance" parts in the RM16 and CN25 series. These parts are specified at 1%, 2% and 3% resistive tolerance and Beta tolerance is ±1%. Contact us for available values.

A non-standard value (or Beta) may be available. Please contact us if you are unsure of availability.
