NTC Thermistor Resistors 10 Values 81 PCS Inrush Current Limiter Temperature Sensors Assorted Kit Assortment(3D-25,5D-7,5D-9,5D-11,5D-15,8D-9,10D-9,10D-11,20D-9,47D-15)

This was an assortment of NTC's that can be used for switching power supply repair or maybe to limit the inrush current for a antique radio restoration.

If you are ordering these, you probably already know what they are and how they're used. I am writing this review to correct some incorrect information given in another review about the part numbers.The manufacturer data sheet (see pictures) reveals that the part numbers are in the following format:Resistance (cold) and diameter only -- nothing about current rating. You need to look that up on the data sheet! For example, a 5D-7 has 5 ohms at room temp, and a diameter of 7mm. If you look this up on the data sheet (see picture) you'll see that it is rated at only 2 amps of steady state current (not 7 amps).Yes, the larger the diameter, the more current they can handle, but the diameter "number" is NOT the current rating. Now you know, and can purchase (and use) accordingly.

the part number description is as follows ex: 5=resistance D=diameter 20=amperes

good value
