**Leaded Thermistors** Glass Encapsulated Thermistor ## ~~-~~ USUG1000 Series UL Recognize ~~d DO 35 Glass Encapsulated Thermistors~~ ## **Description** Littelfuse low cost interchangeable glass encapsulated thermistors are manufactured using super stable, precision NTC chips which are hermetically sealed in a glass (DO-35 diode style) package. The result is a device which exhibits excellent long term reliability and stability even when subjected to severe environmental or thermal conditions. They are well suited for uses where their interchangeability eliminates the necessity for costly individual circuit calibration. Their uniform dimensions and axial lead configuration make them especially suitable for use with automatic insertion equipment. ## **Features** **==> picture [245 x 99] intentionally omitted <==** **----- Start of picture text -----**<br> Agency Approvals<br>Lo<br>AGENCY AGENCY FILE NUMBER<br>E232830<br>eS<br>Dimensions<br>**----- End of picture text -----**<br> **==> picture [238 x 81] intentionally omitted <==** **----- Start of picture text -----**<br> GLASS<br>BODY<br>A<br>B<br>= yo ) ht<br>C<br>**----- End of picture text -----**<br> - [Temperature rating = ] •[Excellent long-term ] -40 to +150°C stability - [Hermetically sealed ] •[Tinned CSS Lead ] glass package Wires are Solderable or Weldable ## **Part Numbering System** **==> picture [236 x 97] intentionally omitted <==** **----- Start of picture text -----**<br> USUG1000-10 3 G<br>DO-35 UL Series | L Resistance Tolerance<br>G = ±2%<br>J = ±5%<br>Resistance @ 25ºC<br>K = ±10%<br>Base Value<br>Multiplier, power of 10<br>Ex. 103 = 10 Ω x 10 [3 ] = 10,000 Ω<br>**----- End of picture text -----**<br> Note: Not all combinations of Part Number codes are available.
