~~ee~~| ## **Notes** - (1) The response time is the time the sensor responds to a 63.2 % step change in temperature, usually set to ΔT = 60 °C (25 to 85) unless mentioned differently. This step is generally conducted by quickly transferring the NTC from one liquid to another (generally water or oil) - (2) Measured with screw mounted on an aluminum heatsink of 100 cm[2] , thickness 1.5 mm, in still air at Tamb = +25 °C - (3) In still air on an aluminum plate - (4) The thermal gradient is the difference per °C between the true temperature of the surface to be sensed and the temperature measured by the sensor ## **AGENCY APPROVALS** - cUL certificate XGPU8.E148885 - ULus certificate XGPU2.E148885 ## **Note** - Agency approval documents, please see: www.vishay.com/ppg?29114&documents ## **PACKAGING** Available in plastic bags. - cULus recognized, file E148885 (UL category XGPU2/XGPU8) • Material categorization: for definitions of compliance please see www.vishay.com/doc?99912 ~~a~~ ## **APPLICATIONS** Thermistors used for surface temperature sensing and control in: - Computer equipment - MOSFETS, IC’s, power electronics, heatsink temperature control, LED emitter heat-sink control - Consumer appliances - Industrial equipment - Automotive equipment ## **DESCRIPTION** Miniature insulated chip thermistor with a negative temperature coefficient soldered to AWG#32 silver plated nickel and insulated cables, and mounted inside a mini lug tin plated copper barrel. ## **CAUTIONS AND WARNINGS ON MOUNTING AND HANDLING** Please read the special instructions: see www.vishay.com/doc?29221. - The sensor NTCALUG03A can be mounted by means of a screw M2 (stud #1, #2), or a screw M3 (stud #3, #4) for NTCALUG39A - For the type without connector, the electrical connection can be made by soldering, crimping, or welding - For the type with connector, see section Mounting Connector ## **DESIGN-IN SUPPORT** - Other resistance curves and tolerances are available on request - Consult Vishay for other lead length, other connector crimping, or other features - https://info.vishay.com/vishay-ntc-modification-request - 3D solid models: www.vishay.com/doc?29147 - NTC curve computation: www.vishay.com/thermistors/ntc-rt-calculator/ Revision: 23-May-2025 Document Number: 29114 **1** For technical questions, contact: nlr@vishay.com THIS DOCUMENT IS SUBJECT TO CHANGE WITHOUT NOTICE.
