## Description

The 135-504QAG-J01 is a glass-encapsulated NTC thermistor from Honeywell's Fenwal Electronics line, featuring a nominal resistance of 100 kΩ at 25°C with a 10% tolerance and Curve 16 R-T characteristic. Constructed with hermetically sealed glass encapsulation over a rugged DO-35 style package, this negative temperature coefficient thermistor delivers high-temperature capability spanning -60°C to +300°C, with a dissipation constant of 2.5 mW/°C in still air and thermal time constant of 4 seconds maximum. The component utilizes tinned copper-clad steel leads compatible with both soldering and welding operations, with lead forming and cutting options available for radial mounting configurations.

This thermistor is engineered for temperature sensing and compensation applications requiring reliability in demanding thermal environments, including industrial process control, HVAC systems, automotive thermal management, and power supply over-temperature protection circuits. The hermetic glass seal provides exceptional moisture resistance and long-term stability compared to epoxy-coated alternatives, while the uniform axial-lead dimensions support high-volume automated assembly in both bulk and tape-and-reel packaging formats. The 135-504QAG-J01 is available from stock for immediate delivery, with alternate tolerance grades of 1%, 2%, 3%, and 5% offered across the product family for precision interchangeability requirements from 0°C to 100°C.

GLASS ENCAPSULATED CHIP Thermistors are a high quality line of Low Cost, Hermetically Sealed, glass encapsulated units that evolved from Fenwal Electronics, Inc.'s highly successful and field-proven Standard Chip Series. Added to the feature of "True Low Cost" is "Delivery from Stock" in high volume. They are designed to cover the full temperature range of -60° C to +300° C. The uniform dimensions are ideally suited for automated assembly. A rugged sensor, it is designed for any application which demands reliability at a Low Cost. The tinned copper clad steel leads are both solderable and weldable, and leads may be formed/cut for radial lead applications. 

Fenwal Electronics’ Glass Encapsulated Chip Thermistors are available to our customers Bulk Packaged or on Tape and Reel.
