Technical Data Sheet for NL3021T-AC/-BC Thermoelectric Module NOMINAL PERFORMANCE IN NITROGEN Hot Side Temperature (°C) Δ Tmax (°C): Qmax (watts): Imax (amps): Vmax (vdc): AC Resistance (ohms): PRODUCT FEATURES • • • • 27 96 0.33 1.3 1.9 1.42 50 109 0.38 1.3 2.2 -- ORDERING OPTIONS RoHS EU Compliant Pretinned metallized ceramic surface(s) with 117°C solder. Thermistor mounted on edge of cold side ceramic. (Calibration available.) Elevated temperature burn-in with test data provided. Model Number NL3021T-01 NL3021T-02 NL3021T-03 NL3021T-04 Description Both Surfaces are Metallized Hot Side Exterior is Metallized No Exterior Metallization Both Surfaces are Metallized with Pretinned Hot Side OPERATION CAUTIONS INSTALLATION For maximum reliability, storage and operation below 85°C in a non-condensing environment is recommended. To minimize thermal stress, use linear/proportional temperature control or a similar method rather than an ON/OFF method. Recommended mounting methods: Bonding with thermal epoxy or soldering with metallized ceramics. For additional information, please refer to our TEM Installation Guide.
