HY-7110 Datasheet | Hytek

Features : ✦ ✦ ✦ ✦ ✦ Description : The HY7110 is a miniature proportionally controlled heater whose temperature can be programmed with a single external resistor. This device is ideally suited for regulating the temperature of sensitive electronic ponents such as microwave filters, optical waveguides, multiplexers and crystal oscillators. The HY7110 in a ceramic package can supply up to 28 Watts of power from an unregulated 28 Volt supply. Beryllia base for good thermal conduction Regulation temperature from 40°C to 100°C Electrically isolated from the case Epoxy sealed Hermetically sealed and military screened units available Maximum ratings: Rating Supply Voltage Reverse Voltage Power Dissipation Operating Temperature (Case) Storage Temperature Range Symbol VDD VR PD T MAX/MIN Value 35 - 50 35 100/- 20 - 65 to +150 Unit Vdc Vdc Watts °C °C Laser Diode Drivers Micro-heaters OUTLINE DIMENSIONS Operating characteristics: Characteristic Supply Voltage (Pin 1 to Pin 2) Steady State Supply Current @ VDD = +35 Vdc Temperature variation over operating voltage Temperature variation with load 0.018" diameter Cu with Au flash Symbol VDD IS ∆T V ∆T L TC RC TMAX PD Min +8 0.015 Max +35 1.0 2 10 Unit Vdc Adc °C °C °C Ω °C Watts Control Temperature Range Control Resistor Value Pin 3 to Pin 4 (See Figure 1) Maximum Control Temperature when Rc = 0Ω Turn on power at start-up @VDD = +28 Volts 50 0 100 35K 110 BERYLLIA BASE TWO TIMES ACTUAL SIZE HY-71 10 Micro-Heater TYPICAL BASE TEMPERATURE VS CONTROL RESISTOR SUPPLY CURRENT (AMPS) MAX START-UP CURRENT VS SUPPLY VOLTAGE MAX THERMAL POWER AVAILABLE VS SUPPLY VOLTAGE BASE TEMPERATURE °C CONTROL RESISTOR RC IN KΩ TYPICAL BASE TEMPERATURE LOSS WITH POWER DISSIPATION TEMPERATURE CHANGE °C SUPPLY VOLTAGE (VOLTS D.C.)
