Description

The ESRD8R2M16R is a polymer capacitor used in electronic components. It is designed to stabilize the temperature of a laser diode or passive component in telecommunications equipment. The device utilizes a negative temperature coefficient (NTC) thermistor to sense the temperature and is controlled by a monolithic controller called ADN8830. The target temperature is set through an analog input voltage, allowing for precise temperature control. The controller features a PID compensation amplifier with high stability and low noise, ensuring accurate temperature stabilization. The ESRD8R2M16R also provides voltage outputs to monitor the temperature and voltage across the thermoelectric cooler (TEC).
