HY-7110

Micro-heater

Miniature Proportionally

Controlled Heater

Description:

The HY7110 is a miniature proportionally controlled heater

whose temperature can be programmed with a single exter-

nal resistor. This device is ideally suited for regulating the

temperature of sensitive electronic components such as mi-

crowave 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.

Features:

✦ Beryllia base for good thermal conduction

✦ Regulation temperature from 40°C to 100°C

for clarity

Do not overtighten the mounting screws.

This may result in breaking the ceramic substrate.

NOTES:

1. Optimum heat transfer between the HY7110 and the device being heated occurs when a thermal compound, such as

Dow Corning 340, is applied to the mounting surface of the heater.

2. Operation is possible from 100 °C to 120°C, however electrical performance is not guaranteed.

3. Special environmental and electrical screening is available on request.

4. Special custom engineered micro-heater available on request.
