DESCRIPTION

CONTACT  
The TO-5 relay, originally conceived and developed by Teledyne, has become one of the  
industry standards for low-level switching from dry circuit to 1 ampere. Designed for high-  
density PC board mounting, these TO-5 relays are some of the most versatile  
ultraminiature relays available because of their small size and low coil power dissipation.

CONTACT  
The H Series high-temperature TO-5 relays are designed for reliable operation in  
elevated ambient temperatures up to 200°C. Special material selection and processing  
provide assurance of freedom from contact contamination and mechanical  
malfunctioning that might otherwise be caused by ultra high ambient temperature  
conditions.

Typical applications:  
• Oil exploration (down hole) instrumentation  
• High temperature industrial and process control instrumentation

ENVIRONMENTAL AND  
PHYSICAL SPECIFICATIONS  
By virtue of its inherently low intercontact capacitance and contact circuit losses, the H  
Series relays have proven to be excellent ultraminiature RF switches for applications with  
frequency ranges well into the UHF spectrum (see Figures 1 and 2).

of a magnetic field, it is necessary to apply the correct polarity to the relay coils as  
indicated on the relay schematic.

When latching relays are installed in equipment, the latch and reset coils should not be  
pulsed simultaneously. Coils should not be pulsed with less than rated coil voltage and  
the pulse width should be a minimum of three times the specified operate time of the  
relay. If these conditions are not followed, it is possible for the relay to be in the  
magnetically neutral position.
