Shock
The K Series high-shock TO-5 relays are designed to withstand shock levels up to 4000
g’s, .5 millisecond duration. Special material selection and construction details provide
assurance that critical elements of the relay structure and mechanism will not be
permanently displaced or damaged as a result of extremely high g level shocks.
By virtue of their inherently low intercontact capacitance and contact circuit losses, the
K Series relays have proven to be excellent subminiature RF switches for applications
with frequency ranges well into the UHF spectrum. A typical RF application for the TO-5
relay is in handheld radio transceivers, wherein the combined features of good RF
performance, small size, low coil power dissipation and high reliability make it a
preferred method of T-R switching (see Figure 1 and 2).
Temperature (Ambient)
Shock
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 highdensity PC board mounting, its small size and low coil power dissipation make the TO-5
relay one of the most versatile subminiature relays available.

upon removal of power from Coil B, but will snap
back to position B upon energizing Coil A. Since operation depends upon cancellation
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.

1. Relay contacts will exhibit no chatter in excess of 10 µsec or
transfer in excess of 1 µsec.
2. “Typical” characteristics are based on available data and are
best estimates. No on-going verification tests are performed.
3. Unless otherwise specified, parameters are initial values.
4. Survival only — contact chatter may occur.
