FLAT POLARIZED RELAY
GQ-RELAYS
FEATURES
• Compact flat body saves space
With a small footprint of 10.6 mm (L) × 7.2
mm (W) .417 inch (L) × .283 inch (W) for
space savings, it also has a very short
height of 5.2 mm .205 inch. (Standard PC
board type.)
Due to highly efficient magnetic circuit de-
sign, leakage flux is reduced and changes
in electrical characteristics from compo-
nents being mounted close-together are
minimized. This all means a packaging
density higher than ever before.

• Outstanding surge resistance.
Surge withstand between open contacts:
1,500 V 10×160 µs (FCC part 68)
Surge withstand between contacts and
coil: 2,500 V 2×10 µs (Bellcore)
• Nominal operating power: 140 mW
• Outstanding vibration and shock re-
sistance.

•The use of twin crossbar contacts en-
sures high contact reliability.
Destructive shock resistance:
1,000 m/s2 {100G}
AgPd contact is used because of its good
sulfide resistance. Adopting low-gas
molding material. Coil assembly molding
technology which avoids generating vola-
tile gas from coil.
Functional vibration resistance:
10 to 55 Hz (at double amplitude of 3.3
mm .130 inch)
Destructive vibration resistance:

*6 Half-wave pulse of sine wave: 6 ms.
❇1 This value can change due to the switching frequency, environmental conditions,
and desired reliability level, therefore it is recommended to check this with the
actual load.
*7 Detection time: 10µs.
*8 Refer to 5. Conditions for operation, transport and storage mentioned in
AMBIENT ENVIRONMENT (Page 61)
❇2 The upper limit for the ambient temperature is the maximum temperature that
can satisfy the coil temperature rise. Under the packing condition, allowable
temperature range is from –40 to +70°C –40° to +158°F.
