NOTES

1. All values at reference temperature of 23°C (73°F) unless stated

otherwise.

2. Relay may pull in with less than “Must Operate” value.

3. “Maximum Coil Voltage” is the maximum voltage the coil can endure for

a short period of time.

4. Coil suppression circuits such as diodes, etc. in parallel to the coil will

lengthen the release time. We recommend to use coil suppression

circuits with a reverse breakdown voltage of around 3 times the nominal

coil voltage to achieve a fast release time.

5. For applications requiring long term high current carrying, we

recommend to reduce the coil energization to around half of the

nominal coil voltage as holding voltage.

6. For the gold plated signal contact a minimum load of 10mA/5V/50mW is

recommended.

7. Provide sufficient PCB cross section at Form A load terminals as a heat

spreader to dissipate power loss form contact resistance.

8. Relay adjustment may be affected if excessive shock is applied to the

relay or if undue pressure is exerted on the relay case. Dropped relays

must not be used anymore.

9. For automated dual wave soldering process we recommend preheating

with 120°C (248°F) for max. 120 seconds and a soldering temperature

of 260 ±5°C (500 ±9°F) for max. 10 seconds soldering time (max. 5

seconds per wave). For manual soldering we recommend 350°C

(662°F) max. temperature for max. 5 seconds. During the soldering

process, no force may be exerted on the relay terminals.

10. RTII (flux proof) relays must not be washed, immersion cleaned or

conformal coated.

11. During storage, transport and usage, ensure a dry, non-condensing and

non-icing environment.

12. Substances containing silicone or phosphorus must be avoided in the

vicinity to the relay as these will shorten its service life.

13. Avoid corrosive gases near the relay. Contact corrosion will lead to

malfunction.

14. Specifications subject to change without notice.

Compliance with IEC 62752, IEC 62955 or similar standards for short

circuit withstand is a function of both relay design and PCB layout.

ZETTLER's relay design and applications engineering teams have

developed an application note that contains important design suggestions

to optimize the performance of the relay with respect to its short circuit

current withstand capability.

In addition, as the overall performance depends on multiple factors such as

part arrangement and trace routing, compliance cannot be generically

guaranteed by ZETTLER. We strongly encourage customers to conduct

their own short circuit tests in accordance with IEC 62752, IEC 62955 or

similar standards in the context of their individual application design.
