Note: The data shown above are initial values. 

*1. The contact resistance was measured with 10 mA at 1 VDC with a voltage drop method. 

*2. The insulation resistance was measured with a 500 VDC megohmmeter applied to the same parts as those used for checking the dielectric strength (except between the set and reset coil). 

*3. This value was measured at a switching frequency of 60 operations/min and the criterion of contact resistance is 50 Ω . This value may vary, depending on switching frequency, operating conditions, expected reliability level of the relay, etc. It is always recommended to double-check relay suitability under actual load conditions.

## ■ **Precautions** 

- **Please refer to “PCB Relays Common Precautions” for correct use.** 

## **Correct Use** 

## ● **Long-term Continuously ON Contacts** 

Using the Relay in a circuit where the Relay will be ON continuously for long periods (without switching) can lead to unstable contacts because the heat generated by the coil itself will affect the insulation, causing a film to develop on the contact surfaces. We recommend using a latching relay (magnetic-holding relay) in this kind of circuit. If a single-side stable model must be used in this kind of circuit, we recommend using a fail-safe circuit design that provides protection against contact failure or coil burnout. 

## ● **Relay Handling** 

When washing the product after soldering the Relay to a PCB, use a water-based solvent or alcohol-based solvent, and keep the solvent temperature to less than 40°C. Do not put the Relay in a cold cleaning bath immediately after soldering. 

## ● **Double-switching load in two poles** 

Double-switching in two poles as shown in the figure below, one pole and two pole interval may become MBB (Make Before Break) mechanically according to the timing of the point of **G 6** contact switching (By the short-circuit mode), and the **A** malfunction might be caused. 

In such a circuit, direct electric switching should be avoided, and concern for contact to be carried after the contact of Relay absolutely switches in condition of no load.
