1) Long-term heat and moisture will directly lead to the decline in the level of insulation resistance, resulting in complete failure. In particular, long-term storage or use of exposed insulation during the dust and other contaminated by d[…]

1, in order to prevent the pollution of the terminal surface, should not be in direct contact with the terminal, otherwise, may result in decreased solderability. 2, the location of the lead should be In agreement with the holes on the prin[…]

The contact is the most important part of the relay. The working reliability of the contact is affected by the material of the contact, contact voltage and current (especially on and off voltage and current waveform), load type, on-off rati[…]

Welding process First, coated flux PCB board non-plastic sealed relays vulnerable to flux contamination, it is recommended to use solder-type or plastic-enclosed relays to prevent the flux gas from the lead-out end and the base and the shel[…]

1, the installation direction If the direction of installation and the impact resistance of the relay in the same direction, give full play to the performance of the relay. It is suggested that the direction of impact be perpendicular to th[…]

Relay is a kind of automatic control device whose output will change abruptly when input quantity (electricity, magnetism, sound, light and heat) reaches a certain value. And the car relay is the relay used in the car, this kind of relay sw[…]
