Update:18-11-2020

According to the size of the relay:

1) Miniature relays: relays with the longest side dimension not greater than 10 mm.

2) Ultra-compact miniature relays: relays with the longest side dimension greater than 10 mm, but not greater than 25 mm.

3) Miniature relays: relays with the longest side dimension greater than 25 mm, but not greater than 50 mm.

Note: For sealed or enclosed relays, the external dimensions are the maximum dimensions of the relay body in three mutually perpendicular directions, excluding the dimensions of mounting parts, lead-out ends, beading, crimping, flanging and sealing solder joints.
