NOTES:
1. Dimensions are shown in inches/millimeters
Unless otherwise specified, tolerance = Inches: ±0.010
= Millimeters: ±0,25
2. For non-RoHS parts replace SM prefix with 42- (e.g. SM538-1 becomes 42-538-1)
3. Terminal finish is compliant to RoHS requirements. Solder in accordance with
J-STD-020C.
